(REUTERS)A powerful 7.1-magnitude earthquake that struck southern Japan on Tuesday triggered a second disaster when a shopping mall partially collapsed in a suspected gas explosion about an hour later, killing at least 13 people and leaving several others missing as rescuers raced against time to search for survivors. Eight people were pulled from the rubble of the partially collapsed Aeon shopping mall near Kumamoto, but three later died, news agency Reuters reported. Mall operator Aeon said four employees remained unaccounted for after checks of its roughly 2,700 staff, while seven more people were missing after a chimney collapsed at a Nippon Paper Industries factory. Authorities said hospitals were treating dozens of injured people across the region.
