What is Earthquake?
When the earth tremble
due to some reason. It is called Earthquake.
��Cause of Earthquake��1-Collision of the tectonic� plates under the earth crust��2-Volcanic eruption.��3-Explosion of Atom bombs
What do when earthquake come:-
1- If possible leave the house and go to an
open ground.
2- If you cannot go out of the house, lie
down under a strong thing like a table and
hold on tightly,so that it does not slip
away.Wait until the shaking stops.
3- Try to stand in between the space of the
door or window.
Reports on Earthquake
The Bhuj earthquake (Mw 7.7) ofthe State of Gujarat, is the
most January 26, 2001, that occurred in disastrous
earthquake in India’s history. While the actual figures of
death and injury remain uncertain, going by the official
figures, at least 20,000 people were dead and more than
200,000 were injured. Nearly 400,000 houses were
destroyed and twice as much damaged. Although damages
of such proportion were astonishing, the occurrence of the
event itself was not surprising, considering the geologic and
seismic history of the region. Seismologists, Drs. Kusala
Rajendran and C.P. Rajendran from CESS, visited Bhuj
during February 12 to March 5, 2001, for post seismic field
observations and to assess the damage pattern and study
the response of structures, field effects and aftershock
activity.
The Bhuj earthquake has also destroyed
several historical monuments in the region,
dating from 9th century A.D. The Sun Temple
at Kotai (11th century A.D.) and the Punvareshwar
Temple at Manjal (9th century A.D.) are among the
oldest temples that were destroyed. While the
Lakhpatji’s Chhatardi (A.D. 1752-61) collapsed
completely, Aina Mahal Palace(~ 200 years old)
is still standing, with extensive damage.
These structures seem to have survived the
1819 and 1956 earthquakes, but the ground
shaking was apparently too severe during the recent
earthquake.
Although the damage was not severe,
it is conceivable that the Bhuj earthquake
was the largest to have occurred in the close
proximity of these structures since 9th century A.D
Uttarkashi earthquake
The 1991 Uttarkashi earthquake (M 6.5) which occurred in the Tehri region in Gharwal Himalaya shook the north-central India
This earthquake, a moderate one, attracted a lot of attention due to its proximity to the high Tehri dam
This is among the recent earthquakes that have been instrumentally recorded and studied
This event killed many people and damaged completely or partially about 48,000 houses
Geologists believe that this earthquake occurred because of a slippage
along the Main Central Thrust
(MCT), a major tectonic boundary, which also divides lesser Himalayan
terrain in the south from the
snow clad mountains in the north
Latur earthquake :-
The Latur (Killari), Maharashtra, earthquake of September
30, 1993 is the most devastating SCR earthquake in the
world.Its epicentre was located in a region considered to be
aseismicThis earthquake occurred in the typical rural setting
of India. The severity of the destruction was compounded by
the nature of village settlements. While most of the
engineered structures survived the earthquake, the non-
engineered ones were totally damaged.Over 10,000 lives
were lost in this earthquake and several villages were
destroyed. With a magnitude 6.3 and focal depth less than
10 km, this earthquake is similar to other moderate events in
the Australian and Canadian shields.
