About: Earthquake Log

Earthquake Log collects the public earthquake lists of the Japan Meteorological Agency and the U.S. Geological Survey once a day and shows them in 14 languages, with an archive of earthquakes reported in Japan.

It does not issue forecasts, warnings or advice. Earthquake and tsunami warnings in Japan are issued only by the Japan Meteorological Agency.

This page is updated only once a day and is not an alert service. For current earthquake and tsunami information, check the Japan Meteorological Agency, the USGS and your local authorities.
