Cliff Frohlich is an earthquake seismologist and Associate Director at the University of Texas Institute for Geophysics (UTIG), where he has been employed since 1978. He is the word’s leading authority on Texas seismicity, a coauthor of the book Texas Earthquakes, and a co-author on the recent paper in Leading Edge describing the 2008-2009 Dallas-Fort Worth earthquakes. However, being the world’s leading authority on Texas earthquakes is not a full-time job, and he is better known internationally for his research on deep-focus earthquakes, moonquakes, and tsunamis. In 2008 he was chosen as a Distinguished Lecturer for the Incorporated Research Institutions for Seismology (IRIS) and the Seismological Society of America (SSA).
