Earthquakes near Ma’anshan through history

None reached magnitude 7: the strongest was a magnitude 5.5 on April 22, 1974 (Jiangsu Province). The deadliest was not the strongest: an earthquake in December 1037 (Jiangsu Province: Taichou), for which NOAA records 22,391 deaths. NOAA records deaths in 3 of the events here, 22,448 in all. The latest on NOAA’s list is a magnitude 5.4 on July 9, 1979 (Jiangsu Province: Liyang). NOAA’s record here begins on August 4, 499 with an earthquake (Jiangsu Province).

• An event counts for Ma’anshan 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.
