Rescuers with dogs search for survivors after deadly Hokkaido quake

Rescue workers with dogs searched for survivors on Friday in debris-strewn landslides caused by an earthquake in Japan's northern island of Hokkaido, as electricity was restored to just over half of households.

Rescue workers with dogs searched for survivors on Friday in debris-strewn landslides caused by an earthquake in Japan's northern island of Hokkaido, as electricity was restored to just over half of households.

Public broadcaster NHK put the death toll at 12, with five people unresponsive. Earlier, Prime Minister Shinzo Abe said 16 had died, but Chief Cabinet Secretary Yoshihide Suga later clarified in updated numbers that nine had been confirmed dead and nine others were in a state of cardiopulmonary arrest, a term typically used before death is confirmed.

Another 24 were still missing after Thursday's pre-dawn magnitude 6.7 quake, the latest deadly natural disaster to hit 
Japan over the past two months, coming after typhoons, floods and a record-breaking heat wave.

Nearly 5,000 people spent the night in evacuation centres where food was distributed in the morning.

"It was an anxious night with several aftershocks, but we took encouragement from being together and now we're grateful for some food," one woman told NHK.

22,000 rescue workers

Prime Minister Shinzo Abe told an emergency meeting early on Friday that 22,000 rescue workers had worked through the night to search for survivors.

With rain forecast for Friday afternoon and Saturday, he urged people to be careful about loose soil that could cause unstable houses to collapse or further landslides.

"We will devote all our energy to saving lives," Abe said.

Hokkaido Electric Power Co. aimed to bring more than 80 per cent of the 2.95 million households back online by the end of Friday, industry minister Hiroshige Seko said.

Dozens of landslides

Flights resumed from midday at Hokkaido's main airport, New Chitose, with more flights planned for the afternoon, airline officials said.

Soldiers in fatigues and orange-clad rescue workers searched for survivors, picking through debris on huge mounds of earth near the epicentre in Atsuma in southern Hokkaido. Aerial footage showed rescuers with dogs walking through the destruction.

All 24 of the missing people are from the Atsuma area, where dozens of landslides wrecked homes and other structures and left starkly barren hillsides.

Full blackout

"I just hope they can find him quickly," one unidentified man told NHK as he watched the search for his missing neighbour.

The quake damaged the big Tomato-Atsuma plant, which normally supplies half of Hokkaido's power and is located near the epicentre, forcing it to automatically shut down. That caused such instability in the grid that it tripped all other power stations on the island, causing a full blackout.

Hokkaido Electric was bringing other smaller plants back on line and also receiving some power transferred through undersea cables from the main island of Honshu.

The quake was the second disaster to hit Japan this week alone after a summer during which the country has been battered by deadly typhoons, flooding and a record heat wave.

Airport shut down

Kansai International Airport has been shut since Typhoon Jebi ripped through Osaka on Tuesday, although some domestic flights operated by Japan Airlines (JAL) and ANA's low-cost carrier Peach Aviation resumed on Friday, the carriers said.

JR Hokkaido planned to resume bullet train operations from midday. It was also trying to resume other train services on Friday afternoon, a spokesperson said.

Manufacturers were still affected by power outages.

Toyota Motor Corp's Tomakomai factory, which makes transmissions and other parts, said operations remained suspended indefinitely until power was restored, a spokesman said.

Toppan Printing's operations at a plant in Chitose, which makes food packages, would remain suspended until it regained power, a spokesman said.

The quake prompted Japan's Self Defence Forces to cancel two joint military exercises in Hokkaido, including the first-ever drill with Australian fighter jets, and a training exercise with the U.S. Marine Corps.

A soccer friendly between Japan and Chile scheduled for Friday in Sapporo was also called off.
