JMA’s Tsunami Warning for the 2011 Great Tohoku Earthquake and Tsunami Warning Improvement Plan
Seismological and Volcanological Department, Japan Meteorological Agency, Otemachi 1-3-4 Chiyoda-ku, Tokyo 100-8122, Japan
The Japan Meteorological Agency (JMA) issued a timely tsunami warning three minutes after the 2011 off the Pacific coast of Tohoku Earthquake (the Great Tohoku Earthquake) occurred at 14:49 (JST) on March 11, 2011. However, predicted tsunami heights at the early stage were greatly underestimated. Based on lessons learned from this earthquake, the JMA plans to improve its tsunami warning.
