Earthquakes near Trento through history

None reached magnitude 7: the strongest was a magnitude 6, twice: on April 30, 793 (Verona) and in 1001 (Verona). The deadliest was not the strongest: an earthquake on December 25, 1222 (Brescia), for which NOAA records 12,000 deaths. NOAA records deaths in 6 of the events here, 14,208 in all. The latest on NOAA’s list is a magnitude 5.1 on November 24, 2004 (Northern: Brescia). NOAA’s record here begins in AD 243 with an earthquake (Verona,Benaco). NOAA lists 4 tsunamis that began within 100 km of Trento. The highest water NOAA records here was 235 m, on October 9, 1963.

• An event counts for Trento 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.
