Earthquake and its causes
earthquake is a series of vibrations on the
earth's surface caused by the generation of elastic (seismic)
waves due to sudden rupture within the earth during
release of accumulated strain energy.
Faulting may be considered as an immediate cause of an
earthquake. Due to constant movement of plates,
deformation is caused which results to generations of
Indian plate is moving in north-north-east direction and
colliding with Eurasian plate along the Himalayas.
It is the point on the (free) surface of the earth
vertically above the origin place (hypocentre) of an earthquake. This point is
expressed by geographical latitude and longitude.
MAGNITUDE : It is a quantity to measure the size of
an earthquake in terms of its energy and is independent
of the place of observation.
: Magnitude is measured on the basis of
ground motion recorded by an instrument and applying standard correction for the epicentral
distance from recording station. It
is related with the logarithm of amount of energy
released by an earthquake and expressed in Richter
INTENSITY: It is the rating of the effect of an
earthquake at a particular place, based on the
observations of the damaged areas, using a descriptive
scale like Modified Mercalli Scale.
CLASSIFICATION OF EARTHQUAKES
Slight : Magnitude up to
4.9 on the Richter scale
: Magnitude 5.0 to 6.9
Great : Magnitude 7.0 to 7.9
Very great : Magnitude 8.0 and more
