Earthquakes near Tijuana, 1927–2026

It was also the deadliest: NOAA records 3 deaths for it. 4 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 2 of the events here, 5 in all. The latest on NOAA’s list is a magnitude 7.2 on April 4, 2010 (The 2010 Sierra El Mayor, B.C., Mexico Earthquake). NOAA lists 5 tsunamis from elsewhere that reached the coast within 100 km of Tijuana with deaths or a metre of water or more. The highest water NOAA records here was 1.23 m, on May 22, 1960.

• An event counts for Tijuana 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.
