UCLA Seismology: Karen Felzer

Karen Felzer has moved to the U.S. Geological Survey and this page is no longer being updated. For the current version of this page please click here!

// Karen Felzer is a postdoc at UCLA with Professor Emily Brodsky. She did her graduate work in the seismology group at Harvard University with Professor Göran Ekström in the Department of Earth and Planetary Sciences and Professor Jim Rice in the Division of Engineering and Applied Sciences. She did her undergraduate work in geophysics at Stanford University with Greg Beroza. Her research involves using statistical techniques to study the physics of earthquake interaction. Her current work is on testing whether earthquakes are capable of slowing down the occurrence of other earthquakes (commonly known as the phenomena of "stress shadowing") and on investigating distant triggering. Karen has also done work on foreshocks, secondary aftershocks, fault discontinuities, and tsunamagenic earthquakes (please see papers below).
