Dozens of flights to and from Indonesia’s Bali island were cancelled Monday after a volcano belched a colossal ash tower 18 kilometers (11 miles) into the sky, authorities said. The aviation disruption came just weeks after the same rumbling volcano caused dozens of flight cancellations to and from the popular resort island.

Indonesia's rumbling Mount Lewotobi Laki Laki has erupted with a column of volcanic materials as high as 11 miles into the sky, ash falling on villages and several flights have been cancelled.

The ash cloud above Mount Lewotobi Laki-laki on Monday was about four times taller than the one produced by an eruption there last month.
