Dr. Elizabeth Cochran is a geophysicist with the US Geological Survey in Pasadena, California. As an observational seismologist, her research ranges from studying the detailed behavior of fault slip to developing new techniques to densely observe earthquakes. Dr. Cochran conducts detailed studies of aftershock behavior, fault zone properties, and deep seismic slip (tremor). After a large earthquake, large numbers of seismic stations are installed in near the mainshock to record the hundreds to thousands of aftershocks that will occur over the subsequent months.
