About 60 million cubic meters of dome and crater wall traveled to the south as a debris avalanche and pyroclastic density currents.
On 25 June 1997, pyroclastic flows from an eruption resulted in the first deaths directly caused by the volcano.
Topics covered include: lava flows, pyroclastic flows, flank collapse, landslides, and lahar deposits.
Tuff A type of pyroclastic rock which is derived from the collapse of volcanic ash clouds.
They had either gone out to check a nearby pyroclastic fall deposit or had spent the night asleep on the beach !
Pyroclastic fragmental volcanic material that has been blown into the atmosphere by an explosive eruption.
Two of the trips to the PÃ¡ramo ended in pyroclastic events.
His Ph.D. focused on the processes involved in the deposition of subaqueous pyroclastic flows and was supervised by Steve Sparks.
To survey the main building types in the areas principally at risk and to assess their vulnerability to pyroclastic flow and tephra fall damage.
