First, I am from India and live near Gujarat state,
which was rocked on January 26 by a devastating quake.
What I want to know is about the relation between
anomolous behaviour of ground water with seismic
activity. I read in a book that there is a research
going to predict earthquakes by studying the behaviour
of ground water table (shifting places, etc) before
the tremors. I understand that there is a strong link,
and changes in ground water level can be traced 3-4
months before the main shock. Can somebody fill me up
on this.
Sorry, if I sound like an idiot. In that case please
correct me.

There is a paper by Eddie Quilty at the USGS in Menlo Park.

Title:

Water Level and Strain Changes Preceding and Following the August 4, 1985
Kettleman Hills, California Earthquake.

Authors Evelyn Roeloffs and Eddie Quilty

A Report from Pure Applied geophys. 149 (1997) 21-60 033-4553/97/010021-36

It has some very interesting information on well levels.

I think there were also some articles years ago in Scientific American
Magazine that discussed well levels and earthquakes.
