July 10, 2010 (San Diego’s East County) – Fault lines in and near East County have become more active since the Easter earthquake in Mexico. Both the San Jacinto and Elsinore faults have potential for a quake measuring 7.0 or higher, according to the U.S. Geological Survey. Fortunately, planning and identifying hazards ahead of time can reduce risk of serious harm before an earthquake hits.
For example, repairing deep plaster cracks in ceilings and foundations, anchoring overhead lights to the ceiling, and upgrading to meet local seismic building standards help reduce the impact of a quake. Creating an emergency supply kit and a family evacuation plan are also important. Below are earthquake safety tips providing by the Federal Emergency Management Agency (FEMA) that you can take now—before a major quake hits our region.
