Earthquakes near Yonago, 1927–2026

The deadliest of them was a magnitude 7 on March 7, 1927 (15 km E of Toyooka, Japan), for which NOAA records 3,022 deaths. 7 earthquakes here in these years are on NOAA’s list of significant earthquakes. NOAA records deaths in 2 of the events here, 4,422 in all. The latest on NOAA’s list is a magnitude 5.7 on April 8, 2018 (Shimane Prefecture). NOAA lists 4 tsunamis from elsewhere that reached the coast within 100 km of Yonago with deaths or a metre of water or more. The highest water NOAA records here was 3 m, on May 26, 1983.

• An event counts for Yonago 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.
