Aftershocks of the Honshu, Japan Earthquake – March 13, 2011


The BC-ESP recorded many aftershocks of the March 11th Japan earthquake.
For a list of aftershocks with magnitudes 5.0 and larger visit the US Geological Survey report.

The east coast of Honshu, Japan will continue to feel earthquakes for quite some time.
Over 80 aftershocks have occurred with magnitudes over 5.0 in the past few days alone.

The U.S.G.S. defines aftershocks to be, “earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock. Aftershocks can continue over a period of weeks, months, or years. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue.”
