CALIFORNIA EARTHQUAKE EXERCISE

OCTOBER 21, 2010

Walter Hays, Global Alliance for Disaster Reduction, University of North Carolina, USA


Slide2 l.jpg

The California Earthquake Authority staged a statewide earthquake drill today (October 21st) to test Californians (and others throughout the world who participated) on their knowledge of earthquakes and earthquake safety.


Slide3 l.jpg

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

Southern california shakeout scenario l.jpg

SOUTHERN CALIFORNIA “SHAKEOUT: SCENARIO

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.


Shakeout scenario l.jpg

SHAKEOUT SCENARIO

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 identifywhat they can change now—before the earthquake—to avoid catastrophic impact afterthe inevitable “big one” recurs.

The mw 7 8 shakeout quake l.jpg

THE Mw 7.8 SHAKEOUT QUAKE

The magnitude 7.8 ShakeOut earthquake causes about 1800 deaths and $213 billion ofeconomic losses.


The m 7 8 shakeout quake l.jpg

THE M 7.8 SHAKEOUT QUAKE

These numbers are as low as they are because of aggressive retrofitting programs that have increased the seismic resistance of buildings, highways and lifelines, and added economic resiliency.


The mw 7 8 shakeout quake26 l.jpg

THE Mw 7.8 SHAKEOUT QUAKE

The estimates of about 1800 deaths and $213 billion of economic losses are as large as they are because much more retrofitting could still be done.
