in frequent seismic activity
Several aftershocks following the main earthquake
Impacts:

Primary ­
309 people were killed and over 1'600 injured
Thousands of building were…

9.1 magnitude earthquake

Destructive plate margin ­ Indo ­ Australian (oceanic) plate subducting underneath the Eurasian
plate (continental)


Causes:

around 746 miles of plate suddenly shifting
The uplift caused the…
