Understanding
the EARTH QUAKE.
The important factors are:
Earth
structure
Arrangements
of layers
Rupture
and re formations
Tectonic
plates
History
Quake
zone and data
Understanding
the data
Analysis
Knowing
local factors
Extrapolation
and prediction.

Earth structure
Only outer crust is solidified to form the thin land layer.
The radius of the earth is about 6000 km.Out of this, only 50 km is solid. So, in
a radius of 6000 km, 50 km is < 1%.
It is something like a balloon filled with water! But
it is not bursting because, no one is hitting it!
Arrangements of layers
Outer layer is solid, next is liquid having molten
rocks. Innermost layer is believed to be semi solid due to high pressure.
Rupture and re formations
Earth is still a dynamic system inside, with rupturing
and re formation due to flowing of molten rock. This is also one of the reasons
for Earthquakes.
Tectonic plates
There are divisions in the earth's crust. It is not a
single piece. So, these are called as Tectonic plates.
These plates are moving against each other in some order.
Whole of Himalayan Mountains are due to these movement. This is the most
important reason for earthquake.
History
One
of the important things is to know the history of quakes of a particular region.
This will largely help in prediction.
Quake zone and data:
There are zones in the world near
the edges of tectonic plates which are prone to large and frequent earth
quakes. Large data over a range of 10 years is to be collected for each zones
for study.
Understanding the data:
This is the trickiest part of
all. Many times some intuitive talent is required to get a relationship and
trend to match the huge data.
Analysis
All the possible curve fittings of graphs
and possible relations of the data are to be analyzed in detail to take a step
in prediction.
Knowing local factors
Local factors like mountains,
buildings, rivers, lakes seas, volcanoes and underground faults will all affect the quake. Hence a good knowledge is required about these things.
Extrapolation and prediction
The graphs are to be
extrapolated to get the prediction. But coming to sudden conclusion in any
direction is bad because IT IS A QUAKE AND NOT A JOKE!
