BPPT to install tsunami early warning buoy in Aceh

Antara News, Sunday, April 18, 2010 18:54 WIB

Banda Aceh, Aceh (ANTARA News) - The Agency for the Assessment and Application of Technology (BPPT) is to install a tsunami early warning buoy in the Simeulue waters, Aceh province, early next week.

"We plan to arrive in the waters off Simeulue`s northern coast early next week to install the tsunami early warning buoy," the chief of a team aboard research vessel Baruna Jaya III, Iyan Turyana, said on Saturday.

He made the remark when receiving Aceh Deputy Governor Muhammad Nazar aboard the research vessel which had just arrived in Aceh after installing a tsunami early warning buoy in the waters of Mentawi islands, West Sumatra province.

The research vessel with 22 researchers and 17 crew members aboard is expected to leave Malahayati pier in Aceh Besar district for the Simeulue waters on Sunday.

The tsunami early warning buoy called Ina buoy is assembled by BPPT. The equipment is capable of detecting signs of whether or not there is quake vibration in the sea.

The Ina buoy which was for the first time developed in Indonesia in 2006 consists of buoy unit and bottom unit.

The buoy unit to be installed in the Simeulue waters will float on the sea surface and the bottom unit will be placed 15 meters below the sea surface. The equipment will any time send signs of natural movement beneath the sea and later send the information to the monitoring station at the BPPT by satellite.

Most of Aceh`s coastal areas was devastated by a tsunami triggered by a magnitude 8.9 earthquake on December 26, 2004, killing around 200,000 people.

The province was again rocked by a powerful quake on April 7, 2010.

Earthquake preparations 'a disgrace', says seismologist

More quakes will happen and more planning is needed, scientists say

The lack of earthquake planning by the international community is a "disgrace", a leading seismologist has said.

Professor John McCloskey said that governments must prepare for quakes, rather than act after the event.

The University of Ulster expert led the analysis of the quake that started the Indian Ocean 2004 tsunami.

"It is an international disgrace that we appear not to have made the smallest progress in preparation," he said.

"The 'international community' is very good at preparing for war but has failed completely to prepare to help the poor, who are always the ones to suffer in these events.

"If we want to claim to be civilised we need to ensure that we never see these scenes again."

In a letter to the journal Nature Geoscience he and his team warn that a huge wave-generating quake capable of killing as many people as in the 2004 Indian Ocean tsunami could strike off the Indonesian island of Sumatra, with the city of Padang in the path of destruction.

The danger comes from a relentless increase in pressure over the last 200 years on a section of the Sunda Trench, one of the world's most notorious earthquake zones, which runs parallel to the western Sumatra coast.

This section, named after the Mentawai islands, "is near failure," the letter warned.

Professor McCloskey said that governments were "refusing the accept the inevitable".

"Earthquakes happen, they kill people, they will kill more and more people if we don't organise ourselves properly," he said.

He said the earthquake which rocked Padang, western Sumatra in September last year killing more than 1,000 people was not the "great earthquake" scientists were waiting for but it may have made the next massive earthquake more likely.

Professor McCloskey is the head of the Geophysics Research Group at the UoU's Environmental Sciences Research Institute.

He said that while earthquake prediction was "as far off as ever" all the indicators are pointed to western Sumatra as a massive quake location.

"Scientists cannot forecast the exact size of the earthquake but in this case there is complete agreement that it will be very strong, probably bigger than magnitude 8.5, dwarfing the energy release in the Haitian quake," he said.

"We also cannot say for sure what size the tsunami will be but it has the potential to be very destructive - maybe even worse than 2004.

"But the future need not look like Haiti. We know this earthquake is coming and we might have years or even decades to prepare.

"Given the unfolding scenes of carnage following the Haiti earthquake and the completely inadequate speed of the international response, the responsibility on the Indonesian government, the international community and the international NGOs is enormous.

"We must work urgently to prepare for this earthquake if we are not to witness again the awful scenes of children dying for want of a few stitches or a cast for a broken leg."

The science of catastrophe: tsunamis and how they work

Five years ago, 200,000 lives were wiped out. Experts expect another a huge quake under Indonesia.

