More so, as I am an amateur. But still, I would like to stay on and learn a bit. May be you all may help me understand somethings that are intriguing me regarding earthquakes. 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. Himanshu >> Hello Himanshu: If you have access to a technical library, you might get a copy of a recent textbook on ground water hydrology or hydrogeology. These books usually have a section that discusses earthquakes and their effects on ground water. For example, the book that I have handy is: Physical and Chemical Hydrogeology, by Patrick A. Domenico and Franklin W. Schwartz (John Wiley and Sons publishers). The authors discuss earthquakes and ground water on pages 313-315 and cite a number of reports on the subject. Hope this is helpful. Bob Laney Herndon, Virginia __________________________________________________________ Public Seismic Network Mailing List (PSN-L)
