Population & Economy
• Population Japan: 127.000.000 (aprox.);
• Japan’s GDP per capita: $33,805, 24th highest in the world.
Preparation
• The ‘Earthquake Early Warning’ system, which includes more than 1000 seismometers send out warnings to the Japanese population.
• The Japan Meteorological Agency (JMA) also sends out early warnings to the Japanese population
• Enforced buildings, designed to withstand the abrupt seismic movements.
Vulnerability of Population
• Japan is known to lie on numerous tectonic fault lines Population is generally well prepared for earthquakes (Evacuation procedures, structures, national aid response, etc.)
• Japan has witnessed numerous large earthquakes, however, a country can never be fully prepared for a disaster of this magnitude (9.0)
• The population could never have expected a tsunami and nuclear fallout as a result of one earthquake.
Probability of such hazards
• Earthquakes are very common in Japan.
Hazards occured in the past
• The first earthquake recorded in Japan: 684• Last recorded was the earthquake on the 1st
of January 2012• 61 earthquakes with a magnitude of 7.0 and
over on the Richter scale have been recorded.
Tsunami impact
• The tsunami reached California and Oregon;• Vancouver island was hit by the tsunami with
waves of 1m (3.3ft);• Philipines got hit by 0.5m waves;• Hawaii = $3 million in damages 1,5m waves• Tsunami broke icebergs of Antarctica which is
13,000km away area of Manhattan island.
Earthquake’s duration and Magnitude
• Magnitude = 9.0 on Richter magnitude scale;
• Duration = 6min
Impact
• The earthquake lead to a tsunami waves up to 40.5m (Japan)
• Both the earthquake and tsunami lead to a meltdown in three reactors in the Fukushima Nuclear Powerplant.
Responses to disaster
• Aid organization in Japan and worldwide responded with the Japanese Red Cross reporting $1 billion in donations.
• Complete evacuation of surrounding communities of the Fukushima Nuclear Power Plant Over 200,000 people were evacuated.
