TOKYO — Rescuers were frantically searching on Wednesday for survivors of a powerful earthquake that shook southern Japan, killing at least 13 people, knocking out power to thousands of homes and rupturing roads across the region.The earthquake struck Tuesday afternoon with a magnitude of 7.1, according to the Japan Meteorological Agency. The US Geological Survey measured it at magnitude 6.8.Rescuers were sifting through the rubble in the key sites including the Aeon Mall in Kashima town and the Nippon Paper factory in Yatsushiro, in what Prime Minister Sanae Takaichi described as a “race against time”The quake registered a maximum 7 on the Japanese shindo intensity scale when it struck Kumamoto prefecture on the southern island of Kyushu. The government has said more than 9,000 people were in evacuation centres across the country early Wednesday.“We have received reports of seven people with serious injuries and 29 with minor injuries. Furthermore, as of 7:00 am today (2200 GMT Tuesday), 9,186 people have sought refuge in 506 evacuation centres across five prefectures, including Kumamoto and Fukuoka,” government spokesman Minoru Kihara said a day after the quake.Eight people were pulled alive from the rubble of a partially collapsed shopping mall near the city of Kumamoto that was torn apart by an apparent explosion about an hour after Tuesday’s earthquake. Two women in their 20s were confirmed dead in the explosion, and another person reportedly suffered cardiac arrest.Around 20 to 30 mall workers were unaccounted for on Tuesday, public broadcaster NHK said.“Even now, there are people waiting to be rescued, and this is a race against time. We will marshal all available resources on the ground to save and rescue as many people as possible,” Takaichi told reporters in Tokyo.Authorities are investigating a possible gas explosion at the Aeon mall, media reported. Rescuers reported smelling gas inside the building but the cause of the incident was still under investigation, Japan’s top government spokesperson Minoru Kihara said.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.Seven people are also missing after a chimney collapsed at a Nippon Paper Industries factory, while four others are seriously injured, a local government official said. Hospitals were reported to be treating dozens of patients.Across the prefecture, which also suffered a deadly earthquake a decade ago, around 260,000 people were instructed to go to evacuation centers, 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 epicenter was about 20 kilometers south of Kumamoto City, central Kyushu’s largest city with a population of around 700,000.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. With more than 36,000 homes still without power as temperatures soar to around 34°Celsius on Wednesday, authorities also warned about the risk of heat stroke.One hospital in Uki city, near the epicenter, 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 parking lot, footage showed.A spokesperson for mall operator Aeon said customers and employees were evacuated right after the initial quake and that the exact cause of the ensuing explosion was unclear.Some major companies with plants in the area including Sony, Tokyo Electron and Honda said they would suspend operations at their plants through Wednesday.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.Some roads were also badly damaged, with large cracks splintering major highways and snarling traffic on Tuesday evening.Located on the “Ring of Fire” of volcanoes and oceanic trenches partly encircling the Pacific Basin, Japan accounts for about 20 percent 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.TOKYO — Rescuers were frantically searching on Wednesday for survivors of a powerful earthquake that shook southern Japan, killing at least 13 people, knocking out power to thousands of homes and rupturing roads across the region.The earthquake struck Tuesday afternoon with a magnitude of 7.1, according to the Japan Meteorological Agency.
