CEPEC Issues "Earthquake Advisory" For Bay Area Counties in Response to
Magnitude 5.6 Earthquake

In response to Tuesday evening's magnitude-5.6 earthquake near the
junction of the Calaveras and Hayward faults, the following statement
was issued by the California Earthquake Prediction Evaluation Council,a
panel of scientists chaired by the State Geologist that advises the
Director of the Governor's Office of Emergency Services (OES) on the
scientific validity of earthquake forecasts and seismic activity in
areas where damaging earthquakes have occurred in the past.

"A magnitude 5.6 earthquake occurred at 8:05 Tuesday evening (30
October 2007). The earthquake occurred near the junction of the
Calaveras and Hayward faults in the southern San Francisco Bay Area.
Both of these faults are known active faults capable of producing
large, damaging earthquakes.

"CEPEC believes that this evening's earthquake has significantly
increased the probability above the normal level for a damaging
earthquake along the Calaveras and/or Hayward faults within the next
several days. However, the overall likelihood of such an event is still
low. Scientists will be continuing to monitor the situation and advise
OES of any changes.

In response to the CEPEC evaluation of this earthquake, OES recommends
that residents of the San Francisco Bay region review their family
emergency plans, check their emergency supplies, identify the "safe"
and "potential danger" spots in each room, remove breakables from
locations from which they can fall and cause injury, and stay tuned to
the radio or television for further information. OES also recommends
that government agencies and businesses review their plans.

The "advisory" applies to the following counties: Alameda, Contra
Costa, Marin, Monterey, San Benito, San Francisco, San Mateo, Santa
Clara, Santa Cruz, Solano and Sonoma.
