Indonesia shut a provincial airport and evacuated hundreds of people from the vicinity of the Ruang volcano after it belched explosive plumes of lava, rocks and ash for days, officials said on Thursday,

Indonesia’s Mount Ruang has erupted at least three times this week, forcing the evacuation of hundreds of people. On Wednesday evening local time, the volcano’s explosive eruption shot ash nearly 70,000 feet high, possibly spewing aerosols into the stratosphere, the atmosphere’s second layer.
