An earthquake with a preliminary magnitude of 6.0 struck northeastern Japan early Wednesday, but there was no threat of a tsunami, the weather agency said.

The quake occurred at 2:46 a.m., logging upper 5 on the Japanese seismic intensity scale of 7 in Hashikami, Aomori Prefecture, with the focus in the Pacific Ocean off Iwate Prefecture at a depth of about 50 kilometers, the Japan Meteorological Agency said.

At the intensity level of upper 5, many people find it hard to move and walking is difficult without holding onto something stable.

The temblor also registered lower 5 in Iwate Prefecture and part of Aomori Prefecture, according to the weather agency. The quake was also felt in some areas of Hokkaido, Japan's northernmost main island.

Following the earthquake, Tohoku Electric Power Co. said no abnormalities were found at its two nuclear power plants in Aomori and Miyagi prefectures.
