Earthquakes near Larache through history

One stands far above the rest: an estimated magnitude 7.5 on May 26, 881. The deadliest was not the strongest: an earthquake on January 29, 1909 (Tetuan (Tetouan),Romars), for which NOAA records 100 deaths. NOAA’s record here begins on May 26, 881 with an earthquake. NOAA lists one tsunami that began within 100 km of Larache, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 15.2 m, on November 1, 1755.

• An event counts for Larache 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.
