Tidal forces parellel to a segment of the San Andreas Fault in central California may be causing tremors that could help predict earthquakes


Summary: According to a study by researchers at Washington (Reuters), tidal forces on the San Andreas fault in central California causes non-volcanic tremors well below the level where earthquakes occur. The research says studying tremors could help seismologists better understand and, perhaps, predict earthquake activity.

Classroom Strategy: Ask students to brainstorm ideas how the earthquakes can be predicted. Then let them research in small groups to find the solution to the problem. Students may use library books, encyclopedia or Internet. Have them present their findings. Students may/may not be able to find the information about the latest research about the prediction of earthquakes. If not news can be introduced and discussed in the class.
