M5.5 earthquake hits northeastern Japan, no tsunami warning issued
The 2:23 am earthquake with its focus at a depth of 43 kilometers outside Aomori prefecture registered a lower 5 on the Japanese seismic intensity scale of 7 in Morioka, Iwate prefecture, a level of shaking described as frightening to many people and creates a need to hold onto something stable, the Japan Meteorological Agency said.
The strength of the temblor was adjusted upwards from the initially reported magnitude 6.3.
The quake was also felt in part of Hokkaido, Japan’s northernmost main island. There were no direct reports of injuries or major damage from the construction.
No anomalies were found in the nuclear power plants and connected facilities in the region.
While there may be minor sea level changes in the Pacific coastal region of northeastern Japan, there is no risk of a tsunami, the agency added.
