4. NEW RESEARCHERS FROM THE
USGS HAVE LEARNED NEW DATA
THAT SUGGESTS A CALIFORNIA
“BIG ONE”
COULD HAPPEN SOON.

7. RESEARCHERS ANALYSED THE LATEST DATA
FROM THE STATE’S COMPLEX SYSTEM OF
ACTIVE GEOLOGICAL FAULTS, AS WELL AS
NEW METHODS FOR TRANSLATING THESE
DATA INTO EARTHQUAKE LIKELIHOODS.
THE ESTIMATE FOR THE LIKELIHOOD THAT
CALIFORNIA WILL EXPERIENCE A
MAGNITUDE 8 OR LARGER EARTHQUAKE IN
THE NEXT 30 YEARS HAS INCREASED FROM
ABOUT 4.7% TO ABOUT 7.0%

8. ‘WE ARE FORTUNATE THAT SEISMIC ACTIVITY IN
CALIFORNIA HAS BEEN RELATIVELY LOW OVER THE
PAST CENTURY,’ SAID TOM JORDAN, DIRECTOR OF
THE SOUTHERN CALIFORNIA EARTHQUAKE CENTER
AND A CO-AUTHOR OF THE STUDY.
‘BUT WE KNOW THAT TECTONIC FORCES ARE
CONTINUALLY TIGHTENING THE SPRINGS OF THE
SAN ANDREAS FAULT SYSTEM, MAKING BIG
QUAKES INEVITABLE.
‘THE UCERF3 MODEL PROVIDES OUR LEADERS AND
THE PUBLIC WITH IMPROVED INFORMATION ABOUT
WHAT TO EXPECT, SO THAT WE CAN BETTER
PREPARE.’

11. THE STUDY CONFIRMS MANY PREVIOUS FINDINGS,
SHEDS NEW LIGHT ON HOW THE FUTURE
EARTHQUAKES WILL LIKELY BE DISTRIBUTED ACROSS THE
STATE AND ESTIMATES HOW BIG THOSE EARTHQUAKES
MIGHT BE.
COMPARED TO THE PREVIOUS ASSESSMENT ISSUED IN
2008, UCERF2, THE ESTIMATED RATE OF EARTHQUAKES
AROUND MAGNITUDE 6.7, THE SIZE OF THE
DESTRUCTIVE 1994 NORTHRIDGE EARTHQUAKE, HAS
GONE DOWN BY ABOUT 30 PERCENT.

17. A softer soil behaves a little like quicksand during an
earthquake if there are traces of water in it. The loss in
the strength of the soil due to strong squeeze leads to
the process called liquefaction resulting in the sinking o
the building which often topples. The earthquake is
particularly devastating when
the frequency of the seismic waves matches the
natural frequency of the buildings. This is called
resonance phenomenon. When such a phenomenon
occurs, multiple waves at resonance frequency pass
through the buildings leading to destructive
consequences.

34. NOTE:

35. THIS IS AN IMPORTANT MESSAGE FROM THE U.S.
DEPARTMENT OF HEALTH AND HUMAN SERVICES. APPLY
FIRST AID TO TREAT CUTS AND SCRAPES AND PREVENT
INFECTION. TO CARE FOR A BLEEDING CUT, PUT PRESSURE
ON IT UNTIL THE BLEEDING HAS STOPPED. CLEAN THE
WOUND BY GENTLY POURING CLEAN TAP OR BOTTLED
WATER OVER IT. NEXT, APPLY A CLEAN, DRY BANDAGE. IF
YOU THINK THE CUT IS INFECTED, GET MEDICAL HELP AS
SOON AS POSSIBLE.
TO LEARN MORE, CALL CDC AT 800-CDC-INFO.

36. THE FOLLOWING IS AN IMPORTANT PUBLIC HEALTH
ANNOUNCEMENT.
DEAD BODIES RARELY CAUSE OR SPREAD DISEASE. IF YOU ARE
HANDLING REMAINS, PROTECT YOUR HANDS AND FEET FROM
SHARP OBJECTS TO PREVENT CUTS. AVOID GETTING BLOOD OR
BODY FLUIDS ON YOUR FACE. AVOID TOUCHING YOUR FACE
AND CLEAN YOUR HANDS WITH SOAP AND CLEAN WATER AS
SOON AS POSSIBLE. IF YOU ARE WOUNDED WHILE CLEANING
UP, IMMEDIATELY CLEAN YOUR WOUNDS WITH SOAP AND
CLEAN WATER, AND ASK A DOCTOR FOR A TETANUS SHOT.
THESE TIPS CAN SAVE LIVES…BE SAFE.

44. "EVERYONE WILL PANIC DURING THE BIG
ONE!"

49. CHECK FOR INJURIES
• CHECK YOUR FIRST AID KIT OR THE FRONT PAGES OF YOUR TELEPHONE BOOK
FOR DETAILED INSTRUCTIONS ON FIRST AID MEASURES.
• IF A PERSON IS BLEEDING, PUT DIRECT PRESSURE ON THE WOUND. USE CLEAN
GAUZE OR CLOTH, IF AVAILABLE.
• IF A PERSON IS NOT BREATHING, ADMINISTER RESCUE BREATHING.
• IF A PERSON HAS NO PULSE, BEGIN CPR (CARDIOPULMONARY
RESUSCITATION).
• DO NOT MOVE SERIOUSLY INJURED PERSONS UNLESS THEY ARE IN IMMEDIATE
DANGER OF FURTHER INJURY.
• COVER INJURED PERSONS WITH BLANKETS OR ADDITIONAL CLOTHING TO KEEP
THEM WARM.
• GET MEDICAL HELP FOR SERIOUS INJURIES.
• CAREFULLY CHECK CHILDREN OR OTHERS NEEDING SPECIAL ASSISTANCE.

50. AS PREVIEWED BY THE SIGNIFICANT DAMAGES
RESULTING FROM THE 1989 LOMA PRIETA EARTHQUAKE
IN NORTHERN CALIFORNIA (MAGNITUDE 7.1) AND THE
1994 NORTHRIDGE EARTHQUAKE IN SOUTHERN
CALIFORNIA (MAGNITUDE 6.8), THE IMPACT OF THE
PREDICTED HIGHER MAGNITUDE EARTHQUAKES IN
CALIFORNIA AND THE CENTRAL UNITED STATES COULD
POTENTIALLY KILL AND INJURE THOUSANDS OF PEOPLE,
RESULT IN BILLIONS OF DOLLARS IN PROPERTY LOSS,
AND CAUSE SEVERE DISRUPTIONS TO THE UNITED STATES
ECONOMY.