Reuters, December 26, 2009


The devastating 2004 Indian Ocean tsunami, caused by a major earthquake under the seafloor north of Aceh in Sumatra, struck five years ago today, killing more than 200,000 people. Scientists say another massive undersea earthquake is long overdue beneath the Mentawai islands in Indonesia and could trigger another deadly tsunami any time.


Here is some of the science behind the process.


How tsunamis occur


In the Sumatra area, tectonic plates meet in a subduction zone -- a place where the boundaries of one plate are forced beneath the other plate. The Indo-Australian plate is sliding northeastward (about 2.8 inches a year) and dipping under the Eurasian plate, along a fault line called the Sunda megathrust which runs southwest from Myanmar down Indonesia toward Timor.


Tremendous geological strain builds over many decades until a section of the megathrust gives way. This rupture causes the oceanic plates beneath Sumatra to lurch forward suddenly, by many yards, in a big earthquake.


If the ocean floor ruptures, it suddenly moves a massive amount of water. This is what happened in the earthquake that caused the deadly Indian Ocean tsunamis of December 2004.


Major quakes that rupture the ocean floor are usually shallow quakes occurring at a depth of less than 44 miles. The quake that caused the 2004 tsunami was about 20 miles below the seafloor.


Tsunamis rise up


On the ocean surface, tsunamis start as a ripple capable of passing under a ship unnoticed, but they become giants as they approach land and the ocean becomes shallow.


A tsunami is not a single wave, but a series of waves. The waves can travel across the ocean at speeds of up to 620 miles an hour, the speed of a jet aircraft.


The vast size of the Pacific Ocean and the large earthquakes associated with the Ring of Fire combine to produce deadly tsunamis in the Asia-Pacific. A tsunami can travel across the Pacific Ocean in less than a day.


As the waves approach land, the ocean recedes dramatically, exposing reefs as the waves draw the water out.


As the trough of the wave drags along the sea floor, slowing it down, the crest rises up dramatically and sends a giant wall of whitewater onto land. The first wave may not be the biggest.


The destructive force of a tsunami comes not from the height of the wave, but from the volume of water moving.


It is as if the ocean floods the coast, smashing everything in its path, and then just as quickly recedes.


Many people who survive the initial wave impact are washed out to sea as the tsunami recedes.


World's worst


  • The 2004 Indian Ocean tsunami was the world's most deadly, killing about 226,000 people, with a wave height about 100 feet.

  • The world's biggest tsunami, caused by a magnitude 8 quake that caused a massive landslide, hit the remote Lituya Bay in Alaska on July 9, 1958. As the wave swept through Lituya Bay, it was forced to rise up, reaching an estimated height of 1,720 feet on the other side of the bay, becoming a mega-tsunami. The sparsely populated bay was devastated, but damage was localized.

  • The Krakatau island volcanic eruption of 1883 generated giant waves reaching heights of 125 feet, killing some 30,000 people. It was the most violent volcanic eruption in modern history.

Indonesia's next big quake due under Mentawais

In Sumatra, Waiting for Big One to Hit in Next ‘30 Seconds to 30 Years’


Reuters, by Michael Perry, Mon Dec 21, 2009 5:47am IST

SYDNEY (Reuters) - A massive undersea earthquake is long overdue beneath the Mentawai islands in Indonesia and could trigger another deadly tsunami, say scientists mapping one of the world's most quake-prone zones.


Unlike the 2004 Indian Ocean tsunami, which killed around 226,000 people, this tsunami is expected to be smaller but may be very deadly as it would hit Sumatra's densely populated coast.


"The size of the tsunami may not be as big, but the problem is the size of the population is about three times as great as Aceh," Kerry Sieh, director of the Singapore-based Earth Observatory, told Reuters.


A major quake measuring around 8.6 magnitude is expected beneath Siberut Island, along the Sunda megathrust, where the Indo-Australian tectonic plate butts up against the Eurasian plate -- one of the world's most active fault lines.


Exactly when the big quake will strike is not known.


"We say most likely in the next few decades. Thirty seconds to 30 years, somewhere in there," said Sieh, who has studied geological records showing that for the past 700 years, major quakes have occurred along the Sunda megathrust every 200 years.


