WHAT IS EARTHQUAKE PREPAREDNESS?

A state of readiness on individual, urban, sub-regional, and national scales that is

sufficient to keep the expected and unexpected effects of an earthquake from

causing a disaster

ANTICIPATION IS THE KEY TO PREPAREDNESS

• Strong ground shaking• Tsunami wave run up• Liquefaction• Landslides• Aftershocks• Vulnerabilities

STRONG GROUND SHAKING

GROUND SHAKING CAUSES SOCIAL AND ECONOMIC LOSSES

AS COMMUNITY PREPAREDNESS INCREASES,

SO DOES PROTECTION OF BUILDINGS AND INFRASTRUCTURE

WHAT IS PROTECTION?

A legally mandated state of planning and verified robustness, strength, and

ductility for important buildings and essential - critical infrastructure to prevent

loss of function

WHAT IS EMERGENCY RESPONSE

All of the scripted and unscripted heroic and historic responses during the “race against time” after a quake to save lives

and protect property

KEY ELEMENTS OF PREPAREDNESS

• Know your seimic activity (i.e., Seismicity )

• Know your fault zones• Know your Vulnerabilites

FAULTS

THE USA’S MOST NOTABLE PLATE BOUNDARY FAULT ZONE

• San Andreas Fault• 600 Miles long• Source of M8

Earthquakes in 1847 and 1906

THE USA’S OTHER NOTABLE PLATE BOUNDARY FAULT ZONE

• The Juan De Faca Plate• Subducting beneath

Wash and Oregon • Potential for M9.0

ONE OF THE USA’S TWO NOTABLE INTRA-PLATE FAULT ZONES

• Wasatch Fault, Utah• 250 Miles long• Potential source of

M7.0-7.5 earthquake

ONE OF THE USA’S TWO NOTABLE INTRA-PLATE FAULT ZONES

• New Madrid Seismic Zone

• Source of four (4) M* earthquakes in 1811--1812

Community preparedness and emergency management response increases as the

community’s capability to anticipate what will increases

NORTHERN CALIFORNIA SCENARIO

(developed in 2008)

BASED ON INTEGRATED KNOWLEDGE FROM MONITORING, RESEACH, AND POSTEARTHQUAKE STUDIES SINCE

APRIL 1906

NORTHERN CALIFORNIA: WHAT NEEDS TO BE ANTICIPATED?

• How likely is a damaging earthquake to occur?

• Where and when will it occur?• How big will it be?• How strong will its potential

disaster agents be?

SAN FRANCISCO BAY AREA SCENARIO

• The Bay Area is prone to large earthquakes because it straddles the boundary between two major tectonic plates — the North American and Pacific plates.

SAN FRANCISCO BAY AREA SCENARIO

• Much of the stress release happens on the San Andreas fault, but some of it is relieved by the Hayward fault and other smaller parallel faults.

A HAYWARD FAULT SCENARIO

• Because of its location in the densely populated Bay area of 7 million people, a Hayward fault quake is likely to cause worse societal impacts than a San Andreas quake and be one of the nation's largest natural disasters.

WHAT NEEDS TO BE ANTICIPATED (Continued)?

A HAYWARD FAULT SCENARIO

• Potentially affecting 5 million people, a Hayward fault quake damages homes, schools, senior centers, hospitals, businesses, the Bay bridge, and the campus of University of California, Berkeley.

WHAT NEEDS TO BE ANTICIPATED (Continued)?

• What are the social vulnerabilities?

• What is the likely damage distribution?

• What are the HAT ARE THE LIKELY CASUALTIES, SOCIO-ECONOMIC, AND ENVIRONMENTAL IMPACTS?

HAYWARD FAULT SCENARIO IN SAN FRANCISCO BAY AREA

• Damage will be extensive to buildings and infrastructure.•The region's transportation infrastructure and water delivery systems are expected to take a major hit in a M7.0 or greater earthquake.

HAYWARD FAULT SCENARIO IN SAN FRANCISCO BAY AREA

• A M7.0 earthquake on the Hayward fault will cause an estimated $210 billion dollars in damage.
