What the record holds

The deadliest was not the strongest: a magnitude 4.5 on March 18, 2012 (Dhaka), for which NOAA records 44 deaths. NOAA’s list of significant earthquakes has 6 here, back to 1762. NOAA records deaths in 2 of the events here, 54 in all. The latest on NOAA’s list is a magnitude 5.4 on November 21, 2025 (14 km ESE of Tungi, Bangladesh). NOAA’s record here begins on April 2, 1762 with a tsunami (Northern Bay Of Bengal). NOAA lists one tsunami from elsewhere that reached the coast within 100 km of Comilla with deaths or a metre of water or more. The highest water NOAA records here was 1.83 m, on April 2, 1762.

Good to know

  • An event counts for Comilla 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.
