What the record holds

It was also the deadliest: NOAA records 1,319 deaths for it. NOAA’s list of significant earthquakes has 5 here, back to 1843. NOAA records deaths in 8 of the events here, 1,377 in all. The latest on NOAA’s list is a magnitude 6.7 on September 5, 2011 (68 km WSW of Kabanjahe, Indonesia). NOAA’s record here begins on January 5, 1843 with an earthquake. 2 of the 5 significant earthquakes NOAA lists here came before 1927. NOAA lists one tsunami that began within 100 km of Subulussalam, and 3 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 3.3 m, on March 28, 2005. The deadliest here came on February 16, 1861 from a magnitude 8.5 earthquake (Sw. Sumatra): NOAA’s runup records count 20 deaths within 100 km of Subulussalam. NOAA lists 10 significant eruptions of one volcano within 100 km of Subulussalam.

The events

Good to know

  • An event counts for Subulussalam 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.
