Japan rocked by 2 earthquakes after typhoon

Japan rocked by 2 earthquakes after typhoon

Japan's Meteorological Agency said the epicenter of the quake, which struck at a depth of 40 kilometers, was just east of the city of Tomakomai.

"Large quakes often occur, especially within two-three days (of a big one)", said Toshiyuki Matsumori, in charge of monitoring earthquakes and tsunamis at the meteorological agency.

Japan's industry ministry added the Tomato-Atsuma plant, operated by Hokkaido Electric Power Co and located in the southern part of the island, has been damaged, without specifying the nature of the damage.

"We are merely inconvenienced here", one Twitter user in Sapporo reported.

Efforts to restore power to almost 3 million households were underway but it was not clear when supplies would be restored, a company spokesman said.

The quake left nearly three million people without power after damage to a major thermal plant supplying the region, with Industry Minister Hiroshige Seko saying it could take "at least a week" for supply to be restored.

Airports and many roads on the island are closed and trains have stopped because of the power cuts. In Sapporo, a mudslide on a road left several cars half buried.

They also write about long lines at food stores as people stock up on supplies amid fears of more tremors.

Hokkaido Electric said this is the first time since its establishment in 1951 that power has been lost across the entire island.

Japan's hot northern hemisphere summer also brought deadly hot temperatures and devastating downpours from moisture-laden air masses over Hiroshima.

Seven people are confirmed dead after the 6.7 magnitude quake caused landslides, with dozens hospitalised and millions of homes and businesses without power, according to local reports.

The hope had been to get power back up within hours and some electricity was gradually being restored.

A Japanese nuclear energy station is relying on emergency back up power after a powerful quake knocked out electricity on the northern island of Hokkaido on Thursday, Sept. 6, a stark reminder of the Fukushima disaster more than seven years ago.

The plant, which has been in shutdown since the aftermath of the Fukushima disaster, lost power soon after Thursday's quake, the government said earlier in the day.

The quake's impact was widespread.

"Only a few cartons of instant ramen were left", Mika Takeda, who lives in the town of Biei, said, according to the Associated Press.

Around 20,000 rescue workers, including police and members of the Self-Defence Forces were responding to the disaster, Suga said.
