One of the greatest things about the Internet is that as
an individual you can have access to some of the latest
research information. Years ago this type of information
would only have been available to top scientists in their
field.
NASA scientists have proposed a new theory on the
cause of major Earthquakes. If the magnetosphere is
hit by Solar flares and CME (Coronal Mass Ejections)
from the Sun, of a great enough intensity, it can cause
what they call a space quake. This is equivalent to a
earth quake of 5 or 6 on the Richter scale.
The theory goes that the solar flare, or CME of
sufficient magnitude strikes the Earth's Magnetosphere,
this places pressure on the Earth's tectonic plates and
can cause Earthquakes. The Magnetosphere is a
naturally formed magnetic field around the Earth
created by the Earth's iron core, it protects the Earth
against Solar flares and CME's.
Here is an analogy. Imagine that the Earth is like a a
boiled egg that you have dropped. When you pick it up
the egg shell is broken into many pieces. If you gently
squeeze that egg, the shell, representing the Earth's
tectonic plates that make up the Earth's crust, will
move against each other. So when the solar flare or
CME hits the Earth's magnetosphere, it squeezes it,
which in turn puts pressure on the Earth's crust.
Both the recent New Zealand and Japanese Earth
Quakes occurred during an X chase solar flare which
also caused a geomagnetic storm in the earth's
magnetosphere. During the Japanese quake it was
reported that the Earth's magnetosphere was also hit
by a CME at the same time the X class flare hit.
Here is a site where you can monitor solar flare activity
in real time.

This site will allow you to monitor Earthquake activity
around the world in real time.

If this theory is correct, this info is great because it will
give an idea if something is going to happen, it just
won't indicate where or when.
New discoveries suggest where and when may be able
to be predicted. One study has found that satellites
have been recording variations in ULF or VLF radio
signals (Ultra/Very Low Frequency) signals from where
Earthquakes were about to occur. Also slight increases
in earth crust levels can be an indicator. So these two
satellite projects are exploring these indicators to see if
they can give an early warning of where an Earthquake
may occur.

Another study has found that major earthquakes
usually occur where there are large quartz deposits in
the rock formations on fault lines. There appears to be
more water in quart deposits which allows more
slippage in the crust at those points. This would also
explain why electrical disturbances can appear before
an earth quake. Lights in the sky or animals who use
magnetic field information to navigate becoming
confused or die. Think of the old quartz radios. Quartz
and mineral crystals in bed rocks under a lot of
pressure would generate an electrical signal giving an
indication of an impending quake.
So there appears to be significant advancements in
Earthquake predicting technologies. Putting it all
together as an accurate predictor may be some years
away.