There have been three major quake cycles: the late 1300s, the 1600s, and between 1797 and 1833.


"The timing between those three sequences is about two centuries," said Sieh, adding a section of the megathrust under Siberut has not ruptured for 200 years, so it is due to slip and cause a major quake.


SUPERQUAKE CYCLES


The Sunda megathrust extends from Myanmar in the north and sweeps in a southeast arc through Sumatra, Java and toward Timor.


The northern 1,600 km (1,000 mile) section of the fault, from Myanmar to Aceh, ruptured in 2004 sending the deadly Boxing Bay tsunami out into the Indian Ocean.


"The Boxing Bay quake reset the (super earthquake) cycle for that segment of the fault," Mike Sandiford at the School of Earth Sciences, University of Melbourne, Australia, told Reuters.


"The fault slipped up to 20 meters (60 feet) and that is like several hundred years of plate convergence. It should take several hundred years, if not longer, to accumulate the stress in the system to rupture on that particular strand."


The Sunda megathrust is made up of three distinct sections.


In March 2005, a powerful quake hit the second section near Nias island, causing more than 11-meter (33-feet) deformations beneath the island.


In 2007, an 8.4 and a 7.8 earthquake hit the southern end of the third section, the "Mentawais Patch," but not the northern part of the "Mentawais Patch."


"Now we have another 300 km that has not yet failed. It hasn't failed since 1797," Sieh said.


The 2009 Padang earthquake on September 30, while large has not relieved any pressure beneath the Mentawais, as it resulted not from a rupture of the megathrust, but was on a deeper fault.


"It may have potentially loaded that segment that has not ruptured for long time. It may have taken us closer to the big failure," said Sandiford.


"Because that (pressure) has not been released in the Padang region, we know the stress has been building and it must eventually be released. The sort of stress which ultimately led to the big rupture at the northern end of Sumatra on Boxing Day."


QUAKE SCENARIOS


One reason the Sunda megathrust generates major quakes is because it has very long fault planes that can slip as one. But because it bends as it runs south through Indonesia, scientists believe big quakes are limited to each section of the megathrust.


Sandiford says a 30-km (18-mile) fault could generate a maximum 7 magnitude quake, a 300-km (190-mile) fault a maximum 8 magnitude, and a 1,000-km (62-mile) fault a maximum 9. The 2004 quake was over a fault some 1,600 km (1,000 mile) long.


"The Boxing Day earthquake was huge. We have only had three or four of those quakes in the last 100 years or so," he said.


Singapore's Sieh paints two scenarios for the next big quake. The first is an 8.6 quake on the northern section of the "Mentawais Patch."


"There is only one piece of data that tells us it last broke in 1797. If we are wrong, it may be that the last event was the 1680s. If that is the case, we could have a significantly greater uplift and significantly larger tsunami," he said.


Recent studies by Sieh suggest a second scenario, where another big quake could occur along the same section of the megathrust that caused the 2004 Boxing Day tsunami.


While the middle of this section ruptured up to 25 meters (76 feet) in 2004, the lower part only slipped 10 meters (30 feet), leaving hundreds of years of stress still to be released.


"We are wondering whether there could be another big earthquake down in the south end of the 2004 section, which could break sometime in the next few decades as well," Sieh said.


The Mentawais fault line runs under the sea and any major quake is expected to rupture the ocean floor causing a tsunami.


In 2004 the quake spread a tsunami across the Indian Ocean to India and Africa. A tsunami generated from a Mentawais quake would send a wave southwest out into the empty Indian Ocean.


But the wave would also hit Sumatra's densely populated coast between Padang and Bengkulu, although the Mentawais island chain would help dissipate the wave's energy before it hit shore.


Scientists say there is little data linking a major quake with Indonesia's super volcanoes, like Sumatra's Lake Toba, saying a volcano must be ready to erupt in the first place.


Toba erupted around 74,000 years ago in what is believed to be the largest volcanic eruption in the last 2 million years.


Some scientists suggest the mega eruption may have accelerated a glacial shift in climate, by spewing 2,800 cubic kms of debris into the atmosphere, dramatically dropping the earth's surface temperature and sparking an ice age.

