Earthquakes near Mataram through history

It was also the deadliest: NOAA records 11,453 deaths for it. NOAA’s list of significant earthquakes has 20 here, back to 1815. NOAA records deaths in 18 of the events here, 13,233 in all. The latest on NOAA’s list is a magnitude 4.9 on September 7, 2024 (11 km NE of Ubud, Indonesia). NOAA’s record here begins on November 22, 1815 with an earthquake (Bali). It grows thinner going back: 17 of the 20 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 6 tsunamis that began within 100 km of Mataram, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 5.5 m, on August 19, 1977. The deadliest here came on August 19, 1977 from a magnitude 8.3 earthquake (Sunda Islands): NOAA’s runup records count 25 deaths within 100 km of Mataram. NOAA lists 5 significant eruptions of 3 volcanoes within 100 km of Mataram. The largest was Agung on March 18, 1963, at 5 on the volcanic explosivity index. It killed 1,028 people by NOAA’s count.

• An event counts for Mataram 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.
