What the record says
NCEI’s account, from the sources it cites.
Due to the deployment of autonomous bottom hydrostatic pressure gauge recorders in the bays of Shikotan and Kunashir islands, data were recorded on the most significant meteotsunami in Russia’s Far East region (the oscillation range was 1.9 m in Dimitrova Bay, which is the largest instrumentally recorded value). This event was caused by a rapidly moving (together with a cyclone) atmospheric front in the northeastern direction, the pressure jump in which was 7 hPa. Intense oscillations in the bays of the South Kuril Islands continued for several hours mainly at resonance frequencies. They posed a hazard comparable to moderate seismic tsunamis. (reference #14028)
Every runup
Nearest the source first. Heights are above sea level at the time; a tide gauge reads half the wave’s full height.
