Mayon volcano forces flight cancellations as pyroclastic flows reach 4 km and SO2 hits 2,098 tonnes per day
Pyroclastic flows from Mayon Volcano surged 4 kilometers down the Mi-isi Gully in late May 2026, marking the farthest runout since the current eruptive episode began. Sulfur dioxide emissions spiked ...
Avalanches of ash, gas and rock that cascade downhill during volcanic eruptions may be even more dangerous than scientists had realized. Pulses of high pressure form within these slides, known as ...
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 ...
