Earthquake case study: Chile- April 2014
Causes and background
Large earthquake of magnitude 8.3 occurred of the coast of Chile followed
by several violent aftershocks, the highest of which being 7.6.
Caused by the destructive plate boundary between the Pacific plate and the
South American plate. Chile is located on this boundary so is vulnerable to
Despite the high magnitude the damage has been less than what would be
expected of an earthquake like this due to Chile's preparedness for
earthquakes which is a result of the high amounts of earthquakes they
receive such as: strict building regulations, good emergency procedure, and
earthquake proof buildings all reduced impact significantly.
Chile is an LEDC but is becoming earthquake resilient due to the frequency
of earthquakes
Power cuts, landslides, fires, waves of up to 6ft
2500 homes suffer significant damage
6 died due to heart attacks or collapsing buildings
300 women inmates escaped from a prison
Communication issues as roads become blocked
State of emergency declared
Several powerful aftershocks continuing to cause further damage
Tsunami warning- those living on the coast were evacuated to higher ground
although this was later deactivated as waves were not high enough to pose a
significant risk. However a tsunami warning for Hawaii remains in place as
waves could be dangerous to people on the beaches.
Special forces have been deployed to guard against looting
Emergency services deployed to worst hit areas to help with any
trapped/injured people.
Responses have been reported to be efficient and well organised
