Mount Raung Volcano have been very active during July 2015, with almost continious activity. Ash emissions have shut down airspace for commercial flights, forcing planes to reroute and several airports to close for several days. The airports that have been affected are Bali International airport, Surabaya International Airport, Jember airport and Banjuwangi airport. The airports have closed on the days where ash-emissions have affected these areas.
These photos was taken on the 2th August 2015, from the Tengger Caldera, approximatly 120 km west of Raung. Ash was seen drifting in a southern direction of the volcano. Activity seemed to have increased, compared to observations made on the 28th July and 1th August 2015.
