Moscow (ANTARA News/RIA Novosti-OANA) - The Japanese authorities say 1,000 dead bodies scattered around Japan`s troubled Fukushima power plant are too radioactive for emergency workers to collect, Kyodo news agency reported on Friday.

The bodies of those killed in devastating earthquake and tsunami that swept the region in mid-March were contaminated when radiation began leaking from the damaged reactors at the plant.

"After people died their bodies were exposed to high levels of radiation," a police source said.

Experts partially confirmed the information, saying they had found high radiation levels in a body found in the village of Okuma, five kilometers from the power plant.

Police warned that collecting the bodies would spread contamination outside of the evacuation zone, set at 20 kilometers.Over 11,000 people died and 16,500 are still missing from the twin disaster.

A teenager rescued from the rubble of Japan’s monster earthquake in a rare feat of survival recounted on Monday spending nine days trapped inside the wreckage unable to alert rescuers outside.

Jin Abe and his 80-year-old grandmother Sumi Abe were in the kitchen on the top floor of a two-storey wooden house when the 9.0-magnitude tremor struck on March 11, unleashing a massive tsunami that flattened entire cities.

The building collapsed with both inside but the 16-year-old was able to reach blankets, food and drink, helping them survive for more than a week, huddled together to keep warm.

“We found some water and snacks, so we ate them,” he said on Monday from his hospital bed in the devastated coastal city of Ishinomaki in Miyagi prefecture.

“We heard people outside but we couldn’t escape,” he said in a frail voice.

The teen described being confined in a space “the size of a room,” unable to stand up or walk around.

Finally on Sunday he managed to claw through the rubble and call out to rescue teams combing the earthquake and tsunami zone, and was airlifted to hospital along with his grandmother.

“I’m glad we survived,” he said.

The boy’s father Akira said he never gave up hope of seeing his son again.

“We all believed they were alive somewhere,” he said. “He doesn’t talk much, but I always thought he was a great man. This time he really proved it.”

The tale of endurance offered a glimmer of hope for the relatives of other people still missing after the twin natural disaster.

“I feel stunned that the two people survived in really difficult conditions for such a long time. This miraculous news is very encouraging for people affected by the disasters,” said government spokesman Yukio Edano.

But freezing temperatures in the disaster zone have dimmed hopes of finding more survivors.

Troops announced on Saturday they had found a man thought to have spent eight days in a half-destroyed house, but it later turned out he was actually an evacuee who had simply returned to his home.

MOX plutonium fuel used in Fukushima's Unit 3 reactor two million times more deadly than enriched uranium

Natural News, Thursday, March 17, 2011 by: Ethan A. Huff, staff writer

(NaturalNews) Largely absent from most mainstream media reports on the Fukushima Daiichi nuclear disaster is the fact that a highly-dangerous "mixed-oxide" (MOX) fuel in present in six percent of the fuel rods at the plant's Unit 3 reactor. Why is MOX a big deal? According to the Nuclear Information Resource Center (NIRS), this plutonium-uranium fuel mixture is far more dangerous than typical enriched uranium -- a single milligram (mg) of MOX is as deadly as 2,000,000 mg of normal enriched uranium.

On March 14, Unit 3 of the Fukushima reactor exploded, sending a huge smoke plume into the air. This particular reactor, of course, contains the rods fueled with MOX. You can watch a clip of that explosion here: http://www.youtube.com/watch ....

If even a couple milligrams of MOX were released during this explosion -- or if other explosions at the plant inflict any damage on the MOX-filled rods -- then the consequences could be exponentially more devastating than the mere leakage of enriched uranium. And since nobody knows for sure exactly which rods have been damaged, and whether or not the situation can actually be contained, it is only a matter of time before the world finds out for sure.

An exact quote from the report reads:

"In the event of such accidents (involving the accidental release of MOX), if the ICRP (International Commission on Radiological Protection) recommendations for general public exposure were adhered to, only about one mg of plutonium may be released from a MOX facility to the environment. As a comparison, in [sic] uranium fabrication facility, 2kg (2,000,000 mg) of uranium could be released in the same radiation exposure."

A simple calculation reveals that one mg of MOX is basically two million times more powerful than one mg of uranium. This is clearly not a good thing when the plutonium-containing fuel rods in Fukushima may be damaged from the recent explosions and leaking into the environment.

