Powerful magnitude 7.7 earthquake kills at least 47 in Indonesia

At least 47 people have been killed after a magnitude 7.7 earthquake struck Indonesia early on Saturday, the nation's disaster mitigation agency has said. The official death toll has been rising as a search and rescue operation gets under way. The National Disaster Management Agency (BNPB) said several people had been injured to varying degrees. Hundreds of buildings in the region have been damaged by the quake and the dozens of aftershocks that followed. The quake struck the island of Flores shortly before 05:00 local time on Saturday (22:00 GMT on Friday). It had a depth of 15km, Indonesia's meteorology and geophysics agency stated. The shallower an earthquake is, the more destructive its effects on the surface tend to be. Aftershocks included a magnitude 6.4 earthquake in North Sumatra, located in western Indonesia, at a depth of 163km, BNPB announced. The US Geological Survey measured it at magnitude 6.9. Video taken at the port in Maumere showed large chunks of concrete breaking off the terminal building onto passengers waiting to board an inter-island ferry. Some were thrown into the sea when the gangway to a ship collapsed. Emanuel Melkiades Laka Lena, governor of East Nusa
