What the record holds

It was also the deadliest: NOAA records 549 deaths for it. 4 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 22 of the events here, 1,425 in all. NOAA lists 4 tsunamis from elsewhere that reached the coast within 100 km of Ueda with deaths or a metre of water or more. The highest water NOAA records here was 7.23 m, on January 1, 2024. NOAA lists 20 significant eruptions of 7 volcanoes within 100 km of Ueda. The largest was Asamayama on August 20, 1930, at 3 on the volcanic explosivity index. The deadliest was Akagisan on September 16, 1947, which killed 699 people by NOAA’s count.

Good to know

  • An event counts for Ueda 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.
