Hawaii’s Mauna Loa, the world’s largest active volcano, has erupted for the first time in nearly four decades, causing volcanic ash and debris to fall nearby, authorities say.
Flows of lava remained contained within the summit caldera of Mauna Loa in the US island state, but the eruption could pose a threat to nearby residents should conditions change, the United States Geological Survey reported at 11:45 pm Sunday (09:45 GMT Monday), about 15 minutes after the eruption in Hawaii Volcanoes National Park .
