Definition

  • The giant earthquake (Magnitude 9.0) off Tohoku, Japan, was the largest earthquake in Japan’s history.

  • It caused nearly 20,000 casualties, mostly from devastating tsunamis.

  • The earthquake and tsunami also caused serious damage to the Fukushima nuclear power station, causing meltdown of the reactor, hydrogen explosion, and release of radioactive materials.

  • Similar tsunami hazards occurred in the past, but the experience was not utilized to reduce the disaster.

  • The lessons learned include the reexamination for preparedness for such infrequent hazards.

Introduction

A giant earthquake (official name: off the Pacific coast of Tohoku earthquake, abbreviated as the Tohoku earthquake) occurred near northern Honshu, Japan, on March 11, 2011. This earthquake, with magnitude M 9.0, was the largest in Japan’s history, and produced a devastating tsunami disaster, as well as serious damage to the nearby Fukushima Dai-ichi nuclear power station.
