Recent Earthquakes in Japan with Magnitude and Seismic Intensity (Japan Meteorological Agency)

jma/earthquakes

The most recent earthquakes in and around Japan from the Japan Meteorological Agency, newest first, up to 50 events from the last few days: for each the event identifier, origin time (JST, +09:00), the epicentre region in English and Japanese, magnitude, the maximum seismic intensity on the JMA shindo scale (0 to 4, then 5-, 5+, 6-, 6+, 7; null when no intensity was observed), latitude, longitude, depth in km and the bulletin type. Events without a determined hypocentre are left out. Takes no input.
