The bodies of 11 climbers were recovered Monday a day after a furious eruption of the Mount Marapi volcano as Indonesian rescuers searched for 12 apparently still missing.

Marapi has stayed at the third highest of four alert levels since 2011, a level indicating above-normal volcanic activity and prohibiting climbers or villagers within 3 km of the peak, said Hendra Gunawan, the head of the Center for Volcanology and Geological Disaster Mitigation.
