On Wednesday the Indonesian government opened an airport on Bali as wind blew away ash spewing out of a volcano, clearing the air for planes and giving residents and tourists a chance to escape.

In the past several days, the volcano has disrupted operations at Bali's airport, the second-busiest in Indonesia, while tens of thousands of residents living within a 10-kilometer radius of Mount Agung have been told to leave. Around 43,000 people had fled, but an estimated 90,000 to 100,000 people were still living in the eruption zone.
