What the record holds

The deadliest was not the strongest: an earthquake on May 22, 1782 (Tainan), for which NOAA records 40,000 deaths. NOAA’s list of significant earthquakes has 49 here, back to 1604. NOAA records deaths in 43 of the events here, 52,874 in all. The latest on NOAA’s list is a magnitude 7.4 on April 2, 2024 (15 km S of Hualien City, Taiwan). NOAA’s record here begins on December 29, 1604 with an earthquake (Fujian Province: Off Coast). It grows thinner going back: 28 of the 49 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 5 tsunamis that began within 100 km of Taichung. The highest water NOAA records here was 1 m, on April 2, 2024.

Good to know

  • An event counts for Taichung 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.