A recent National Public Radio (NPR) piece explains that the half-life of plutonium-239, a component of MOX, is an astounding 24,000 years. The same piece explains that if even a small amount of this potent substance escapes from the plant in a smoke plume, the particles will travel with the wind and contaminate soil for tens of thousands of years (http://www.npr.org/2011/03 ...).

Amazingly, most mainstream reports that mention MOX discount it as a non-threat. But the truth of the matter is that the threat posed by MOX is very serious. The NIRS report explains that inhalation of MOX radioactive material is significantly more dangerous than inhalation of normal uranium radioactive particles. You can read the entire MOX report for yourself here:

Indonesian Survives His Second Tsunami

The Jakarta Globe, March 15, 2011

Indonesian Zahrul Fuadi has twice survived tsunamis  — once, in his hometown in Aceh in 2004 and then again in Sendai, Japan, last Friday.

The 39-year-old is among Indonesians evacuated from Sendai, one of the worst-hit areas affected by Friday's 4-meter tsunami.

“I feel as if my family and I are being chased by tsunamis from Aceh to Japan,” Zahrul said, as quoted by news portal Kompas.com.

When the tsunami wreaked havoc on Aceh on Dec. 26, 2004, Zahrul and has family were spared their lives.

“After the quake in 2004, we escaped on a motorbike as fast as possible and we made it,” he said, adding that his house in Simpang Mesra village, Banda Aceh, was destroyed in the disaster.

Zahrul, a professor of engineering at Syah Kuala University, and his family moved to Sendai the following year after he received a scholarship to complete a PhD at Tohoko University.

“I have lived here for six years and I had planned to return to Aceh, but as fate would have it, I endured another huge earthquake before coming home,” he said.

When the 8.9-magnitude earthquake struck off the northeastern coast of Japan, Zahrul was in the middle of a presentation at the Sendai campus.

“The tremor was so intense, everyone hid under their desks,” he said.

As the tremor continued for longer than two minutes, Zahrul knew the worst was yet to come.

“The tremor was very strong and similar to the earthquake in Aceh. I thought a tsunami was on the way,” he said.

He and his family were spared the second time because the campus is located 15 kilometers from the coast on high land.

Zahrul was staying at the Indonesian evacuation center in Tokyo and was scheduled to fly home to Indonesia on Tuesday.

“Despite what has happened, my family and I have so much to thank God for. We have survived two of the biggest natural disasters recorded in history,” he said.

Tsunami-hit Mentawai in need of medicine, health workers

The Jakarta Post, Thu, 01/20/2011

More than two months after the tsunami struck Mentawai Islands, many victims are in desperate need of medicine and health workers, a humanitarian worker says.

Health Project manager of Mitra Peduli Mentawai Dr. Louisa A. Langi said that at least 134 people in evacuation camps on Siberut Island suffered from various illnesses such as diarrhea, fever and acute respiratory problems, kompas.com reported Thursday.

Many people were evacuated to Siberut Island as the area was relatively not affected by the devastating tsunami, which swept parts of Sipora, Pagai Utara and Pagai Selatan islands, last Oct. 25.

The lack of medicine was alarming, Louisa said, adding that even paracetamol was not available.

She called upon the government to pay more attention to the evacuees, especially those suffering from illnesses.

Head of the provincial disaster management agency Hermensyah said Wednesday that the budget was allocated only for victims who were directly affected by the disaster. As for the medicine shortage, Hermensyah said the problem could be settled with continuing funds from third parties.

Govt to bear tsunami victims` living cost

Antara News, Friday, December 3, 2010

Padang, W Sumatra (ANTARA News) - The government plans to bear the living cost of tsunami victims in the Mentawai Islands until the rehabilitation and reconstruction efforts have been completed, an official said.

"The living cost of each tsunami victim has been projected to reach Rp6,000 per day. The maximum number of people in each family entitled to receive such assistance is five. The government will bear the living cost of tsunami victims for one month," Head of the West Sumatra Provincial Social Service Kafrawi said on Thursday.

The government will start bearing the living cost of tsunami victims as of early January 2011, he said adding the local authorities are in the middle of registering recipients of such assistance.

"We ask the Mentawai district administration to send a list of recipients to the West Sumatra governor as soon as possible so that we can quickly pass it on to the Social Service Ministry," he said on the sidelines of a meeting between West Sumatra

Governor Irwan Prayitno and Indonesian Red Cross (PMI) Chairman Jusuf Kalla here.
He said his office recently held a meeting with the Social Service to discuss the living cost and the ministry had given the green light to bear the living cost of tsunami victims.

