A volcano eruption in Indonesia on Saturday claimed the lives of at least 16 people. The eruption, which unleashed clouds of deadly gas, came only a day after villagers who fled from earlier eruptions had returned home. Among the dead are four high schoolers, who had been on a school trip to see the volcano, and a local journalist. Lava and pyroclastic flows from Mount Sinaberg were sent surging down southern slopes up to 2.8 miles away. More than 30,000 people have been evacuated from the area.
