On the twenty second, an earthquake with a seismic depth of decrease 5 occurred, and seismic exercise continued on the twenty third within the waters close to Niijima and Kozushima within the Izu Islands. I’m calling.
Before 5:00 pm on the twenty second, a magnitude 5.3 earthquake occurred with an epicenter within the sea close to Niijima and Kozushima within the Izu Islands.
According to the Japan Meteorological Agency, earthquakes occurred one after one other within the sea close to Niijima and Kozushima from earlier than midday on the twenty second, and the variety of earthquakes with a seismic depth of 1 or increased was noticed 29 instances on the twenty second.
Furthermore, seismic exercise continued on the twenty third, and 15 earthquakes that felt shaking had occurred by 5:00 pm, together with a seismic depth of three on Toshima simply after 4:30 am.
The Japan Meteorological Agency has stated that there have been giant earthquakes on this space up to now, adopted by earthquakes of comparable magnitude, and is looking for folks to be cautious of earthquakes accompanied by robust tremors in the meanwhile in areas the place the tremors had been robust. improve.

â–½ On the fifth, a seismic depth of 6 higher was noticed in Suzu City, Ishikawa Prefecture on account of an earthquake off the coast of Noto Peninsula.
â–½ On the fifth, a seismic depth of higher 5 occurred in Suzu City.
â–½ On the eleventh, a seismic depth of higher 5 was noticed in Kisarazu City on account of an earthquake in southern Chiba prefecture.
â–½ On the thirteenth, an earthquake close to the Tokara Islands hit Nakanoshima in Toshima Village, Kagoshima Prefecture with a seismic depth of 5 decrease.
â–½ On the twenty second, an earthquake close to Niijima and Kozushima struck with a seismic depth of lower than 5.
I believe some folks could also be questioning, “There have been a lot of earthquakes lately…” or “Is the Nankai Trough close?”
We requested Professor Takuya Nishimura of the Disaster Prevention Research Institute, Kyoto University, who focuses on crustal motion.
Q. Why are earthquakes occurring one after one other close to Niijima and Kozushima?
A.The Philippine Sea Plate collides with Honshu from the Izu Islands to the Izu Peninsula, and pressure is prone to accumulate. Large earthquakes have occurred up to now, and particularly in 2000, the eruption of Miyakejima triggered a particularly giant seismic exercise over a large space. The epicentral area of this time may be stated to be the northern finish of the quake. This is true for earthquakes within the Izu Islands on the whole, however even when the magnitude is about 5, the epicenter is shallow and near the islands, so the tremors are robust. I skilled it as soon as, however the impression was like a dump truck crashing into the inn.
Especially within the sea close to Niijima and Kozushima, seismic depth 6 decrease occurred 3 times in 2000.
In the waters close to Niijima and Kozushima, seismic exercise is energetic, as evidenced by an earthquake of magnitude 5 that shook Toshima three years in the past.
Especially in 2000, the exercise continued for about half a yr after June, and earthquakes with seismic depth 6 decrease occurred 3 times in a single month.
Q.Is it potential that this exercise will proceed like 2000?
A. One concern is that the opportunity of seismic exercise related to volcanic exercise stays. In that case, it tends to proceed for a very long time like an earthquake swarm as a result of it continues with the motion of magma. However, at this stage there is no such thing as a forecast. There are not any indicators but, however we have to have a look at crustal motion information along with seismic exercise.
Q. Is there a connection between earthquakes in numerous locations lately?
A. It’s true that there have been a sequence of earthquakes lately. However, the epicenters are removed from one another, and the mechanisms of earthquakes are additionally completely different. Relevance is tough to seek out. The Japanese archipelago is situated the place plates are pushing in opposition to one another, which makes it seem as if many locations are interlocking.
Q. On SNS, there are voices of concern concerning the relationship with the Nankai Trough megathrust earthquake.
Regarding the latest earthquake within the Izu Islands, it is very important put together for robust tremors. Fixing furnishings is one thing you are able to do near you. Avoid damage by transferring objects in excessive locations. I might additionally like folks residing in city areas to reconfirm their preparations for big earthquakes. In addition to stockpiling meals and securing ingesting water, particularly those that commute within the Tokyo metropolitan space, please think about that public transportation will cease. It can also be vital to know what to do within the occasion of an earthquake, and to verify the technique of communication.