"We hope the plan can be realized according to the schedule so it can alleviate the economic burden of the tsunami victims in the islands," he said.

The National Disaster Management Agency (BNPB) stated the big earthquake followed by a tsunami in Mentawai Islands had affected a large number of villages and caused 408 deaths, 303 people to go missing and 270 others to sustain severe injuries.

The number of affected people was initially estimated at 33,817. However, many islands had become inaccessible and the number of potentially affected people could be over 65,000.

Official Proposes Disaster Education in Schools

Jakarta Globe, November 12, 2010

Jakarta. The government needs to make education about natural disasters part of the school curriculum, an official said on Friday.

after hearing about the deaths of family members following the
tsunami on Oct. 25. Officials said that education can help reduce
casualties when calamities strike. (Antara Photo)
"Including knowledge about natural disasters in the school curriculum is one way to help reduce casualties when a disaster strikes," said Safri Baharuddin, chief of information at the Coordinating Ministry for People's Welfare.

He said that many Indonesians did not know what to do in the event of natural disasters, like earthquakes or tsunamis. This often adds to panic during such situations.

"People, especially those living in disaster-prone areas, must be taught what they must do during a disaster. Conducting disaster drills may help, but such exercises are not regularly done," Safri said.

He added that 1uake-proof buildings should also be enforced. "BMKG [The Meteorology, Climatology and Geophysics Agency] and the Ministry of Public Works have created a model of a seismic-proof buildings. I suggest that developers, especially those who want to build housing complexes near disaster-prone areas, use the system," he said.

To try to reduce the number of casualties in the event of natural disasters, the National Disaster Management Agency (BNPB) had earlier announced that it would allocate Rp 100 million ($11,200) in 2011 for the mapping of disaster-prone areas in Indonesia.
"The map is needed to support local governments' efforts to daw up maps of the vulnerable areas. These areas must not be used for housing development or construction of public places," said Sutopo Purwo Nugroho, BNPB's director of Disaster Risk Reduction.
He added that the funds would be distributed equally among BNPB's office in 33 provinces to support the mapping work.

Sutopo expressed hope that the mapping of disaster-prone areas in Indonesia could help the government reduce the number of casualties due to natural disasters.

Indonesia is one of the most disaster-prone countries in the world because it is located on the Pacific Ocean's “Ring of Fire” of volcanoes and earthquakes.

Last month, Indonesia was hit by three major disasters in different parts of the country. The first one was a flash flood in Wasior, West Papua, on Oct. 3 that left 124 people dead and 123 others missing.

The second disaster was an earthquake with a magnitude of 7.7, which was followed by a tsunami in the Mentawai Islands, West Sumatra, on Oct. 25. At least 408 people were killed, 303 others missing and 23,000 displaced.

Just one day after the Mentawai earthquake and tsunami, Mount Merapi, one of Indonesia's most active volcanoes, started to erupt on Oct. 26.

Are You Ready for Indonesia's Disasters?

Jakarta Globe, Ade Mardiyati | November 04, 2010

On the fateful morning of Dec. 26, 2004, Nurhasimah, also known as Ima, felt an earthquake in Tamiang, a district in eastern Aceh close to North Sumatra. Ima, who moved there to work as a teacher, thought the quake’s epicenter was in the North Sumatra capital, Medan. She had no inkling of the tragedy befalling members of her family in other parts of Aceh.

“Later on, I saw on TV that [the quake’s epicenter was not in Medan], and that a tsunami had struck North Aceh where my father and siblings lived. Then my uncle told me that Banda Aceh, where my grandmother and other relatives lived, had suffered the same fate,” she said.

“I immediately tried to contact them but was unable to get through because communication was already cut off.”

In the evening, she learned that her father and siblings had survived the disaster. But her grandmother, aunts, uncles and cousins were missing. Their bodies were never found.

“I felt faint and became sick. I went to the doctor and found out that my blood pressure had dropped to just 120/70,” she said. “I was stressed out and traumatized.”

Ima said that she was familiar with minor earthquakes caused by the rumbling of Mount Seulawah in Aceh, but could never have imagined a disaster the magnitude of the Indian Ocean tsunami, which killed more than 100,000 people in the province.

“There was never any information or training about disasters or what to do when they happen,” she said.

