• Every state in the U.S. has had an earthquake

5. Earthquakes in Alaska

6. Alaska
• March 9 1957 Andreanof Island has a M 8.6
• Bridges are damaged docks destroyed and it
even caused Mount Vsevidof to Erupt which was
dormant for 200 yrs.
• Caused a Tsunamis which continued to
Hawaii, California, Chile, El Salvador, and Japan
• More than 300 aftershocks where reported

7. Alaska
• They also had earthquakes on March

8. Alaska
• July 10, 1958 Lituya Bay, Alaska has a M 7.7
earthquake
• Not much damage to man made works
minimal since there was not much in alaska
• Landslides reported in the mountains

Earthquake of
1964

15. The Initial Event
•Occurred
Friday, march
27th 1964 at
5:36 P.M.
•Lasted three
minutes

16. Aftershocks
• Thousands of large
aftershocks that were
felt up to three weeks
after the initial event
• Caused many
landslides and
subsidence
• Up to magnitude 7
• Some occurred up to a
year later

17. Epicenter
• Epicenter was located 12.4 miles north of Prince
William Sound, 78 miles east of Anchorage

18. The earthquake registered at
9.2Mw

19. The Damage
• Caused $311 million (2.26 billion in current U.S. dollars) in
Alaska and other places
• Cleanup took 15+ years to complete

20. Tsunamis and Surge Waves
• The quake and its aftershocks created
tsunamis that caused damage in
California, Hawaii and Oregon
• The tsunamis were up to 30ft tall
• Some water levels were up to 80ft above sea
level
• The towns of Whittier, Valdez, and Kodiak
were almost completely destroyed

21. Surge Wave Damage
Kodiak, AK

22. Surge Wave Damage
Seward, AK

23. Deaths Caused
• 128 people killed
– 113 from the tsunamis
– 15 from the earthquake
• The death toll would
have been much
greater had the quake
occurred present day

24. Subsidence
• The earthquake created grabens up to 8ft
deep

25. Tectonic Uplift

26. Both of these areas were more than 30ft underwater
before the event.
The quake caused the land in some places to rise so
rapidly that trees were torn
in half.

27. Fissures
The earthquake left large fissures in roads and
bedrock, some were up to 6ft wide

28. Earthquakes
Seismic waves &
Destruction of property

29. • Different motions of Earthquakes.

30. • Are the fastest waves
and are the first waves recorded by
seismographs.
Some call P-waves push-pull wave because of
the way they contract and expand as they are
traveling

31. Visual example of a p-wave

32. S-Waves can’t travel through liquids or
gases. They require rigid material like
ground, rock, roads or buildings

33. Visual example of a S-wave

35. Human interaction
• Base isolation bearings

36. Elastic Cables
Steel frame Shoes
Steel fuses (in blue)
