For the second day in a row, one of Indonesia’s most active volcanoes, Mount Lewotobi Laki-Laki, erupted. 

The explosion launched a column of smoke and volcanic material shot up to 11 miles in the sky early Saturday morning. Debris from the volcano blanketed villages, but no casualties have been reported. The explosion was one of the country’s largest since the 2010 eruption of Mount Merapi, the country’s most volatile volcano.

On Friday, in an eruption that occurred just hours before the one Saturday morning, smoke and ash went as high as 6.2 miles, as the volcano lit up the sky with glowing lava and bolts of lightning.

The explosion comes less than a month after Bali’s Ngurah Rai Airport was forced to delay and cancel flights when a major eruption on July 7 covered the roads and fields with debris. 

Indonesia is home to 280 million people and has 120 active volcanoes. It sits along the “Ring of Fire,” a horseshoe-shaped series of seismic fault lines encircling the Pacific Basin.
