1. Natural Service functions of earthquakes
E.g., zinc, gold,
silver, and other
mineral resources
are deposited along
faults by
groundwater

3. tectonic processes are responsible for most
of the world’s mountain chains

4. unfortunately, none of these methods can be consistently successful
several PRECURSORS have been used to attempt
earthquake prediction include:

In China in 1975, a M 7.0 quake
was predicted based a series of
M 4.0 foreshocks; thousands of
lives were saved
The Chinese gov. did not release detail about the quake and its damage until 5 years afterwards. It struck in an area not along a plate boundary.

6. The idea of a seismic gap relates to the concept of the earthquake cycle—

7. Historical and geologic evidence can be used
to reconstruct earthquake history in an area
Year of Time
quake interval (yr)
1550
avg. interval = 122 yr
probability = 1 in 122
or 0.8 %

12. earthquake warning systems—designed to detect
an earthquake as it occurs and relay warning to
nearby cities via satellite
probable warning time: to 1.0 min

13. Earthquakes—anticipatory mitigation strategies
schools
hospitals
power plants
communications systems
police and fire departments

14. after large earthquakes, emergency officials
often experience delays in trying to reach
quake victims because of damage to:

15. These building designs are often required by
state of local governments.

16. In developing countries, a major killer during
earthquakes are building constructed of

17. earthquake drills in schools
earthquake disaster exercises
educational literature, workshops, training

18. a home inspection is required before issuing an
earthquake policy
normally, you cannot purchase a new earthquake policy
immediately after a major earthquake due to the
threat of aftershocks

19. Personal Emergency Preparedness for Earthquakes:
What can you do before an earthquake to prepare
for it?

20. What should you do if you are in an earthquake?
stay inside
drop, cover, and hold on
get under a heavy table or
desk, stay away from windows
don’t use candles until gas lines have been checked
stay away from buildings and power lines
stop the vehicle away from buildings and power lines
stay in the vehicle