Hundreds of Buddhist residents on Sunday joined a prayer in front of a mass cemetery for people who died in the deadly 2004 Indian Ocean tsunami that hit Aceh five years ago.


The followers also took part in other rituals such as releasing flowers and lanterns to the Ulee Lheu Sea.


One of the event’s organizers, Yuswar, told news portal tempointeraktif.com this commemoration was aimed at praying for the Buddhists killed during the disaster.


“The rituals will continue until Dec. 26,” Yuswar added.


Apart from Buddhists, Islamic followers will hold similar prayers on Dec. 26.

Banda Aceh's triumph over war and disaster

The Indonesian island was wrecked by conflict before natural devastation, in the form of the 2004 tsunami, proved a catalyst for change

The Independent, Sunday, 20 December 2009, By Kathy Marks

In a fishing village west of Banda Aceh, young men gather in an outdoor coffee shop at dusk to talk, smoke and watch the television news bulletin. It is an unremarkable scene – yet it is one that for many years was rarely seen in this part of Indonesia. Racked by a separatist conflict for nearly three decades, the province of Aceh, on the northern tip of Sumatra island, was a tense, fearful place. Then came the devastating tsunami of Boxing Day 2004, which injected a new urgency into long-stalled peace negotiations. Seven months later, the warring parties signed a historic agreement to end the violence.

While peace was an unexpected by-product of the tsunami, it has helped the province to recover from one of the world's worst natural disasters, while at the same time radically improving the lives of ordinary Acehnese. "You could say the tsunami was a blessing," says Azwar Hasan, head of a local NGO, Forum Bangun Aceh. "We are no longer living in fear."

No one could have predicted that the giant waves that destroyed entire towns and villages, killing more than 160,000 people and leaving half a million homeless, would transform the political landscape so thoroughly. But the provincial governor who will preside over the sober ceremony next Saturday to mark the fifth anniversary of the disaster is a former rebel commander, Irwandi Yusuf, and ex-combatants also wield power as district leaders and local representatives in the Indonesian parliament.

Equally, no one who visited Aceh just after the tsunami, which was triggered by a huge, 9.3-magnitude underwater earthquake, would have believed it possible for the place to be rebuilt so quickly from scratch. While 13 countries bordering the Indian Ocean were affected, the province – barely 100 miles from the epicentre – was ground zero, and a 500-mile stretch of the densely populated west coast, extending nearly two miles inland, was flattened.

Banda Aceh, the bustling capital, is unrecognisable from five years ago, when it was a grim, silent wasteland, its streets piled high with the debris of smashed buildings and washed by fetid floodwaters. Now, thanks largely to $.6.7bn (£4.1bn) of foreign aid, the city is a sea of spanking new houses, schools, clinics, mosques, markets and streets.

While there are reminders of the tragedy everywhere, in the memorials, peace parks and mass graves, as well as in the sad eyes of survivors, the dreadful stench of death that hung over the devoutly Muslim province has gone. The air is no longer pierced by grief; instead, there is commerce, laughter and a sense of normality.

Normality was absent even before the tsunami struck. The streets were deserted in the evening, and people avoided each other's eyes, unsure whom they could trust, fearing a knock on the door in the middle of the night. Indonesian security forces, notorious for their brutality and corruption, maintained a heavy presence, while the Free Aceh Movement (GAM), which engaged in extortion and intimidation, inspired almost equal dread.

Now GAM fighters have handed in their weapons and rejoined civil society, and the military is almost invisible, in coastal areas at least. Meanwhile, the province, which was virtually closed to outsiders during the civil war, is bidding farewell to thousands of international aid workers who took part in the remarkable reconstruction effort, one of the biggest ever undertaken. Nearly 500 overseas agencies were involved in building 140,000 new houses, 1,700 schools, 996 government buildings, 36 airports and seaports, 3,800 mosques, 363 bridges and more than 23,000 miles of road. But the statistics only tell part of the story, for in parallel with the physical restoration of Aceh, people have slowly been recovering from the trauma of losing everything: home, village, community, livelihood and numerous close relatives.

