Pyroclastic Flow followed by series of Tornados, Sinabung Volcano

See on Scoop.itLinks for Units of Inquiry in PYP

The pyroclastic flow deposits red-hot material on the slope of the volcano. After a few minutes, air heated by the deposit establishes a convective regime and due to the speed of the rising air a series of small tornados are formed.
During daylight it is difficult to imaging how hot the deposit is. Click here to see a pyroclastic flow deposit glowing at night from this same location.
