Dr. Ann Bykerk-Kauffman 
Faculty, CSU, Chico Department of Geological and Environmental Sciences 

In clear language and with a helpful PowerPoint presentation, Dr. Bykerk-Kauffman explains the geology behind the massive earthquake that hit Japan on March 11, 2011. She notes that this 9.0 quake lasted for minutes instead of seconds, and illustrates why it was so devastating. Faults, plates, deep-sea trenches, and seismic waves are all part of the discussion.
