The discovery of the driving force behind the world's deadliest volcanic events could help improve forecasting of their devastating effects, new research suggests. The findings reveal the mechanism ...
A superheated torrent of gas, rock, and volcanic debris tore 4 kilometers down Mayon volcano’s Mi-isi Gully in early June 2026, marking the longest pyroclastic density current recorded during the ...
A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ...
Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through large dynamic pressures of 100–102 kilopascal inside flows that are capable of obliterating ...
