Simultaneous eruptions at 5 volcanoes in Indonesia shrouded the skies with ash.
Three airports closed and thousands have been evacuated.
Mount Raung on Java island blasted ash and debris up to about 6,560 feet into the air after rumbling for several weeks.
Ash erupted also from Gamalama and Dukono mountains on the Moluccas islands chain, Sinabung volcano on Sumatra island and Mount Karangetang on Siau island, darkening the skies.
Here a video of Mount Raung volcano on July 10, 2015:
Jember and Banyuwangi airports closed late Tuesday and Bali’s international airport was closed for several hours on Wednesday, disrupting flights.
A total of more than 13,000 people have been evacuated due to the volcanic eruptions since last month, mostly from around the slopes of Sinabung in Tanah Karo District.
According to scientists, there is no extraordinary natural phenomenon behind the five simultaneous eruptions. All are natural and normal occurrences in a nation with about 130 active volcanoes. Yes of course!
