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.
