John Armbruster is a seismologist with Lamont-Doherty Earth Observatory of Columbia University. He is from the New York City area, went to Rensselaer Polytechnic Institute in Physics and has been with Columbia University since 1969. He has always been interested in earthquakes in the eastern U.S. but also worked on projects in Pakistan, India, Bangladesh, China, Turkey and Italy. He lived in Pakistan almost 4 years and was in Abbottabad many times. From 1987 to 2003 I studied earthquakes in Ashtabula Ohio that I concluded were caused by a waste injection well.
