Weekly Earthquake Information 2022.12.4 Multiple Earthquakes in Noto Peninsula, Ishikawa Prefecture Great Inland Canada Earthquake – Weather News

At around 17:07 on November 30 (Wednesday), an earthquake with an estimated magnitude of 4.4 and a depth of 14 km occurred with its epicenter in the Noto region of Ishikawa Prefecture. This earthquake recorded a maximum seismic intensity of 3 in Suzu City and Noto City, Ishikawa Prefecture. The earthquake mechanism is analyzed as a reverse fault type with a pressure axis in the north-northwest-southeast direction.

The earthquake in the Noto region of Ishikawa prefecture has continued seismic activity since last spring. There were 15 earthquakes felt in November, up from October. An earthquake with a maximum seismic intensity of 4 also occurred on November 14 and the activity is quite active.

While this activity is believed to be related to subsurface distributed fluids, the detailed mechanism is not yet clearly understood. There is no tendency for activity to slow down, so watch out for strong tremors in Suzu city, which is close to the epicenter.

There were no earthquakes of magnitude 6 or greater according to analysis by the United States Geological Survey. The largest quake had a magnitude of 5.9 on the Mid-Atlantic Ridge.

On the morning of November 30 (Wednesday), Japan time, an earthquake with an estimated magnitude of 5.3 and a depth of about 10 km occurred in inland Canada. The seismic mechanism is analyzed as a reverse fault with a pressure axis in the north-northeast-south-southwest direction. Although there is believed to have been a strong quake near the epicenter, it was far from the residential area, so there was no particular impact.

Most earthquakes that occur in Canada occur on the west coast near the boundary between the Pacific and North American plates. There are very few earthquakes in inland areas, and one earthquake of magnitude 4.5 or greater that occurred near the epicenter this time was in 2015. Earthquakes larger than 5 occasionally occur, but it is a region where it is unlikely large-scale earthquakes occur that cause serious damage.
