CALIFORNIA EARTHQUAKE EXERCISE OCTOBER 21, 2010 Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA
The California Earthquake Authority staged a statewide earthquake drill today (October 21 st ) to test Californians (and others throughout the world who participated) on their knowledge of earthquakes and earthquake safety.
7.8 million registered participants, as of this morning, took part in the Great California Shake Out drill designed to challenge individuals, schools, businesses and hospitals to practice state-of-the-art seismic safety measures in anticipation of the next, inevitable big quake
EARTHQUAKE SCENARIOS A DISASTER RISK REDUCTION TECHNIQUE APPLICABLE FOR ANY HIGH-RISK SEISMIC ZONE
GOAL OF A SCENARIO EARTHQUAKE PREPARING FOR THE INEVITABLE BY INTEGRATING ALL ACCUMULATED KNOWLEDGE INTO A COHERENT RISK REDUCTION MODEL
EXAMPLE: ONE OF THE WORLD’S WORST POTENTIAL EARTHQUAKE DISASTERS--- SOUTHERN CALIFORNIA (Concept Developed in 2008) Source: US Geological Survey, Southern California Earthquake Center, and local, regional, and national partners
BASED ON KNOWLEDGE ACCUMULATED THROUGH MONITORING, RESEARCH, AND POSTEARTHQUAKE STUDIES
ADVANCE PLANNING SO THAT CALIFORNIA WILL BE READY WHEN THE INEVITABLE “BIG ONES” RECUR Source: US Geological Survey
Southern California is prone to earthquakes because of its location relative to the boundary between two major tectonic plates. Much of the stress release happens on the San Andreas fault.
The goal of the ShakeOut Scenario is to identify the physical, social and economic consequences of a major earthquake in southern California, and in so doing, enable end users to identify what they can change now—before the earthquake—to avoid catastrophic impact after the inevitable “big one” recurs.
