A magnitude 5.8 earthquake has rattled Japan's northern island of Hokkaido. There's no word of any casualties.
The quake occurred at 9:22 PM local time Thursday night at the depth of 30 kilometers in the central part of the island.
In the town of Atsuma, the tremor registered 6 minus on the country's seismic scale up to 7.
A local government official in the town says the earthquake was very strong. The individual said the shaking continued for about 10 seconds and the lights went out temporarily.
Last September, the town suffered a massive quake that killed more than 30 people.
Weather officials say they believe the tremor is an aftershock of the September one. They are warning that more jolts may follow.
The island's power company says all 3 nuclear power reactors in the prefecture have been offline and no abnormalities have been detected.
