DEATHQUAKE;
WHERE NEXT
India's
Seismic Highways
The
colliding Indian and Eurasian plates have made the subcontinent one of
the world's most active earthquake zones
TITANIC
TECTONICS
The Indian continental plate is pushing into and under the Eurasian plate
at the rate of 5 cm a year. This has, over time, formed the Himalayas.
As a result of this continuous movement, shock waves ripple across the
subcontinent. When the waves reach a fault, the energy is released causing
the faults to shift.
MAJOR
FAULT ZONES
Faults criss-cross the Indian subcontinent like sutures on a patient.
Regions along these fault lines are vulnerable to quakes.
SHIFTY
MOVEMENTS
1- Depending on the direction of the force, the two surfaces of
a fault may move in a vertical direction in an earthquake. This is called
a "dip-slip" fault.
2-
If the force is greater in a parallel direction the two surfaces of the
fault slide past each other laterally. This movement generates most of
the world's earthquake.