The 2004 earthquake punched a hole in the wall of the Banda Aceh prison holding Irwandi Yusuf and 286 fellow GAM members. Three days later, GAM announced a ceasefire, and in August 2005, following talks mediated by Finland's former president, Martti Ahtisaari, a peace deal was reached, which, among other things, allowed for the establishment of local political parties and guaranteed the province the lion's share of revenue from its vast natural resources. In February 2007 Mr Irwandi was sworn in as Aceh's first democratically elected governor. The transition to peace has not been entirely smooth. It has been difficult to find work for thousands of former guerrilla fighters, some of whom, underemployed and frustrated, have turned to crime. "They only know how to use a Kalashnikov, so what do you put in their hands to enable them to make a living in peacetime?" asks Bobby Anderson, co-ordinator of the International Organisation for Migration's post-conflict reintegration programme.

A government agency, the Aceh Reintegration Board, was set up to allocate cash grants and housing to former rebels. Among its employees is Kacut, an ex-combatant who has exchanged her automatic weapon for a computer. This serious young woman, who wears lipstick and an Islamic headscarf, has no regrets about her involvement with GAM, which she joined at 18, following in the footsteps of her grandfather, father and brother. "I joined because my father's nephew and other relatives had been tortured by Indonesian military forces," she says. "It was a difficult life, but there was no choice, and it was difficult for all Acehnese at that time. However bad things were, I never thought of giving up."

While she is happy with her new life, some ex-rebels remain dissatisfied, believing that the peace agreement did not go far enough. Saifdul Helmi, who spent 18 months in prison, where he was subjected to water torture and electric shocks, says: "The goal of our fighting was to gain independence for Aceh, and we haven't achieved that." There is resentment, too, that villages in the Acehnese hinterland, ravaged by decades of civil war, have received relatively little assistance. Craig Thorburn, an Australian academic who has closely studied the recovery process in Aceh, says: "The resources available for post-conflict reconstruction are minuscule, while tsunami-affected areas have had plenty of aid."

Many tsunami survivors, meanwhile, received substandard housing because contracts were awarded to former GAM commanders, according to Mr Thorburn. "They got their peace dividend, but a lot of houses were built with shoddy materials, and people were afraid to complain," he says. Almost everyone has been rehoused, though, and the extraordinarily resilient Acehnese are getting on with their lives. In the coastal village of Gampung Dayah Teungoh, children race their bicycles around the freshly paved streets, while young men sit on the beach, gazing out to sea. A woman washes her wailing toddler under a tap.

Most of Gampung Dayah Teungoh's population was wiped out in the disaster. The 119 survivors include Nurhanifah, 47. She says: "It's much quieter than before. But we try to forget the tragedy and the trauma by working and keeping active." Razali lost his wife, three daughters and six grandchildren. His house was destroyed; all that was left of the village was one tall coconut tree and the tiled floor of the mosque. "You don't want to see how bad it was then," he says. "It was so sad."

Now life is slowly improving. "After five years, we're finally getting back our community spirit, because people are moving into the village and it has come back to life," Razali says. "We have a mosque to go to; we have sanitation to wash our clothes; we have the village atmosphere. But the feeling of sadness never disappears."

Paradise lost?

COP15 Copenhagen, Michael von Bülow, 20/03/2009 12:40


Most people know the Maldives as a tropical paradise for holiday makers. But behind the white beaches and glittering waves is a poor population which has lived in close symbiosis with the sea for hundreds of years - but now has to look elsewhere for a place to live, as the ocean is steadily eating away at their islands.

When the tsunami hit the archipelago of the Maldives in 2004, it was more in the way of a flooding than a regular tidal wave due to the sharp profile of the atolls. Only 87 people perished, but the damages were catastrophic for the tiny island state.

Two thirds of the country disappeared momentarily into the Indian Ocean, and when the sea withdrew, it took 62 percent of the country’s GNP with it. Electricity, communications and freshwater supplies on many islands were destroyed by the saltwater, and not until two years later was the country brought back on foot with the aid of the UN and international aid organisations.

Perhaps it was only a taste of what the 300,000 citizens of the Maldives can expect if and when global warming kicks in and makes the world’s seas rise by as much as one meter within the next century, like the latest scientific studies forecast.

