An earthquake with a preliminary magnitude of 5.4 struck off Japan's Miyazaki Prefecture, on the southeast coast of Kyushu Island, on Wednesday, Trend reports citing Xinhua.
According to the Japan Meteorological Agency (JMA), the temblor, which occurred at 9:11 a.m. local time, was centered in the Hyuga-nada Sea, which is part of the Pacific Ocean that lies off the eastern shore of Kyushu Island, to the southwest of the island of Honshu, off the south coast of Japan.
The JMA did not issue a tsunami warning following the offshore quake.
The quake's epicenter, specifically, was located at a latitude of 32.2 degrees north and a longitude of 132.2 degrees east, and occurred at a depth described by the JMA as "very shallow."
The earthquake logged 3 on the Japanese seismic intensity scale which peaks at 7 in some areas of Miyazaki, Kumamoto and Oita prefectures, the JMA said.
There have been no immediate reports of damage or injuries as a result of the quake.
Japan's nuclear watchdog has not issued any warnings about irregularities or abnormalities at nuclear power plants located in regions affected by the quake.