“Not until the tsunami hit the province and claimed the lives of so many people did the local government start offering such things.”

Since the 2004 disaster, the Acehnese have become more aware and better informed about what to do in the event of another disaster.

Ima said that many families in the province now keep emergency bags ready in their homes, which contain clothes and important documents.

“Just in case something happens, you can just grab it and leave the house,” she said.

While most Indonesians are aware that they live in a country where natural disasters such as earthquakes, tsunamis and volcanic eruptions are a frequent risk, most people not really know what to do when they happen.

Hery Prakoso, who drives a cab in Jakarta for a living, said he was not prepared and would likely be at a loss for what to do if a natural disaster struck the capital.

“All I know is that I would save my wife and son first and take the suitcase that I keep all the important documents in with me,” the 47-year-old said.

“But where to go, I have no idea. Maybe to higher ground, but I’m not sure where that is in Jakarta.”

Andrew Revindo, a 19-year-old university student in Jakarta, shared Hery’s confusion. “I know I should get out of the building if there is an earthquake. But if a tsunami comes, I would have no idea what to do,” he said.

Gagah Prakoso, from the National Search and Rescue Agency (Basarnas), said that Indonesians were not prepared to deal with emergency situations.

“There needs to be a concerted effort to education people about what to do in the event of a disaster, no matter how small it is,” he said.

He gave the example of what happened in the remote town of Wasior, in West Papua, which was devastated after flash floods and landslides tore through the area on Oct. 4.

At least 161 people have been confirmed dead, another 145 are missing and presumed dead, and thousands more were displaced from their homes.

“All the displaced people living in tents in Wasior did was eat and sleep,” he said.

“They could have been potential resources to help around the shelter and they would have known better because [Wasior] was their home. But they didn’t know what else to do because they had not been briefed on what to do.”

Ima believes that knowing how to read signs from Mother Nature is better than simply reacting to a disaster.

“Like the tsunami in Aceh. It would still have happened, but it probably wouldn’t have claimed as many lives as it did had people known the signs,” she said.

She said that she later heard how when the ocean began retreating at Ulee Lheue Beach in Banda Aceh, people went down to the shore to collect fish, failing to recognize the warning sign for an impending tsunami.

“It was not normal for the ocean to retreat like that. That was a sign of something bad, but no one knew what,” she said. “I guess that if we had been informed earlier on, we wouldn’t have lost so much.”

Fery Manuputty, who lives in Ambon, Maluku, which is surrounded by water, echoed Ima’s sentiment.

“The ability to read the signs [from Mother Nature] and knowing what to do when a natural disaster occurs are very important, especially for people who live in areas that are prone to such things,” he said.

“Earthquakes, although minor, happen frequently in Ambon, so I have learned what to do in case a strong one hits.

“The last big earthquake that was followed by a small tsunami took place in 1988 when Mount Api erupted [on Maluku’s Banda Naira Island], but you never know.”

Fery also pointed out that whenever an earthquake in Ambon took place, residents often got their information from Jakarta-based television stations.

“The local government is obviously not prepared. They have to do better than that given that earthquakes happen frequently in Maluku,” he said.

If one theme emerges, it is that people want the government to do more to make sure that its citizens know how to read the signs and then known what to do when disaster happens.

“I’m sure the government has done [information campaigns before], but it has to do a better job of it and take it more seriously. It needs to convince people that it is important to know these things,” taxi driver Hery said.

University student Andrew also wants a more thorough information campaign. “Information on disasters should not be given only on TV, as the government has mostly done in the past. Not everyone in Indonesia has access to a TV,” he said.

“The Indonesian government should take more action. Go to remote areas, talk to the people and make sure the information is out there for everyone.”


What to Do When Mother Nature Strikes

Earthquake.
  • Don’t panic. Be aware that some earthquakes are actually foreshocks and a larger earthquake might occur.
  • Minimize your movements to a nearby safe place.
  • If you are indoors, stay there until the shaking has stopped and you are sure that exiting is safe.

If indoors:
  • Drop to the ground, take cover by getting under a sturdy table or other piece of furniture and hold on until the shaking stops.
  • If there isn’t a table or desk near you, cover your face and head with your arms and crouch in an inside corner of the building.
  • Stay away from glass, windows, outside doors and walls and anything that could fall, such as lighting fixtures or furniture.
  • Use a doorway for shelter only if it is in close proximity to you and if you know it is a strongly supported, load-bearing doorway.
  • Stay inside until the shaking stops and it is safe to go outside.
  • Research has shown that most injuries occur when people inside buildings attempt to move to a different location inside the building or try to leave.
  • Be aware that the electricity may go out or the sprinkler systems or fire alarms may turn on.
  • Do not use the elevators as they might stop and strand you.

