ABOUT JMA
The Japan Meteorological Agency operates over 4,000 seismic stations and monitors all 111 active volcanoes in Japan. This app uses JMA public data but is not affiliated with JMA or the Japanese government. It is not a substitute for J-Alert or any official warning system — in an emergency, always follow your local authorities.
Free with ads. Premium unlocks custom watch zones, per-zone thresholds, and nationwide hazard maps, and removes all ads. Safety shouldn't be a luxury — Premium is priced to stay accessible to everyone.
