19. 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

20. ANTICIPATION IS THE KEY TO
PREPAREDNESS
• Strong ground shaking
• Tsunami wave run up
• Liquefaction
• Landslides
• Aftershocks
• Vulnerabilities

21. STRONG GROUND SHAKING

22. GROUND SHAKING CAUSES SOCIAL AND
ECONOMIC LOSSES

23. AS COMMUNITY PREPAREDNESS
INCREASES,
SO DOES PROTECTION OF BUILDINGS
AND INFRASTRUCTURE

24. 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

25. 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

26. KEY ELEMENTS OF PREPAREDNESS
• Know your seimic activity (i.e.,
Seismicity )
• Know your fault zones
• Know your Vulnerabilites

27. FAULTS

28. THE USA’S MOST NOTABLE PLATE BOUNDARY
FAULT ZONE
• San Andreas Fault
• 600 Miles long
• Source of M8
Earthquakes in 1847
and 1906

29. THE USA’S OTHER NOTABLE PLATE BOUNDARY
FAULT ZONE
• The Juan De Faca Plate
• Subducting beneath
Wash and Oregon
• Potential for M9.0

30. 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

31. ONE OF THE USA’S TWO NOTABLE
INTRA-PLATE FAULT ZONES
• New Madrid Seismic
Zone
• Source of four (4)
M* earthquakes in
1811--1812

32. Community preparedness and emergency
management response increases as the
community’s capability to anticipate what
will increases

37. NORTHERN CALIFORNIA
SCENARIO
(developed in 2008)
BASED ON INTEGRATED KNOWLEDGE
FROM MONITORING, RESEACH, AND
POSTEARTHQUAKE STUDIES SINCE
APRIL 1906

38. 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?

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

44. • 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.

45. • 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.

47. DAMAGE
PHYSICAL EFFECTS CAUSE SOCIETAL
IMPACTS AND RISK

48. WHAT NEEDS TO BE ANTICIPATED
(Continued)?
• What kinds of buildings are at
risk?
• What kinds of basic, essential,
and critical infrastructure are
at risk?
• What are the physical
vulnerabilities?

49. • 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.

50. 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?

51. • 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.

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