A strong and shallow earthquake registered by the USGS as M6.5 hit Kuril Islands at 09:15 UTC on December 28, 2023. The agency is reporting a depth of 23.8 km (14.8 miles). EMSC is reporting M6.5 at a depth of 13 km (8 miles).
Japan’s Izu Islands and parts of the Pacific Coast near Tokyo experienced tsunami waves up to 60 cm (2 feet) in height triggered by a shallow M5.0 earthquake that occurred at 20:26 UTC on October 8, 2023 (05:26 local time, October 9). The quake’s epicenter was situated near the uninhabited Torishima Island at the southern end of the Izu chain and is part of an ongoing earthquake swarm in the region.
A strong and shallow earthquake registered by the JMA as M6.3 hit Izu Islands, Japan at 01:31 UTC on October 6, 2023. The agency is reporting a depth of 10 km (6.2 miles). USGS and EMSC are reporting M6.1 at a depth of 10 km.
A strong and shallow earthquake registered by the JMA as M6.6 hit Izu Islands, Japan at 01:59 UTC on October 5, 2023. The agency is reporting a depth of 10 km (6.2 miles). The USGS is reporting M6.1 at a depth of 10 km (6.2 miles); EMSC M6.1 at a depth of 9 km (5.6 miles).

An intense earthquake swarm that began around the end of 2019 in the northeastern Noto Peninsula, Japan, has been tied to fluids released by ancient, or possibly unknown modern, magmatic activity. This finding, published in JGR Solid Earth, challenges previous assumptions that such seismic activity could not occur in areas devoid of volcanic activity for over 10 million years.
A strong earthquake registered by the JMA as M6.2 hit Hokkaido, Japan at 09:54 UTC on June 11, 2023. The agency is reporting a depth of 140 km (87 miles). USGS is reporting M5.2 at a depth of 123 km (76 miles), EMSC M6.2 at a depth of 112 km (69 miles).
A strong earthquake registered by the JMA as M6.2 hit near the east coast of Chiba Prefecture, Japan at 10:03 UTC (19:04 JST) on May 26, 2023. The agency is reporting a depth of 50 km (31 miles). USGS is reporting M6.2 at a depth of 44.2 km (27.5 miles); EMSC M6.1 at a depth of 60 km (37.3 miles).
A very strong and shallow earthquake registered by the JMA as M6.5 hit near the west coast of Ishikawa, Honshu, Japan at 05:42 UTC (14:42 LT) on May 5, 2023.
