Rescuers frantically searched for survivors on Wednesday, a day after a 7.1-magnitude earthquake shook southern Japan, killing at least 18 people, knocking out power to thousands of homes and rupturing roads across the region.
The earthquake that hit on Tuesday in the Kumamoto area on the southern main island of Kyushu also left at least 62 people injured, six of them seriously, officials said.
The tally has been steadily growing, fanning fears it may continue to rise.
The sweltering weather heightened worries about the survivors as rescuers braved the heat. It remained unclear how many people might still be missing.
Mall operator Aeon said four workers at the Kumamoto shopping centre remained unaccounted for after checks of the roughly 2,700 staff. Customers had been evacuated right after the initial quake.
The shopping centre’s second floor collapsed, trapping people. Witnesses said the explosion shook the area as much as the quake.
Three people remained missing, while four deaths were confirmed at the shopping centre site, according to Aeon.
“Even now, there are people waiting to be rescued, and this is a race against time,” Prime Minister Sanae Takaichi told reporters in Tokyo. “We will marshal all available resources on the ground to save and rescue as many people as possible.”
Hospitals were reported to be treating dozens of other patients.
Authorities are investigating a possible gas explosion at the Aeon mall. Rescuers reported smelling gas inside the building but the cause of the incident was still under investigation, said Japan’s top government spokesperson, Minoru Kihara.
“I thought a bomb had gone off,” Takateru Sonoda, 41, who runs a combined hair salon and cafe near the mall, told Jiji Press. “There were people calling on others to evacuate and sirens were ringing out. Nearby roads were gridlocked, it was a state of panic.”
Emergency fire rescue teams, police and around 170 army personnel were focusing on areas of the building where calls for help had been received. More than 4,500 soldiers have been deployed to help with recovery efforts across the quake zone.
In nearby Yatsushino, a chimney collapse at a Nippon Paper Industries factory killed five people while seven others were rescued from the debris, according to the Kumamoto prefectural government disaster team.
Four people were still believed to be trapped there, it said.
Across the prefecture, which also suffered a deadly earthquake a decade ago, around 260,000 people were instructed to go to evacuation centres, authorities said. Police said they received 386 emergency calls after the quake hit, including reports of collapsed buildings and people seeking rescue.
The quake’s epicentre was about 20 km (12 miles) south of Kumamoto City, central Kyushu’s largest city with a population of around 700,000. The quake was followed by more than 100 aftershocks.
In nearby Yatsushiro city — among the hardest-hit areas — many homes had damaged roofs and a handful of buildings collapsed. Roads leading to the coastal town were cracked and buckled in places, and many businesses remained shuttered.
Part of a bridge had collapsed into the Kumagawa River, drawing a steady trickle of curious residents to the site.
Authorities have warned residents in the areas that felt the biggest tremors to be on alert for further strong quakes for about a week, as well as for the risk of landslides. On Japan’s seismic intensity scale, Tuesday’s tremor measured the highest level of 7 in some areas.
With more than 36,000 homes still without power as temperatures soar to around 34 degrees Celsius (93 degrees Fahrenheit) on Wednesday, authorities also warned about the risk of heat stroke.
One hospital in Uki city, near the epicentre, said a power outage caused by the earthquake meant it was unable to function.
“It’s become like a field hospital,” the head of the administrative department told NHK. Another hospital in the city said it had suspended admissions as it could no longer handle additional emergency cases after accepting 86 injured people following the quake, including three with serious injuries.
Several passengers aboard high-speed trains at the time of the quake were also injured, said operators, who immediately suspended all services after the jolt.
Public attention was focused on the collapse of the Aeon mall, the largest in the prefecture.
One side of the mall, which houses around 200 stores, was torn away, exposing steel beams and strewing debris across a carpark, footage showed.
Some major companies with plants in the area, including Renesas Electronic, Sony, Tokyo Electron and Honda, have suspended operations at their plants.
Toyota Motor also said it would suspend work at three factories outside Kumamoto prefecture through Friday in consideration of the situation at suppliers.
TSMC, the world’s largest contract chipmaker, evacuated workers from its local plant as a precaution after the quake but said it had begun resuming operations late on Tuesday.
Located on the “Ring of Fire” of volcanoes and oceanic trenches partly encircling the Pacific Basin, Japan accounts for about 20pc of the world’s earthquakes of magnitude 6.0 or more.
A massive earthquake in Kumamoto 10 years ago killed 275 people and injured a further 2,739, according to an official count, and damaged thousands of buildings including the walls of the city’s castle, a top tourist site.
The castle was also among several historic buildings damaged in Tuesday’s quakes alongside shrines with heavy tiled roofs that partially collapsed and a 17th-century tea house.
