TOKYO – A powerful earthquake that hit Japan on New Year’s Day killed at least 55 people, with rescue teams struggling in freezing temperatures on Jan 2 to reach isolated areas, where many people are feared trapped under toppled buildings.

In Suzu, a coastal town of just over 5,000 households near the quake’s epicentre, 90 per cent of houses may have been destroyed, according to its Mayor Masuhiro Izumiya. “The situation is catastrophic,” he said.

The quake with a preliminary magnitude of 7.6 struck in the afternoon of Jan 1, prompting people in some western coastal areas to flee to higher ground as tsunami waves swept cars and houses into the water.

Around 200 tremors have been detected since the quake first hit, according to the Japan Meteorological Agency, which warned that more strong shocks could hit in the coming days.

A coast guard aircraft en route to deliver aid to the quake-hit region collided with a commercial plane at Tokyo’s Haneda Airport on Jan 2, killing five coast guard crew, while all 379 on board the Japan Airlines flight miraculously escaped a fire.

Prime Minister Fumio Kishida said the extent of the quake damage was becoming “increasingly clear” more than 24 hours after it struck on the Noto peninsula in Ishikawa prefecture.

“The government has deployed emergency rescue teams from the Self-Defence Forces, police and fire departments to the area, and is doing its utmost to save lives and rescue victims and survivors. But we have received reports that there are still many people waiting to be rescued under collapsed buildings.”

Mr Kishida said some 3,000 rescuers were finding it difficult to reach the northern tip of the peninsula, where helicopter surveys had discovered many fires and widespread damage to buildings and infrastructure.

There are around 120 cases of people awaiting rescue, his government spokesperson said.

Situated on the Ring of Fire arc of volcanoes and oceanic trenches that partly encircles the Pacific Basin, Japan accounts for about 20 per cent of the world’s earthquakes of magnitude 6 or greater, and each year experiences up to 2,000 quakes that can be felt.

Many rail services and flights into the area have been suspended. More than 500 people were stranded at Noto’s airport, which closed owing to cracks in its runway and access road, and damage to its terminal building.

The authorities have confirmed 55 deaths, all in Ishikawa prefecture, making it Japan’s deadliest earthquake since 2016.

Many of those killed were in Suzu and Wajima, another city on the remote northern tip of the Noto peninsula.

Scores more have been injured, and the authorities were battling blazes in several cities on Jan 2 and hauling people from collapsed buildings.

Wrecked homes

“I’ve never experienced a quake that powerful,” said Wajima resident Shoichi Kobayashi, 71, who was at home having a celebratory New Year’s meal with his wife and son when the quake struck, sending furniture flying across the dining room.

“Even the aftershocks made it difficult to stand up straight,” he said, adding that his family members were sleeping in their car because they could not return to their badly damaged home.

Ms Fujiko Ueno, a 73-year-old resident of Nanao city in Ishikawa, said nearly 20 people were in her house for a New Year celebration when the quake struck, splintering the walls, which came crashing down on a parked car.

Miraculously, no one was hurt.

“It all happened in the blink of an eye,” she said, standing next to the crushed car on a road littered with debris and mud that oozed out from cracks in its surface.

Several world leaders sent condolence messages, with President Joe Biden saying in a statement that the United States was ready to provide any necessary help to Japan.

The Japanese government ordered around 100,000 people to evacuate their homes on the night of Jan 1, sending them to sports halls and school gymnasiums, commonly used as evacuation centres in emergencies.

Almost half of those evacuated had returned to their homes on Jan 2 after the authorities lifted tsunami warnings.

But around 33,000 households remained without power in Ishikawa prefecture on the morning of Jan 2 after a night when temperatures dropped below freezing, according to Hokuriku Electric Power’s website.

Nearly 20,000 homes have no water supply.

Nuclear plants

The quake also comes at a sensitive time for Japan's nuclear industry, which has faced fierce opposition from some locals since the 2011 earthquake and tsunami that triggered nuclear meltdowns in Fukushima on the eastern coast.

Whole towns were devastated in that disaster and nearly 20,000 people died.

Japan last week lifted an operational ban imposed on the world’s biggest nuclear plant, Kashiwazaki-Kariwa, which had been offline since the 2011 tsunami.

The Nuclear Regulation Authority said no irregularities were found at nuclear plants along the Sea of Japan, including five active reactors at Kansai Electric Power’s Ohi and Takahama plants in Fukui prefecture.

Hokuriku Electric’s Shika plant, the closest to the epicentre, has also been idled since 2011. The company said there had been some power outages and oil leaks following Jan 1’s jolt but no radiation leakage.

The company had previously said it hoped to restart the reactor in 2026.

Toshiba said its local subsidiary Kaga Toshiba Electronics has stopped semiconductor production at its plant in Ishikawa to gauge the quake’s impact on its facilities.

Chip equipment maker Kokusai Electric said it found damage at its factory in Toyama and was investigating further, ahead of the planned resumption of operations on Jan 4. REUTERS