80 percent of the island state’s only 235 km2 are less than one meter above sea level, so disaster is looming. Erosion is constantly eating away at the vulnerable atolls, and climate change is already palpable in the shape of more rain and more disease-carrying mosquitoes.

To most foreigners the Maldives are just a paradise for holiday makers. White beaches as if taken straight from a postcard and a temperature that due to cooling breezes from the sea never becomes unbearably high, making the country a rare pearl made for sailing, surfing, diving or just lazing on the beach. Under the sea, hobby divers encounter a world of adventures with corals and a thousand different tropical fish species.

Almost 700.000 tourists from mainly Europe, Japan, China and Australia visit the Maldives each year. Upon landing in one of the two international airports, one immediately notices the proximity of the sea. It feels literally like landing on the water because the islands are so tiny – a jogger can easily cover the perimeter of the main island Male’ in less than half an hour. The runways are regularly wet with splashes of sea water, in spite of the fact that the airport island Hulhumale has been raised artificially to the breath-taking elevation of two meters above sea level.

With a share of 35-40 percent of the GNP, tourism is a vital source of income for the Maldives. The second largest source of income is tuna fishing, which is done with hook and line in the traditional, environmentally friendly way, but which is declining rapidly due to dwindling fish stock. Apart from that, there is some farming, consisting mostly of coconuts and papaya.

Historically, the Maldives have for hundreds of years been a crossroads for different trade routes, and this is reflected in the population which ethnically and culturally is a unique amalgamation of Indians, Africans and Arabs. In addition to that, the island state has its own written language.

But the citizens in the 100 percent Muslim country are poor, and with a national economy the size of a small European city the Maldives are totally dependant upon foreign aid and loans if the tropical paradise is to be saved from slipping away into the expansive ocean.

Who will provide the necessary hundreds of millions of dollars, and is it worth the trouble in the first place? Couldn’t the tourists just go somewhere else for their holidays and the Maldivian population move some place where the risk of getting their feet wet is less imminent?

“It is a tiny nation, and by then (2100, ed. note) the population will perhaps be half a million people who could theoretically be displaced. But can we accept the disappearance of a country and an absolutely unique culture? That is the question we need to ask ourselves,” says Jonas Kjær.

Following the tsunami, from spring 2005 till late 2007 the Dane was stationed in the Maldives by the UNDP as aid coordination advisor, aiding the Maldivian government with the economic rehabilitation. There is no doubt in his mind as to the answer.

“No, we can not accept that a country just disappears,” he says.

According to Jonas Kjær, the recipe for saving the Maldives is “population and development consolidation”. The first step would be to gather the population of the Maldives, which at the moment is scattered over 200 islands, on just 10 to 15 islands. This would at the same time make an additional number of islands available to tourists, thereby making them co-finance the relocation and rehabilitation of the local population.

The next step would be to elevate the islands artificially by two to three meters, and to build solid walls along the coast safeguarding the islands against the tide and storms.

“Of course, there are some social, cultural and historical considerations to be made. You don’t just move a population that has inhabited the islands for maybe 2,000 years. That takes political guts,” says Jonas Kjær.

In fact, population and development consolidation, nicknamed “pop concert”, has been sitting in a drawer with the previous government for at least 10 years. Due to political reluctance and fear of the population’s reaction the programme hasn’t been initiated. There seems, however, to be a growing understanding amongst the population for a need to do something – an understanding that has been augmented substantially by the impact of the tsunami.

The younger and more informed citizens have especially acknowledged the need to move, and some are already on their way. More and more young Maldivians go to Australia, New Zealand, Indonesia, Singapore, the US or the UK to study, and after finishing their studies some of them decide to stay in their new country, adding to the brain drain of their native country.

This leaves a Maldivian population, which after 30 years of semi-dictatorial rule has embarked on a positive democratic development, to hope that paradise has not already been lost.

Indonesia on alert for tsunami drill

BBC News, by Karishma Vaswani, Jakarta


Indonesians are still reeling from the devastating 7.6-magnitude earthquake which struck off the coast of Sumatra last month, killing at least 1,100 people and injuring many more.

