A 7.1 magnitude earthquake shook Japan’s southern main island of Kyushu on Tuesday, leaving several people dead and dozens of others injured or missing after part of a shopping centre and a huge chimney at a paper factory collapsed, officials said.  At least three people, including two who were found without vital signs at the mall late Tuesday, were confirmed dead, and about 30 others were injured across the Kagoshima prefecture, the Fire and Disaster Management Agency said. In Kashima Town, the quake collapsed the second floor of the AEON Mall shopping centre, trapping an unknown number of people there, according to the fire department in the prefectural capital of Kumamoto. Japan’s NHK national television said the collapse came after an explosion, believed to have been triggered by a gas leak at the building. Four people were pulled out with injuries and taken to a hospital, while 10 others were unaccounted for, the Kumamoto prefectural emergency response team said. It said the extent of the damage was still being investigated as the search and rescue effort continued. A 35-year-old male shopkeeper told Japan’s Asahi newspaper that he fled the building after the quake alert, and heard an explosion sounding like a bomb blast about an hour later. When he turned around, he saw enormous white smoke billowing from the mall. A female employee at the mall told Japanese broadcaster TBS television that she and her colleagues smelled gas when they returned to their shops after helping customers to evacuate out of the building, then heard the explosion. A man interviewed by Yomiuri newspaper said that his friend who works at the mall was missing, and he was praying for those who are unaccounted for to be safely rescued. At the Nippon Paper Industries Co.’s Yatsushiro factory, where a chimney collapsed and the building was damaged, 11 people were trapped underneath the debris, the Kumamoto emergency team said. Two of them were later found without vital signs, while the conditions of nine others were unknown, the team said.  The Fire and Disaster Management Agency said more than 260,000 people were advised to evacuate, most of them in Kumamoto prefecture, but also in the neighbouring Nagasaki prefecture. The affected area is about 900 kilometres (540 miles) southwest of Tokyo, the country’s capital. A tsunami advisory for the Ariake and Yatsushiro Seas on the western coasts of Kumamoto prefecture and three neighbouring prefectures was lifted within two hours, the Japan Meteorological Agency said.  Japan’s Prime Minister Sanae Takaichi told journalists that there were reports of damage to roads, bridges and buildings, as well as blackouts and fires, though details were unclear. The Fire and Disaster Management Agency said major public facilities or infrastructure were not damaged. Japan’s Nuclear Regulation Authority said no abnormalities were found at three nearby nuclear power plants. Kumamoto police have received more than 100 emergency calls following the quake, NHK said. Kyodo News said a hospital in the city of Yatsushiro took in about 40 people with injuries and about 50 others were taken to a hospital in Kumamoto city. The quake also affected a number of major manufacturers in Kyushu.
