Public lecture on new understanding of detecting earthquakes via electrical signals generated in deformed rock. Signals may be picked up by satellite and warnings generated in response.

From changes in the ionosphere and abnormal weather conditions to strange animal behavior, pre-earthquake signals have a long and controversial history. Freund will speak about the exciting new developments in the field that hold the key to understanding these varied phenomena.
