The recent earthquake in Nepal was
about magnitude 7.8 which is similar to having 20 thermonuclear hydrogen
bombs – each many times greater than the atomic bomb that devastated
Hiroshima – ripping through the Kathmandu Valley.
Before we proceed further on the cause
it is important to understand what is going on inside the earth crust
which is causing the movement. You might not know but earth is
constantly changing and all the continents are moving. This happens
because of the tectonic plates below them. Have a look on the following
video to understand this properly.
The India tectonic plate moving north
at about 45mm a year is pushing under the Eurasian plate beneath the
Himalayas. Two tectonic plates meet beneath the Himalayas along a fault
line. The India plate is moving north at around 45mm a year and pushing
under the Eurasian plate. Over time that is how the Himalayas were
created. Dr Brian Baptie, head of
seismology at the British Geological Survey in Edinburgh, explains the
potential after-effects of the quake. Saturday’s catastrophic earthquake
in Nepal occurred because of two converging tectonic plates: the India
plate and the overriding Eurasia plate to the north, the U.S. Geological
Survey said.
