  2. General Information • This earthquakewas of a magnitude of 9.0 on the Richter magnitude scale; • 15,845 confirmeddeaths; • 5,893 injured; • 3,380 people missing • Over 125,000 buildings damaged or destroyed; • Insuredlossesfromearthquakealoneat US$14.5 to $34.6 billion.

  3. Damage due to earthquake

  4. Population & Economy • Population Japan: 127.000.000 (aprox.); • Japan’s GDP per capita: $33,805, 24th highest in the world.

  5. Preparation • The ‘EarthquakeEarly Warning’ system, whichincludes more than 1000 seismometerssend out warnings to the Japanese population. • The JapanMeteorological Agency (JMA) alsosends out early warnings to the Japanese population • Enforced buildings, designed to withstand the abrupt seismicmovements.

  6. Vulnerability of Population • Japanisknown to lie on numeroustectonicfaultlines Population isgenerallywellprepared for earthquakes(Evacuation procedures, structures, national aidresponse, etc.) • Japan has witnessednumerous large earthquakes, however, a country canneverbefullyprepared for a disaster of this magnitude (9.0) • The population couldnever have expected a tsunami and nuclearfallout as a result of one earthquake.

  7. Probability of suchhazards • Earthquakes are verycommon in Japan.

  8. Hazardsoccured in the past • The first earthquakerecorded in Japan: 684 • Last recordedwas the earthquake on the 1st of January 2012 • 61 earthquakeswith a magnitude of 7.0 and over on the Richter scale have been recorded.

  9. Tsunami impact • The tsunami reachedCalifornia and Oregon; • Vancouver islandwas hit by the tsunami withwaves of 1m (3.3ft); • Philipinesgot hit by 0.5m waves; • Hawaii = $3 million in damages  1,5m waves • Tsunami broke icebergs of Antarcticawhichis 13,000km away area of Manhattan island.

  10. Earthquake’s duration and Magnitude • Magnitude = 9.0 on Richter magnitude scale; • Duration = 6min

  11. Impact • The earthquakelead to a tsunami  waves up to 40.5m (Japan) • Both the earthquake and tsunami lead to a meltdown in threereactors in the Fukushima NuclearPowerplant.

  12. Responses to disaster • Aidorganization in Japan and worldwiderespondedwith the JapaneseRed Cross reporting $1 billion in donations. • Complete evacuation of surroundingcommunities of the Fukushima Nuclear Power Plant  Over 200,000 people wereevacuated.
