TOKYO (Reuters) – A powerful earthquake of magnitude 6.7 on Japan’s northern island of Hokkaido caused a landslide that engulfed houses early on Thursday, injuring and trapping a number of people and cutting power in several areas.
A landslide along a long ridge in the rural town of Atsumi could be seen in aerial footage from public broadcaster NHK. Some 10 people had been taken to hospital with injuries, one of them serious, it said.
There were widespread power outages and blocked roads, NHK said, but no early reports of deaths.
The quake, which struck at 3:08 a.m. (1808 GMT on Wednesday) posed no tsunami risk, the Japan Meteorological Agency (JMA) said. The U.S. Geological Survey said it struck some 68 km (42 miles) southeast of Sapporo, Hokkaido’s main city.
Prime Minister Shinzo Abe, arriving at his office before 6 a.m., told reporters his government had set up a command center to coordinate relief and rescue. His voice sounding haggard, Abe said saving lives was his government’s top priority.
The Tomari Nuclear Power Station, shut since shortly after a massive 2011 earthquake, reported no irregularities and its fuel rods were cooling safely in a pool, operator Hokkaido Electric Power (9509.T) Co told NHK.
A series of smaller shocks, including one with a magnitude of 5.4, followed the initial temblor, the Meteorological Agency said. Agency official Toshiyuki Matsumori, at a early morning news conference, warned residents to take precautions for potential major aftershocks in coming days.
NHK showed a brick wall collapsed and broken glass in a home and quoted local police as reporting some people trapped in collapsed structures.
Japan, situated on the “Ring of Fire” arc of volcanoes and oceanic trenches that partly encircles the Pacific Basin, accounts for about 20 percent of the world’s earthquakes of magnitude 6 or greater.
On March 11, 2011, a 9.0 magnitude earthquake, the most powerful ever recorded in Japan, struck under the ocean off the coast of the northern city of Sendai. The quake set off a series of massive tsunami that devastated a wide swathe of the Pacific coastline and killed nearly 20,000.
The tsunami also damaged the Fukushima Daiichi Nuclear Power Plant, leading to a series of explosions and meltdowns in the world’s worst nuclear disaster for 25 years.
Saturday marked the 95th anniversary of the Great Kanto earthquake, which had a magnitude of 7.9 and killed more than 140,000 people in the Tokyo area. Seismologists have said another such quake could strike the city at any time.
