WAJIMA, Japan >> Thousands of people made homeless overnight are living in weariness and uncertainty on the western coast of Japan a week after a powerful earthquake left at least 168 dead and dozens missing.

The rescue effort since the magnitude 7.6 New Year’s Day quake has drawn thousands of troops, firefighters and police who picked through collapsed buildings today hoping to find survivors.

Authorities warned of the danger of landslides, exacerbated by a heavy snowfall, throughout the quake’s epicenter on the Noto Peninsula in Ishikawa prefecture. The landscape blanketed in snow revealed burned and crumbled houses, ashen blocks of a city, highways with gaping holes and cracks.

The deaths included 70 people in Wajima, 70 in Suzu, 18 in Anamizu and the rest were spread among four other towns. At least 323 people were still unaccounted for, a jump from about 100 earlier in the day as rescuers pour over a list of the region’s population. Another 565 people were injured, and 1,390 homes were destroyed or seriously damaged.

A tsunami of several feet followed the initial major quake, adding to the damage. Aftershocks have continued daily.

Japanese meteorological officials warned strong quakes could persist for another month. Their frequency, while gradually diminishing, remained high compared to past quakes, totaling more than 1,000.

For the residents, recovery work has barely started. Shuji Yoshiura, a fisherman, said his boats were damaged and he could not go out on the sea.

Before the quake, Wajima was a tourist town with a shopping street offering seafood and traditional crafts. Much of it was destroyed in the fires that broke out after the Jan. 1 disaster.

Kentaro Mitsumori, who runs a corner grocery shop, slept in his car with his wife to guard against looting. Their store still stands but has no lock, electricity or running water. Everything sold out in three days. But he plans to close his business.

“Even if I manage to fix up the place, there just aren’t going to be enough customers. I don’t know how Wajima can survive,” he said.

Nearly 30,000 people staying in schools, auditoriums and other evacuation centers worried about infections as cases of COVID-19 and other illnesses popped up.

In the shelters, people were still sleeping on cold floors. After initial help of a piece of bread and a cup of water for each person a day, more aid is allowing some facilities to begin serving hot food cooked in huge pots.

People were delighted by the temporary bathing facilities set up by soldiers, sitting in the hot water they had missed for days.

Still, exhaustion and stress are wearing them down. Many are in mourning. The main quake struck on New Year’s Day, a time for families to gather in Japan. Some survivors said they were all alone because they lost their loved ones.

Mizue Kaba, 79, was lucky she survived, as did her daughter, son-in-law and grandson, who were visiting on New Year’s from Osaka in central Japan.

Kaba is sleeping at a school, and no one is sure what might happen when schools open in a week after the New Year’s break.

Three stoves were not enough to heat the school’s big hall, and more heaters arrived.

“It’s so cold,” Kaba said.
