What the record holds

The deadliest was not the strongest: a magnitude 8 on September 1, 1923 (Tokyo, Yokohama), for which NOAA records 105,385 deaths. NOAA’s list of significant earthquakes has 32 here, back to AD 799. NOAA records deaths in 20 of the events here, 153,827 in all. The latest on NOAA’s list is a magnitude 7.3 on March 16, 2022 (57 km ENE of Namie, Japan). NOAA’s record here begins on September 18, 799 with a tsunami (Kashima, Japan). It grows thinner going back: 11 of the 32 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Utsunomiya, and 10 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 15.24 m, on March 11, 2011. The deadliest here came on November 4, 1677 from a magnitude 7.4 earthquake (Off Se. Boso Peninsula): NOAA’s runup records count 116 deaths within 100 km of Utsunomiya. NOAA lists 4 significant eruptions of 2 volcanoes within 100 km of Utsunomiya. The largest was Nasudake on March 5, 1410, at 3 on the volcanic explosivity index. It killed 180 people by NOAA’s count.

Good to know

  • An event counts for Utsunomiya 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.
