Earthquakes near Trujillo through history

The deadliest was not the strongest: a magnitude 7.9 on May 31, 1970 (34 km SW of Chimbote, Peru), for which NOAA records 66,794 deaths. NOAA’s list of significant earthquakes has 6 here, back to 1619. NOAA records deaths in 5 of the events here, 68,719 in all. The latest on NOAA’s list is a magnitude 7.5 on February 21, 1996 (123 km WSW of Puerto Santa, Peru). NOAA’s record here begins on February 14, 1619 with an earthquake (Trujillo, Piura, Santa). 4 of the 6 significant earthquakes NOAA lists here came before 1927. NOAA lists one tsunami that began within 100 km of Trujillo, and 4 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 3.76 m, on February 21, 1996. The deadliest here came on November 20, 1960 from a magnitude 6.8 earthquake (N. Peru): NOAA’s runup records count 63 deaths within 100 km of Trujillo.

• An event counts for Trujillo 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.
