The death toll from Indonesia's tsunami has soared to at least 343
with 370 others missing, as questions mount over whether an elaborate
tsunami warning system off the country's western coast had failed.
Susilo Bambang Yudhoyono, Indonesia's president, headed on Thursday
to the disaster zone, where fears were growing for hundreds still
missing following Monday's tsunami.
Three-metre high waves
triggered by a powerful earthquake hit the Mentawais, a small group of
islands 280km to the northwest of Sumatra, on Monday.
Disaster response officials said bodies were still being found on
beaches and coastal areas in the Mentawais, which took the full force of
the tsunami as it washed away entire villages.
The National Disaster Mitigation Agency said on its website that 4,000 people had been displaced.
Al Jazeera's Wayne Hay, reporting from Sikakap on South Pagai
island, said official government death toll figures are slightly lower
that what local media are reporting.
Broken alarm system
As the magnitude of the disaster became clear, many began asking
whether an expensive warning system - established after the massive 2004
Asian tsunami, which killed at least 168,000 people in Indonesia alone -
Tsunami survivors have said they had almost no warning that the wall
of water was bearing down on them, despite a sophisticated network of
alarm buoys off the Sumatran coast.
While an official tsunami
warning was apparently issued just after the 7.7-magnitude quake, it
either came too late or did not reach the communities in most danger.
"There are suggestions that in fact the [early warning system] has never worked properly since 2004," our correspondent said.
survivor, Borinte, a 32-year-old farmer, said the wave slammed into his
community on North Pagai island only 10 minutes after residents had
felt the quake.
"About 10 minutes after the quake we heard a loud, thunderous sound.
We went outside and saw the wave coming. We tried to run away to higher
ground but the wave was much quicker than us," he told the AFP news
agency on Wednesday.
He said he managed to stay alive by clasping to a piece of wood. His wife and three children were killed.
Dealing with disaster
The United States and several of Indonesia's neighbours have pledged
help for a nation which often finds itself battling calamity, although
Jakarta said it did not see a need for foreign assistance.
Barack Obama, the US president, lived in Indonesia as a boy and is
due to return there on an Asian tour next month. Obama voiced his
sadness over the deaths and pledged US help.
The Vatican also made appeals for international aid.
Meanwhile, Indonesian vice-president Boediono visited Munte Baru-Baru
village, the hardest hit village on Pagai Island, where 88 bodies have
Indonesia straddles a region where the meeting of continental plates
causes high seismic activity. It has the world's largest number of
active volcanoes and is shaken by thousands of earthquakes every year.
A 7.6-magnitude earthquake last year in Padang killed about 1,100
people, triggered by a 9.3-magnitude quake along the same fault
line that caused the 2004 Asian tsunami.
