Mount Raung on the main island of Java blasted ash and debris up to 2,000 meters (6,560 feet) into the air after rumbling for several weeks, and Gamalama mountain in eastern Indonesia erupted Thursday morning after months of quiet.
Transport Ministry spokesman Julius Adravida Barata said volcanic ash spewing from Raung blew close to the cities of Surabaya and Malang, forcing Juanda International and Abdurrahman Saleh airports to close.
