What the record holds
The strongest was a magnitude 7, twice: on September 12, 664 (Kyongju) and on June 12, 1681 (Yangyang, Sanchok). The deadliest was not the strongest: a magnitude 5.4 on September 12, 2016 (Gyeongju), for which NOAA records one death. NOAA records deaths in 2 of the events here, 2 in all. The latest on NOAA’s list is a magnitude 5.5 on November 15, 2017 (7 km SW of Heunghae, South Korea). NOAA’s record here begins in December 100 with an earthquake (Kyongju). It grows thinner going back: 2 of the 7 significant earthquakes NOAA lists here are from 1927 on.

Good to know
- An event counts for Andong 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.
