No tsunami after M5.3 quake strikes near Tokyo

An earthquake with a magnitude of 5.3 occurred near Tokyo on Thursday morning. There was no tsunami.

The quake struck around 9:08 a.m. It registered lower five on the Japanese seismic scale of zero to seven in Tochigi and Saitama prefectures.

Tremors of one through four were registered in many areas from northeastern through central Japan.

Japan's Meteorological Agency says the quake was focused in southern Ibaraki Prefecture, at a depth of 46 kilometers.

Agency officials say the reverse fault quake occurred where the Philippine Sea plate slides under the overriding plate.
Tochigi Prefecture last had a lower five quake on March 16, 2022, and Saitama Prefecture on October 7, 2021.

The officials are urging caution for more tremors of up to lower five for about a week, as there is a risk of tumbling rocks and landslides in badly shaken areas.

Hirata Naoshi is a professor emeritus at the University of Tokyo and the head of a government earthquake panel. He notes that the southern Kanto region has frequently had lower five-level earthquakes.

He is urging caution for tremors on a similar scale over the next few days.
