Earthquakes near Sivas through history

The deadliest was not the strongest: a magnitude 7 on December 20, 1942 (Niksar, Erbaa), for which NOAA records 1,000 deaths. NOAA’s list of significant earthquakes has 5 here, back to 1916. NOAA records deaths in 2 of the events here, 1,064 in all. The latest on NOAA’s list is a magnitude 5.6 on April 18, 2024 (11 km W of Sulusaray, Turkey). NOAA’s record here begins on January 24, 1916 with an earthquake (18 km W of Doğanşar, Turkey).

• An event counts for Sivas 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.
