NOAA records deaths in 12 of the events here, 3,750 in all. The latest on NOAA’s list is a magnitude 6.1 on April 22, 2019 (3 km WSW of San Francisco, Philippines). NOAA lists 2 tsunamis that began within 100 km of Malolos, and one from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 4.7 m, on September 28, 1965. The deadliest, on September 28, 1965, killed 355 people here by NOAA’s runup records. NOAA lists 6 significant eruptions of 2 volcanoes within 100 km of Malolos. The largest was Pinatubo on June 15, 1991, at 6 on the volcanic explosivity index. It killed 800 people by NOAA’s count.

Good to know

  • An event counts for Malolos 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.
