The Indonesian authorities closed four airports on Friday, July 10, including one in Bali, due to volcanic eruptions from Mount Raung. The volcano is one of the most active on the island of Java and began to erupt again around a week ago. Flights were cancelled between Bali and Australia earlier this week because of an ash cloud blowing near Denpasar Airport.
