The United States Geological Survey said the earthquake's depth, focal mechanism, and location suggest a likely source within the subducting Gorda plate. [4] Despite being centered offshore, the fault that triggered the quake travelled onshore and ruptured northeasternwards.
United States Geological Survey marker on the summit of Maiden Peak (Washington) While much less expensive to compile and produce, the revised digital U.S. topo maps have been criticized for a lack of accuracy and detail in comparison to older generation maps based on aerial photo surveys and field checks.

The "Final 2023 Critical Materials List" was determined by the United States Department of Energy (DOE), [5] with the Undersecretary for Science and Innovation involvement. . This list incorporates materials deemed critical for energy applications and minerals from the 2022 final list designated by the Department of the Interior through the United States Geological Survey (USG

The United States Geological Survey said that earthquakes of this size typically rupture over an area measuring 90 km (56 mi) x 40 km (25 mi). A majority of coseismic slip occurred directly beneath land rather than offshore with a maximum displacement at 1.2 m (3 ft 11 in). [4]
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 earthquake measured M ww 6.1 by the United States Geological Survey, [3] while the Kandilli Observatory, and AFAD measured it at M w 6.0 and 5.9 respectively. [1] [4] The earthquake was the result of strike-slip faulting at shallow depth, within the crust.