If outdoors:
  • Stay there. Move away from buildings, streetlights and utility wires.
  • The greatest danger exists directly outside buildings, at exits and alongside exterior walls.
  • Ground movement during an earthquake is seldom the direct cause of death or injury.
  • Most earthquake-related casualties result from collapsing walls, flying glass and falling objects.

If in a moving vehicle:
  • Stop as quickly as safety permits and stay in the vehicle.
  • Avoid stopping near or under buildings, trees, overpasses and utility wires.
  • Proceed cautiously once the earthquake has stopped.
  • Avoid roads, bridges or ramps that might have been damaged by the earthquake.

If trapped under debris:
  • Do not light a match.
  • Do not move about or kick up dust.
  • Cover your mouth with a handkerchief or clothing.
  • Tap on a pipe or wall so rescuers can locate you.
  • Use a whistle if one is available.
  • Shout only as a last resort. Shouting can cause you to inhale dangerous amounts of dust.


Tsunami.
  • An earthquake is a natural tsunami warning.
  • If you feel a strong quake, do not stay close to shore.
  • If you hear of an earthquake, be aware of the possibility of a tsunami and listen to the radio or television for additional information.
  • Remember that an earthquake can trigger killer waves thousands of miles across the ocean many hours after the event generated a tsunami.
  • An approaching tsunami is preceded by an unusual fall or rise in the water level.
  • If you see the ocean receding unusually rapidly, that’s a good sign that a tsunami may be on its way.
  • Go to high ground immediately.
  • A tsunami is a series of waves and the first wave may not be the most dangerous.
  • The danger from a tsunami can last for several hours after the arrival of the first wave strikes.
  • A tsunami wave train may come as a series of surges that are five minutes to an hour apart.
  • The cycle may be marked by a repeated retreat and advance of the ocean.
  • Stay out of danger until you hear it is safe.
  • Use your common sense. If you feel or hear of a strong earthquake do not wait for an official tsunami warning.
  • Tell your family and friends to join you in leaving for high ground.

Heartache for Survivors in Tsunami-Hit Indonesia

Jakarta Globe, Supri Lindra | October 28, 2010

Muntei Baru Baru, Indonesia. Exhausted, confused and hungry, 20-year-old Indonesian housewife Chandra trudged barefoot through her tsunami-wrecked village in a desperate search for her missing baby.

“I sifted through rubble, looked in collapsed houses and in the temporary shelters but there’s no sign of him,” she said, tears welling up. “I know he’s dead but I keep praying he’s still alive. I’m so tired. I’ve not eaten for two days ... I have no appetite.”

Chandra was one of the survivors after a huge wave triggered by a devastating 7.7-magnitude earthquake Monday ravaged the remote Mentawai islands off the west coast of Sumatra, killing 343 people and leaving 338 missing.

Disaster response officials said bodies were being found on beaches and coastal areas in the Mentawai island chain, which took the full force as the tsunami washed away entire villages.

Chandra said she was separated from her husband and six-month-old son as they were trying to flee the tsunami when it hit their coastal village in North Pagai island, one of the two worst-hit in the Mentawai group.

“I survived because a coconut tree fell and kept me from being swept away. My survival was a miracle from God,” she said.

Her husband’s body was found by locals and buried along with dozens of other villagers in a mass grave on Wednesday.

The tsunami had flattened their village of Muntei Baru Baru, destroying more than 70 mostly wooden houses, a school and a church. Left behind were skeletons of houses, fallen trees and a fetid mud pool.

Survivors said they had almost no warning that the three-meter wall of water was bearing down on them, raising questions about whether an early alert system laid down after the 2004 Asian tsunami had failed.

An AFP photographer who came to North Pagai aboard an aid ship saw hundreds of villagers being treated at a medical clinic, many requiring stitches to open cuts suffered as they were tossed around in the roiling sea.

Like Chandra, dozens of villagers are still trying to come to terms with the tragedy.

Many scrabbled through rubble to look for missing relatives while others, dazed by the disaster, sat under coconut trees awaiting news from rescuers.

