A group of scientists from Te Kunenga ki Pūrehuroa Massey University recently co-published an article on the hazard impacts of pyroclastic density currents. Pyroclastic density currents are ...

April 9 (UPI) --Large volcanic eruptions can trigger the formation of superheated gas-and-ash clouds. These pyroclastic density currents, or pyroclastic flows, are the most lethal volcanic threat.

Scientists have discovered that the scorching material spewed from a volcano during eruptions generates a layer of air between it and the ground, allowing it to surf along at extreme speeds, ...

Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through large dynamic pressures of 10 0-10 2 kilopascal inside flows that are capable of obliterating ...

When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards ...

After an eruption, DIY cushions of gas help searing torrents of gas, ash, and rock spread miles from their source within a matter of minutes. Pyroclastic flows contain a deadly combination of hot rock ...

The geologic hazards facility, though still millions of dollars and several years away, is already in the planning stages. I spoke last week with Greg Valentine, professor of geology and director of ...

Geologists have determined why — unlike in the neighbouring town of Pompeii — the inhabitants of the ancient Roman town of Herculaneum were not well-preserved by the eruption of the volcano Vesuvius ...

Car buried by volcanic debris during the 1980 eruption of Mount St. Helens. CVO/USGS. You can picture it: the heroes of our story are trapped near an erupting volcano. They need to escape, so they ...

The second factor, degree of orientation towards the summit, was more complex to create. I used the Pixel Location module to create two new images with the x and y UTM coordinate values stored. I ...
