About quake-monitor

quake-monitor shows earthquake information for Japan derived from Japan Meteorological Agency (JMA) bulletins: recent earthquakes on a map, JMA seismic intensity by prefecture, and tsunami warnings and advisories, with guidance on what to do. It is an independent site, not an official government service; in an emergency, follow official instructions. This page explains where Japan's official earthquake and tsunami information comes from and how to read JMA seismic intensity and tsunami categories.
