Earthquakes near Victorville through history

The deadliest was not the strongest: a magnitude 6.6 on February 9, 1971 (1971 San Fernando Earthquake, California), for which NOAA records 65 deaths. NOAA’s list of significant earthquakes has 19 here, back to 1812. NOAA records deaths in 7 of the events here, 67 in all. The latest on NOAA’s list is a magnitude 7.1 on July 6, 2019 (Ridgecrest Earthquake Sequence). NOAA’s record here begins on December 8, 1812 with an earthquake (San Juan Capistrano). It grows thinner going back: 15 of the 19 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of Victorville, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 1.52 m, on May 10, 1877.

• An event counts for Victorville 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.
