Mount Agung volcano eruption: Mount Agung has been hurling clouds of white and dark gray ash about 3,000 meters (9,800 feet) into the atmosphere since the weekend and lava is welling up in the crater, sometimes reflected as a reddish-yellow glow in the ash plumes. Its explosions can be heard about 12 kilometers (7 1/2 miles) away. Indonesian authorities ordered a mass evacuation of people from an expanded danger zone around an erupting volcano on Bali that has forced the island's international airport to close, stranding tens of thousands of travelers. Volcanic ash poses a deadly threat to aircraft, and ash from Agung is moving south-southwest toward the airport. Ash has reached a height of about 30,000 feet as it drifts across the island.
