T he Earthquake
Jan 26 2001 [8.46am]
Epicenter – 23.6 North Latitude and 69.8 East Longitude (village called Bhuj)
The Quake spread over 200kms radius and stretched to cities that was seven hours ride.

How Tectonic plates released pressure in the area after a collision margin.
Collision margin – two continental plates hit into each other and begin to rub creating lots The earthquake was considered as intraplate earthquake.
Intraplate earthquake – earthquake within plates which occur at fault zones in the middles of the plate.
Most of the cases, the causative fault in intraplate earthquake is deeply buried, and sometimes hard to be found. So, it was hard to calculate the exact seismic hazard for a given city.
Intraplate earthquake also occur in great distance from any plate boundary.
In conclusion, the area was not completely prepared causing terrible devastation. About 19,000 people died
150,000 people were injured.
90% home in Bhuj was destroyed.
Over a million structures were
damaged or destroyed.
$5.5 billion property damaged. Significant changes
Significant Ocean parameters Surface
Surface Land and ocean Atmospheric A big tentional crack (~ 30 cm deep) in a nearby field on Bhuj
Salt water has come up to the surface through the crack due to liquefaction. Huge crater like openings developed near Lodai Village. There was a lot of expulsion
of brackish water from these holes, which on drying has led to the formation layers of salt. Impact on:
Building of cooperatives
Animals Picture of the dried out shrubs and trees due to the intense
shaking generated during the earthquake. Dextral type displacement in a bridge. Poverty became unbearable
