Scientists convened in
Kathmandu to figure out how to plan for disaster in overcrowded city just days
before devastating temblor
Nepal’s
devastating earthquake was the disaster experts knew was coming.
Just a
week ago, about 50 earthquake and social scientists from around the world came
to Kathmandu, Nepal, to figure out how to get this poor, congested,
overdeveloped, shoddily built area to prepare better for the big one, a repeat
of the 1934 temblor that leveled this city.
They knew
they were racing the clock, but they didn’t know when what they feared would
strike.
“It was sort of a
nightmare waiting to happen,” said seismologist James Jackson, head of the
earth sciences department at the University of Cambridge in England.
“Physically and geologically what happened is exactly what we thought would
happen.”
But he didn’t expect the
massive quake that struck Saturday to happen so soon.
The magnitude 7.8
earthquake killed nearly 1,400 and counting and caused widespread destruction.
“I was walking through
that very area where that earthquake was and I thought at the very time that
the area was heading for trouble,” said Jackson, lead scientist for Earthquakes
Without Frontiers, a group that tries to make Asia more able to bounce back
from these disasters and was having the meeting.
A Kathmandu earthquake has
long been feared, not just because of the natural seismic fault, but because of
the local, more human conditions that make it worse.
The same size shaking can
have bigger effects on different parts of the globe because of building
construction and population and that’s something the US Geological Survey
calculates ahead of time.
So the same level of
severe shaking would cause 10 to 30 people to die per million residents in
California, but 1,000 maybe more in Nepal, and up to 10,000 in parts of
Pakistan, India, Iran and China, said USGS seismologist David Wald.
While the trigger of the disaster
is natural — an earthquake — “the consequences are very much man-made,” Jackson
said. Except for landslides, which in this case are a serious problem, “it’s
buildings that kill people, not earthquakes,” Jackson said. If you lived in a
flat desert with no water, an earthquake wouldn’t harm you, but then few people
want to live there.
“The real problem in Asia
is how people have concentrated in dangerous places,” Jackson said.
Kathmandu was warned,
first by the Earth itself: this is the fifth significant quake there in the
last 205 years, including the massive 1934 one.
“They knew they had a
problem but it was so large they didn’t where to start, how to start,” said
Hari Ghi, southeast Asia regional coordinator for Geohazards International, a
group that works on worldwide quake risks. Ghi, Jackson and Wald said Nepal was
making progress on reducing its vulnerability to earthquakes, but not quickly
or big enough.
