2. What is an earthquake:
Earthquakes can be extremely
violent or so slight that they only
register on instruments. They are
caused by sudden movements of the
Earth's tectonic plates. The study of
earthquakes is called seismology. ...
The magnitude of an earthquake,
and the intensity of shaking, is
usually reported on the Richter scale.

4. How it is produced?
1.When two plates collide, a large amount of energy accumulates. And when that
energy is released the earthquake occurs. The energy is released in the form of
waves, which shakes the surface of the Earth.
