Pyroclastic flows in Whites Ghaut in daylight (28 - 31 Jan 2010)
A big pyroclastic flow in White's Ghaut covers the entire dome.
A spectacular column of billowing ash dwarfs the trees in foreground.
The column from the last flow rises above earlier ones.
The impressive flow front: dead trees at bottom right give the scale.
The two-hundred-meter wide pyroclastic flow quickly advances towards us.
Meanwhile, billowing ash hides the entire White's Ghaut.

The dead trees at bottom left were burnt by a previous flow already.
The flow stops and a strong wind suddenly depresses its front.
Billowing ash continues to rise from the entire pyroclastic flow.

As it stops, the strong wind drags billowing ash to the west.
