The Sichuan Earthquake - an example of an Earthquake
disaster in an LEDC
The Sichuan earthquake was a catastrophic earthquake that full
demonstrated the power that earthquakes have. It also showed how poor
building design and construction, large earthquake strength, high population
density and shallow earthquake depth can all combine to create a disaster.

Initial death tolls ran at 8,700 but this eventually rose to 69,000 with
18,000 people missing two months after the quake.
374,000 people were injured and between 5 million and 11
million people were made homeless. A total of 5 million buildings collapsed;
including a number of schools (Juyuan middle school in Dujiangyan city collapsed
killing 900 pupils). Other
impacts included that communications were brought to a
halt and the cost of restoring infrastructure was put at $75 million. Some areas
were cut off by landslides and building collapses left rubble everywhere.
In Shifang, chemical plants collapsed killing hundreds
and releasing toxic ammonia.
Power and water supplies were cut and flooding occurred
because landslides had blocked rivers.
Indeed, some areas
in Wenchuan had not been reached within 30 hours of the earthquake.
20 helicopters were assigned to rescue and relief
efforts immediately after the quake.
Troops were parachuted in to assess the situation, and
others hiked in on foot.
The army coordinated most of the relief effort.
Big efforts were made to free people trapped in
buildings, and land was flattened so that tents could be erected. One million
small temporary homes will be built to house the homeless.
The Vice governor of Sichuan hopes that the rebuilding will be complete
in 3 years.
The Chinese government pledged a $10million rebuilding fund and banks
wrote of debts of survivors who did not have insurance.
China requested
international help 2 days after the quake.
Teams from Japan, Russia and South Korea joined the
rescue effort and over £100 million had been donated to the Red Cross in the
fortnight after the quake.
Much of this went into running the camps.
