Earthquakes near Puerto Montt, 1927–2026

NOAA lists 2 tsunamis that began within 100 km of Puerto Montt, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 60 m, on February 19, 1965. The deadliest, on February 19, 1965, killed 27 people here by NOAA’s runup records. NOAA lists 3 significant eruptions of one volcano within 100 km of Puerto Montt. The largest was Calbuco on April 22, 2015, at 4 on the volcanic explosivity index.

• An event counts for Puerto Montt 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.
