The death toll from the 6.7-magnitude, pre-dawn quake was likely to rise as rescuers searched houses buried by landslides.

About 33 people were missing and 300 were injured, public broadcaster NHK said.

The quake was the latest in a string of natural disasters to batter Japan after typhoons, flooding and a record-breaking heat wave within the past two months.

Aerial footage showed dozens of landslides exposing barren hillsides near the town of Atsuma in southern Hokkaido, with mounds of red earth and toppled trees piled at the edge of green fields.

The collapsed remains of what appeared to be houses or barns were strewn about.

“It came in four big jerks – boom! boom! boom! boom!” one unidentified woman told NHK. “Before we knew it our house was bent and we couldn’t open the door.”

Prime Minister Shinzo Abe said 25,000 Self-Defense Force troops would be deployed for rescue operations.

The island, a tourist destination known for its mountains, lakes and seafood, lost its power when Hokkaido Electric Power Co shut down of all its fossil fuel-fired power plants after the quake as a precaution.

It was the first time since the utility was established in 1951 that had happened.

Almost 12 hours later, power was restored to parts of Sapporo, Hokkaido’s capital, and Asahikawa, its second-biggest city.

The government said there was damage to Hokkaido Electric’s Tomato-Atsuma plant, which supplies half the island’s 2.95 million households. It could take a week to restore power fully to all residents, Industry Minister Hiroshige Seko said.

All trains across the island were halted.

Television footage from Sapporo showed crumbled roads and mud covering a main street. Police directed traffic because signal lights were out while drink-vending machines, ubiquitous in Japan, and most ATMs were not working.

“Without electricity, there’s nothing I can do except to write prescriptions,” a doctor in Abira, the town next to Atsuma, told NHK.

Media reported a baby girl at a Sapporo hospital was in critical condition after the power was cut to her respirator. It wasn’t clear if the hospital had a generator.

The quake hit at 3:08 a.m. at a depth of 40 km, with its epicenter about 65 km southeast of Sapporo, according to the Japan Meteorological Agency. In Atsuma, it registered a 7 on Japan’s 7-point quake intensity scale, the agency said, revising an earlier measurement.

Hokkaido’s main airport was closed, at least for the day. Debris and water could be seen on the terminal floors.

Kyodo news agency said more than 200 flights and 40,000 passengers would be affected on Thursday alone.

Farming, tourism and other services are big economic drivers on Hokkaido, which accounts for just 3.6 percent of Japan’s gross domestic product, but there is some industry. Kirin Brewery and Sapporo Breweries both said factories were shut by the power outage.

A series of smaller shocks followed the initial quake, the JMA said. Residents were warned to take precautions.

By the afternoon, backhoes and other earth-moving equipment in Atsuma had begun clearing debris.

Hokkaido’s Tomari nuclear power station, which has been shut since the 2011 earthquake and tsunami, suffered a power outage but officials said it was cooling its spent nuclear fuel safely.
