Spectacular Pyroclastic Flow From Indonesian Volcano Caught On Camera

July 2015 has been an explosive month for Indonesia. Eruptions of ash at five volcanoes shrouded the skies over parts of the Indonesian archipelago on Wednesday, forcing three airports to close. 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 government volcanologist Surono.

Volcanic activity is usually a unique and beautiful sight which few people will see in their lifetime, but this incredible footage allows you to see it close up from the safety of your screen.

Early on 3 July 2015, a rare and spectacular pyroclastic flow occurred at Batu Tara volcano that traveled approx. 150m over the sea. It was caused by the collapse of the eruption column and accumulated loose material on the crater rim, following a strong, mass-rich explosion from the volcano.
