KARO, Indonesia – For the second time in as many days, a volcano erupted on Sumatra on Tuesday (September 17th), sending a 3km-high column of smoke and ash into the sky and forcing thousands more people to evacuate, AFP reported.

Witnesses said the mid-day eruption could be heard for miles and sent a huge black cloud billowing over Mount Sinabung.

White volcanic ash blanketed surrounding villages. An estimated 3,000 more people fled their homes Tuesday, after nearly 6,500 evacuated Sunday following the first eruption.
