The sweltering weather heightened worries about the survivors as rescuers braved the heat. The company said some 3,000 customers were evacuated to a car park before a gas explosion happened in another part of the shopping centre, where some people were still working. Three people remained missing, while four deaths were confirmed at the shopping centre site, according to Aeon. Japanese media footage of the shopping centre showed that part of a ceiling had caved in, and metal parts and other debris were scattered about as helmeted and masked rescue workers searched the area. Nearly 34,900 homes were still without electricity and some 15,000 homes were without running water, Kumamoto officials said.
