Weekly earthquake data 2024.6.2 Seismic depth 4 centered in Kumamoto space, Kumamoto Prefecture, for the primary time in two years

At roughly 4:46 on Friday, Could 31, an earthquake estimated to have a magnitude of 4.7 and a depth of 13 km occurred with its epicenter within the Kumamoto space of ​​Kumamoto Prefecture. Because of this earthquake, shaking with a seismic depth of 4 was felt in Yatsushiro Metropolis, Uki Metropolis, Kami-Amakusa Metropolis, Kumamoto Prefecture, and Nagashima City, Kagoshima Prefecture, and tremors with a seismic depth of three on the seismic. an intense scale was noticed from Kumamoto Prefecture to Nagasaki Prefecture and Kagoshima Prefecture.

That is the primary earthquake with a seismic depth of 4 or larger within the Kumamoto area of Kumamoto Prefecture, with the earthquake with a decrease seismic depth of 5 decrease that occurred in June 2022, and the primary as soon as in about two years. The mechanism of the earthquake is being investigated to be strike-slip sort.

The epicenter of this earthquake was inside the lively space of ​​the 2016 Kumamoto Earthquake, and primarily based on the depth and mechanism of the epicenter, it seems to be exercise on or across the Hinagu Fault.

The sturdy shaking of the Kumamoto earthquake was primarily brought on by the Futagawa fault zone, whereas the close by Hinagu fault didn’t transfer a lot. The federal government’s Headquarters for the Promotion of Earthquake Analysis estimates that the chance of an earthquake better than magnitude 7 on the Hinagu fault inside 30 years is about 0% to six% within the Hinagu area, and about 0% to 16% within the Yatsushiroumi area. .

The chance of an earthquake occurring within the Yatsushiroumi area is among the many highest amongst lively fault zones in Japan, so it’s essential to arrange for earthquakes.

Close to the middle of this earthquake, the Philippine Sea plate is subducting into the Earth’s plate. The plate boundary is considered about 30km deep, and this earthquake occurred deeper than that.

Moreover, the mechanism of the earthquake was a sort of regular faulting, relatively than the kind of reverse faulting anticipated at plate boundaries, so it seems to have occurred alongside a- contained in the Philippine Sea Plate.

The 1968 magnitude 6.6 earthquake was additionally estimated at a depth of 39km, and had related mechanisms presently.

The federal government’s Central Earthquake Analysis Promotion Workplace says that no adjustments had been noticed because of the earthquake on Wednesday the seventeenth that will have elevated the Nankai Trough’s mega earthquake potential.

At roughly 4:02 on Saturday, June 1, an earthquake estimated to have a magnitude of 4.5 and a depth of roughly 40km occurred with the epicenter within the Bungo Channel. Because of this earthquake, a most seismic depth of 4 was noticed in Sukumo Metropolis, Kochi Prefecture, and a seismic depth of three was noticed in Uwajima Metropolis, Matsuno Metropolis, Kihoku Metropolis, and Ainan Metropolis in Ehime Prefecture.

The mechanism of the earthquake is studied as a sort of regular fault with a compression axis operating northwest-southeast. That is the primary earthquake of magnitude 4 or larger within the Bungo Channel in about two months.

The epicenter of this earthquake is sort of similar in location and mechanism to the magnitude 6.6 earthquake that occurred on April 17, with a most seismic depth of just below 6, so it seems to be a sequence of occasions it’s. At the moment, there are nonetheless many earthquakes, so we should proceed to watch out about earthquakes with a seismic depth of three to 4.

At roughly 20:00 on the twenty third (Thursday), an earthquake estimated at magnitude 4.6 and a depth of 48 km occurred with its epicenter off the southeast coast of Nemuro Peninsula. Because of this earthquake, the best seismic depth of three was noticed in Nemuro Metropolis, Betsukai Metropolis, and Hamanaka Metropolis, Hokkaido.

The mechanism of the earthquake is investigated as a sort of reverse fault with a stress axis within the northwest-southeast course. In January this 12 months, there was a magnitude 4.8 earthquake off the southeast coast of Nemuro Peninsula with a close-by epicenter, with a seismic depth of three.

The southeast coast of Nemuro Peninsula is an space the place earthquakes usually happen close to the boundary the place the Pacific plate crosses with the North American plate. Giant earthquakes have additionally occurred, together with a magnitude 7.0 earthquake in January 2000.

The federal government’s Central Workplace for the Promotion of Earthquake Analysis has estimated that there’s an 80% probability of an earthquake with a magnitude of seven.8 to eight.5 occurring inside 30 years within the space off the coast of Nemuro, which embrace the middle of this earthquake, so preparation is crucial. .

In accordance with a research by the US Geological Survey, there have been three earthquakes with a magnitude of 6 or larger. The most important earthquake occurred close to Tonga within the South Pacific with a magnitude of 6.6.

Within the early hours of Monday, Could 27, Japan time, an earthquake with a magnitude of 6.6 and a depth of about 127 km occurred with its epicenter within the waters north of Tonga. The mechanism of the earthquake is studied as a sort of reverse fault with a stress axis operating from west-northwest to south-east. As a result of the epicenter was a bit removed from the island and the epicenter was deep, there was no impact from the earthquake or the tsunami.

The world round Tonga is on the boundary between the Pacific plate and the Australian plate, and is an space the place many giant earthquakes happen. There are additionally many deep earthquakes with a depth of 100 km or extra, and final June there was a 7.2 magnitude earthquake simply south of this time, and in Could a 7.6 magnitude earthquake occurred within the north.

On the night time of the fifth (Friday, Japan time), an earthquake that was estimated to have a magnitude of 4.8 and a depth of about 5 km occurred with its epicenter in New Jersey, close to New York. The earthquake mechanism is taken into account to be strike-slip.

This earthquake is believed to have brought on shaking of magnitude IV on the revised Mercalli depth scale, even in central New York. Though a exact comparability just isn’t potential, the shaking corresponds to a seismic depth degree of 1 to 2 on the Japanese seismic depth scale.

Earthquakes are uncommon within the northeastern United States, together with the New York space, and solely 40 earthquakes of magnitude 3 or larger have occurred inside 250 km of the epicenter. -average just lately since 1950. Amongst them, this magnitude 4.8 is the most important.

As well as, a magnitude 5.8 earthquake that occurred in Virginia in August 2011 is named an earthquake that brought on tremors in New York and different areas.
