What the record holds

The deadliest was not the strongest: a magnitude 6.4 on March 11, 1933 (The 1933 Long Beach, California Earthquake), for which NOAA records 120 deaths. 13 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 2 of the events here, 123 in all. The latest on NOAA’s list is a magnitude 5.1 on March 29, 2014 (La Habra, Brea, Fullerton). NOAA lists 2 tsunamis from elsewhere that reached the coast within 100 km of Temecula with deaths or a metre of water or more. The highest water NOAA records here was 1.2 m, on May 22, 1960.

Good to know

  • An event counts for Temecula 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.
