On March 16, 2022, at 23:36 JST, a strong earthquake struck off the coast of Fukushima, Japan.[7] The earthquake had a magnitude of 7.4 according to the Japanese Meteorological Agency (JMA), while the United States Geological Survey (USGS) gave an estimate of 7.3. Immediately after the event a 30‑cm tsunami was reported. The event is known in Japanese as Fukushima-ken Oki Jishin (福島県沖地震, lit. 'Fukushima prefecture offshore earthquake').

"Yesterday's large earthquake, M7.3, off the coast of Japan caused damage, injuries, and death – but not from a tsunami. NTWC was monitoring the event using real time data from both the deep-ocean DART network and coastal tide gauges in Japan, where the maximum reported wave height reached 1 foot. A small tsunami wave was detected offshore Japan by DARTs 21418 and 21419. The real-time ocean observations were used in the NTWC tsunami forecast model to confirm that there was no tsunami danger. The model also accurately forecasted the coastal observations from this event. (Image) Tsunami observed with a 0.4 foot wave height at Ofunato, Japan tide gauge. NTWC tsunami forecast results.
