What the record holds

None reached magnitude 7: the strongest was an estimated magnitude 6.1 on April 14, 1895 (Slovenia: Ljubljana). It was also the deadliest: NOAA records 7 deaths for it. NOAA records deaths in 3 of the events here, 9 in all. The latest on NOAA’s list is a magnitude 5.2 on July 12, 2004 (Bovec, Kobarid). NOAA’s record here begins in AD 567 with an earthquake (Slovenia). It grows thinner going back: 6 of the 25 significant earthquakes NOAA lists here are from 1927 on. NOAA lists one tsunami that began in or off Slovenia.

Good to know

  • An event counts for Slovenia when it began inside its borders, or at sea within 100 km of its coast (so one can count for two neighbours), or further out, up to 300 km, where Slovenia is the nearest country.
  • 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.
  • The map frames the box around Slovenia, its neighbours’ quakes included, so its count runs higher than this page’s.
  • Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
