The Great East Japan Earthquake - the sequence of events (in chronological order)

March 11, 2011 at 14:46 JST. The Tohoku Regional Bureau entered a “state of emergency” at the same time as the occurrence of earthquake. We believe that this was the same case for other institutions. The sequence of events has been organized here in chronological order. The record starts from the moment when the earthquake struck the area until the time that the restoration of affected area was completed to certain extent.
The state of emergency in the Great East Japan Earthquake was lifted and downgraded to an alert on July 11, the 121st day after the occurrence of the earthquake. The record shows that it was the 87th day after the occurrence of the earthquake in case of the Great Hanshin earthquake 18 years ago. This means that we had the state of emergency for nearly one month longer than we did in the Great Hanshin earthquake.
Events and topics in other part of Japan were also included in the sequence.

※Events on March 11 and 12 were recorded in hours and minutes.
