Pyroclastic Flow Hazard Map

Lahar and flood hazard map. Erupting volcanoes can pose many hazards, including volcanic ash, lava flows, pyroclastic flows and lahars. The basal part of the pyroclastic flow was confined to the channel bottom, but the overriding hot ash cloud burned and killed vegetation along the channel.

These maps typically display two zones threatened by pdc hazard: This is the key difference between eruptions and the other principal natural hazards like floods and earthquakes. The pyroclastic flow inundation extents between the two different methods agree at about 86%, suggesting the capability of mapping pyroclastic flow inundation by combing radar and optical imagery as well as flow modeling.

Comparison of the extent of the pyroclastic flow deposits of february 11, 2010 (a) and a computer simulation (titan2d model with 20 mm 3 collapsing to the north) of.

These currents can be dilute, as in pyroclastic surges, or concentrated, as in pyroclastic flows. Analyze data from a computer. These maps typically display two zones threatened by pdc hazard: Pinatubo volcano hazard map of zambales.
