Earthquakes near Toyama, 1927–2026

It was also the deadliest: NOAA records 549 deaths for it. 5 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 11 of the events here, 656 in all. The ten years with the most magnitude 6+ earthquakes were 2017–2026, with 4 of the 10. NOAA lists 3 tsunamis that began within 100 km of Toyama, and 2 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 11.34 m, on January 1, 2024. NOAA lists 7 significant eruptions of 4 volcanoes within 100 km of Toyama. The largest was Ontakesan on September 27, 2014, at 3 on the volcanic explosivity index. It killed 55 people by NOAA’s count.

• An event counts for Toyama when it began within 100 km of its centre, or 200 km for an earthquake of magnitude 7 or more. Damage can reach further.
• USGS counts here start at magnitude 6: the catalogue’s smaller quakes thin out going back, where few instruments listened.
• NOAA lists significant events only: earthquakes that killed, did about $1 million of damage, reached magnitude 7.5 or intensity X, or raised a tsunami, and eruptions and tsunamis by like measures. Magnitudes before 1900 are its estimates from written accounts.
• Deaths are NOAA’s total for each event, wherever people died, its tsunami and fires included. A tsunami counts the dead its runup records give for this place: NOAA’s total for a tsunami includes its source quake’s.
• A tsunami from elsewhere counts where one of its runups killed or rose a metre or more.
• Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
