Abstract

Pyroclastic flows that emerge from the bases of collapsing eruption columns or lava domes are transient dynamic phenomena, rarely documented due to their very brief existence, which may be only minutes. Such flows are commonly reconstructed from their deposits. They have been photographed on the ground, but to the best of our knowledge, the pyroclastic flow described in this article is the first such flow in action that has been recorded on a satellite image. This provides an excellent opportunity to see the flow in action.
