In addition, shaking with a seismic intensity of 3 was observed in Tokyo, Kanagawa Prefecture, Chiba Prefecture, Saitama Prefecture, Gunma Prefecture, Tochigi Prefecture, and Ibaraki Prefecture. In addition, tremors with a seismic intensity of 2 or 1 were observed over a wide area in Kanto-Koshinetsu, the Izu Islands, Shizuoka Prefecture, Fukushima Prefecture, and Miyagi Prefecture. There is no tsunami caused by this earthquake.

Restoration work continues even after notification that the elevator has stopped working

According to Elevator Systems, a company that manages elevators in Tokyo and other areas, as of 10:30 a.m., there have been 10 calls from Tokyo and Kanagawa prefectures, where tremors of magnitude 4 were observed, that elevators have stopped working, mainly in condominiums. About 20 cases have been reported, meaning that workers are heading to the site to carry out restoration work.

According to the company, elevators are supposed to automatically stop when a certain level of shaking, such as a magnitude 4 earthquake, is observed, and there is currently no information that anyone is trapped.

Inside the Tokaido Shinkansen train that came to an emergency stop

This is a video taken of the inside of a Tokaido Shinkansen train that was brought to an emergency stop due to a power outage after the earthquake.

According to the photographer, the Shinkansen was traveling between Shinagawa Station in Tokyo and Shin-Yokohama Station in Kanagawa Prefecture around 9 a.m. when the power suddenly went out and the train slowed to a stop on the tracks.

As for the shaking caused by the earthquake, I only felt a slight tremor immediately after I stopped the train.

During the power outage, only the emergency lights near the entrance and exit of the train were on, but about 10 minutes after the train stopped, it was announced that the cause was an earthquake, and the train resumed operation.

Expert on earthquake mechanism: ``Earthquakes can always occur in the Tokyo metropolitan area''

Regarding this earthquake, Professor Emeritus Nao Hirata of the University of Tokyo, who is familiar with the mechanism of earthquakes, said, ``The epicenter announced by the Japan Meteorological Agency was Tokyo Bay, but the nearby northwestern part of Chiba Prefecture is a place with relatively high seismic activity. The epicenter of the earthquake was in Tokyo Bay because it was shifted slightly to the west."

He added, ``Although this time the maximum seismic intensity was 4, earthquakes with even stronger shaking are always likely to occur in the Tokyo metropolitan area.I hope people will continue to prepare on a daily basis, such as securing furniture and stocking up on water and food.''