However, as efforts shift from rescuing survivors to rebuilding the provincial capital, Padang, and outlying villages, some people have already begun to discuss whether the country is sufficiently prepared for another natural disaster.

Now a tsunami drill being held on Wednesday in 18 countries around the Indian Ocean rim aims to test the responses of local authorities and the public.

Experts are agreed that another powerful earthquake could hit the area anytime in the near future.

But they are unsure if the Indonesian emergency response teams are equipped to react quickly and effectively to a crisis on a similar scale.

The country's National Disaster Management Agency has acknowledged that it was too slow to respond to the Sumatra earthquake, which brought down hospitals, schools and shopping malls, cut power lines and triggered landslides.

"On the first day, it was just pure panic," Priyo Kardono, a spokesman for the agency, told the BBC.

"We couldn't contact our colleagues in Padang because they were affected by the disaster. It's human nature to save your family first in these circumstances. But everyone needs to evaluate their readiness and response to emergencies like these," he added.

Public response

The panic in Padang saw the city's airport closed for 12 crucial hours - an important window during which the authorities could have sent much-needed emergency rescue and relief teams to the area.

In 2004, the only warning most people had was the sight of a giant wave

The head of the Indonesian Seismological Agency, Fauzi, says that was because many of the airport workers rushed home to check on their families.

"Padang airport was abandoned shortly after the earthquake, because the workers were scared," he adds. "We urgently need systems in place to test the public's response to disasters like this, to see how they will react."

Garnering information about the responses of both the authorities and the public is one of the aims of Wednesday's tsunami drill.

Exercise Indian Ocean Wave 09 will simulate the 9.2-magnitude earthquake which struck off the north-western coast of Sumatra in 2004, triggering a tsunami that killed more than 200,000 people in 11 countries, more than half of them in the Indonesian province of Aceh.

Held on World Disaster Reduction Day, the exercise will be the first ocean-wide test of the Indian Ocean Tsunami Warning and Mitigation System (IOTWS), set up by the United Nations Educational, Scientific and Cultural Organisation (Unesco) the following year.

When the tsunami struck five years ago, the only warning most people in the region had was the sight of a giant wave heading towards them.

Unlike the Pacific, the Indian Ocean did not have a system to alert residents of coastal areas that a tsunami was imminent.

Shortly after last month's earthquake in Sumatra, an alert was quickly broadcast warning people in low-lying coastal areas of the possibility of another tsunami and ordering them to evacuate to higher ground. It was eventually lifted, however, as a tsunami did not materialise.

Vital co-operation

Unesco is helping to organise Wednesday's tsunami exercise. According to the UN agency, it will be the first time that the IOTWS will be tested worldwide.


Spokeswoman Sue Williams says one of the major challenges has been to get all the countries who signed up to the system to share data.

"The countries have to share their data otherwise this system won't work," she explains.

"If a tsunami is generated off the coast of Indonesia and is on its way to Africa - then African authorities need to have data about the wave at the source, where it began its journey. That means sharing seismic data and maps - and that was a very important part of the discussions and negotiations we had before we signed this agreement."

Another major challenge is getting the information about a potential tsunami out to people in the coastal areas, Ms Williams says.

"The instruments that are used to measure seismic activity and tsunami activity are in the water - the thing to watch is what happens on the beach," she adds.

"We've seen that national authorities can get the message out about a potential tsunami very quickly, but getting the message out to the communities on the coast is a completely different challenge."

"If the fault line of the earthquake is very close to the coast - the way it was in Aceh - then people have only got a few minutes to act," she warns.

Equipment shortage

The Indonesian government wants to deliver tsunami alerts to its citizens and those most at risk from the destructive wave within five minutes of an underwater earthquake in the region.

But experts say that will not be achieved until the country has installed at least 22 buoys, 120 tide gauges and 160 seismographs in its waters.

So far, according to the Indonesian Seismological Agency, it only has 14 buoys, 60 tide gauges and 150 seismographs.

The system is expected to be fully completed by 2010, but is already operational. Much of the funding for it has come from international donors, including Germany, Japan and China.

Wednesday's test will therefore determine whether the Indonesian authorities have spent that money wisely, and whether people are prepared for another catastrophe.
