Good to know
- An event counts for Petropavlovsk-Kamchatsky 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.
