Noted Speaker to Discuss Potential for Predicting Earthquakes in California

Apr 12, 2011

When and where will the next "big one" occur?

Lecture by Dr. Kaj Johnson, NSF EarthScope Distinguished Speaker

Tuesday, April 19, 2011

5:00 p.m. in Olson Hall

Dr. Kaj JohnsonUniversity of the Pacific is honored to host a lecture by Dr. Kaj M. Johnson on Tuesday, April 19 at 5:00 p.m. in Olson Hall (Physics), Room 120. Dr. Johnson, a professor of Geological Sciences at Indiana University, is a National Science Foundation (NSF) EarthScope Distinguished Speaker for 2010-2011. As such, he is traveling the nation to give lectures at other universities and spread the word about the EarthScope initiative.

EarthScope is a program of the NSF that deploys thousands of seismic, GPS, and other geophysical instruments to study the structure and evolution of the North American continent and the processes the cause earthquakes and volcanic eruptions.

The program, which involves collaboration between scientists, educators, policy makers, and the public, includes an EarthScope Speaker Series, where accomplished scientists are selected to present results of EarthScope research to faculty and students in departmental seminars at colleges and universities.

Dr. Johnson is lecturing about the potential for earthquakes on and off major faults in California. He will discuss data being collected through the EarthScope program and examine the question, "Where is stress accumulating in the crust, and will it be released in future large earthquakes?"

Come to the talk on April 19 to find out what he has to say.

Judson Mead Assistant Professor,

Bloomington, Indiana

Kaj Johnson has B.S. and M.S. degrees in Mathematics and Structural Geology from Purdue University, and a PhD in Geophysics from Stanford University. He works primarily with geodetic data and numerical and analytical models to investigate how deformation within plate boundary zones is accommodated by faulting and folding in the upper crust, and by viscous flow in the lower crust and upper mantle. His current research topics include: mountain building in Taiwan; afterslip and fault friction; relationship of interseismic and postseismic deformation to lithosphere rheology; and probabilistic inverse theory.