Chandra said she did not know what the future holds.

“I’ve no intention to rebuild my house. I now live alone, I don’t know what to do,” she said.

“Whatever happens, I’m not going to leave this village. This place is the burial place for my husband and baby.”

PMI sends personnel, ambulances to Mentawai

Antara News, Tuesday, October 26, 2010 16:50 WIB

Jakarta (ANTARA News) - The Indonesian Red Cross (PMI) has mobilized tens of personnel and sent four ambulances to Mentawai for early assessment following a powerful earthquake which hit the area on Monday evening (Oct 25).

"PMI West Sumatra office has sent four ambulances and tens of personnel. For the moment, we are still waiting for complete report from the local PMI office on the situation in Mentawai," Achmad Djaelani of the Jakarta-based PMI Headquarters, said in a statement here Tuesday.

An earthquake measuring 7.2 on the Richter scale rocked Mentawai islands at 21.42 last Monday with its epicenter located 78 km west of Pagai Selatan subdistrict, Mentawai district, at a depth of 10 km below sea level.

Aftershocks continued to happen in Mentawai, West Sumatra, following the magnitude-7.2 quake . A quake measuring 5.5 on the Richter Scale followed at 10 pm at a depth of 22 kilometers, 89 kilometers southwest of Pagai Selatan.

Another quake was also recorded at 5.0 on the Richter Scale at 10.31 pm at a depth of 34 kilometers, 51 kilometers southwest of Pagai Selatan.

Meanwhile, a two-meter high tsunami struck Mentawai island following a 7.2 earthquake last Monday (Oct 25) at 21.42.

"The information about an impending tsunami was obtained from Australian volunteers who are stationed there. According to their report, they found some fishermen`s boat stranded in land," an expert of the Padang-based University of Andalas, Dr Badrul Mustapa Kemal, said here on Tuesday.

The quake was also felt by people in Padang, Kerinci, Jambi, and even up to Singapore.

On September 30, 2009, a powerful earthquake with a magnitude of 7.9 on the Richter scale devastated Padang city, the provincial capital of West Sumatra, killing at least 1,117 people.

Indonesia on Shakier Ground, Experts Warn

Jakata Globe, Nurfika Osman, March 26, 2010

Massive earthquakes over the past few years have increased the volatility of the tectonic plates beneath the archipelago, experts have warned. They have called for more quake-proof buildings to withstand the heightened threat.

“We are more at risk as the ground becomes more vulnerable and the effects of earthquakes are going to be more devastating,” Mulyo Haris Pradono of the Earthquake Engineering and Disaster Mitigation Unit at the Agency for the Assessment and Application of Technology (BPPT) said on Friday.

He was referring to peak ground acceleration, a measure of earthquake acceleration on the ground and an important calculation for earthquake engineering.

Mulyo said the PGA in the southern part of Sumatra, Java, North Sulawesi and Papua was the highest in Indonesia.

The assessment is based on research conducted in 2002 and the data is expected to be updated in 2012.

Massive quakes last year that heighten the PGA included the 7.3-magnitude temblor in West Java on Sept. 2, the 7.6-magnitude quake that rocked West Sumatra on September 30 and the 7.2 tremor in West Papua in January.

According to the National Disaster Management Agency (BNPB), there are 23 earthquake-prone provinces in the country, including Aceh, West Sumatra, West Java, East Java, Bali, West Papua and Papua.

Mulyo said that as increased ground movement was inevitable, the only solution was to build quake-proof buildings in vulnerable areas.

“We are still conducting in-depth research and are assisting West Sumatra to build safer buildings with help from Japan,” he said.

“The point is that now we have to be more aware and prepare for earthquakes.”

He said the primary challenge was the lack of public awareness and effective regulations governing safe construction as people continued to build unsafe structures because they were cheaper.

Fumihiko Imamura, from Japan’s Tohoku University, said the BPPT and Japan had surveyed collapsed buildings in Padang.

“We concluded that many mistakes occurred in the structural planning of the buildings and homes,” Imamura said.

“In order to fix this we need not only a scientific approach but also a social and cultural approach to convince people that they need to live in a safer place to reduce the hazard.”

The two countries last year established a four-year research program called Multidisciplinary Hazard Reduction from Earthquakes and Volcanoes in Indonesia, in an effort to minimize the impact of disasters.

Fourteen institutions from both nations are involved in the joint research.
