M 7.6 - 73 km ENE of Misawa, Japan https://earthquake.usgs.gov/earthquakes/eventpage/us6000rtdt/executive 2025-12-08 14:15:11 (UTC) 40.960°N 142.185°E 53.1 km depth It was however fairly deep (53.1 km depth) as compared to the Great Tohoku earthquake in which the sea floor was displaced. I don't believe a tsunami would be significant. https://earthquake.usgs.gov/earthquakes/eventpage/us6000rtdt/region-info
