On Thursday, Oct. 18, at 10:18 a.m., Claremont Graduate University will participate in the California Shakeout drill. Students, staff and faculty will receive a phone call, email, and/or text notification from our Connect Ed system to start the drill and another notification to end the drill.
We are asking students, faculty, and staff to stop their activities at that time and take a cover position. When you receive the notification that the “earthquake” is underway, stop your activities, and move into a safe position as if you were experiencing a real earthquake. Wait for the all-clear notification before resuming your normal activities. We will not be doing an evacuation drill.
Please make sure your contact information on http://my.cgu.edu is up-to-date.
California is an active seismic area. As in most places in California, Claremont Graduate University is near identified earthquake faults: the Cucamonga Fault at the base of the foothills north of campus, and the infamous San Andreas Fault about 30 miles to the east. There are also numerous smaller faults all along the foothills north of Claremont. There are also unknown fault zones; many only become known to seismologists after an earthquake. The 1994 Northridge quake was on a previously unknown fault. When it ruptured it measured 6.7 on the Richter Scale and caused billions of dollars in damage and many fatalities.
Large earthquakes can sometimes be preceded by a foreshock, a smaller quake within a few minutes to a few hours of the larger quake. That is why it is important to follow the safety precautions when you feel an earthquake and exit any unsafe environments as quickly as seems prudent afterwards. Aftershocks also occur after every earthquake. The larger the quake, the larger the aftershocks. A building that may survive the initial earthquake may come down with aftershocks.
It is important for all Californians to educate themselves on earthquake hazards. There are several good websites with important information to protect your family and your property. Here are a few:
CA Earthquake Authority www.earthquakeauthority.com
So. Calif. Earthquake Center www.SCEC.org
Federal Emergency Management Agency www.FEMA.gov
Earthquake Country Alliance www.earthquakecountry.info
