MEDAN, Indonesia—Indonesia’s rumbling Mount Sinabung erupted Monday, sending a column of volcanic materials as high as 5,000 meters (16,400 feet) into the sky and depositing ash on villages.
Falling grit and ash accumulated up to 5 centimeters (2 inches) in already abandoned villages on the volcano’s slopes, said Armen Putra, an official at the Sinabung monitoring post on Sumatra Island.
