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 47 here, back to AD 745. NOAA records deaths in 33 of the events here, 167,090 in all. The latest on NOAA’s list is a magnitude 4.9 on December 17, 2009 (Honshu: Ito). NOAA’s record here begins on June 5, 745 with an earthquake (Mino). It grows thinner going back: 13 of the 47 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 16 tsunamis that began within 100 km of Shizuoka, and 14 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 13 m, on September 1, 1923. The deadliest here came on September 20, 1498 from a magnitude 8.3 earthquake (Enshunada Sea): NOAA’s runup records count 26,000 deaths within 100 km of Shizuoka. NOAA lists 10 significant eruptions of 3 volcanoes within 100 km of Shizuoka. The largest was Fujisan on December 16, 1707, at 4 on the volcanic explosivity index.

Good to know

  • An event counts for Shizuoka 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.
