To observe the movement of pyroclastic flow safely, the researchers recreated the currents inside a laboratory using materials from an actual volcanic eruption in New Zeland 2,000 years ago.

Dumping literal tons of hot volcanic material down a lab flume may finally have revealed how searing mixtures of hot gas and rock travel so far from volcanic eruptions. These pyroclastic flows can ...

Pyroclastic flows are a leading cause of eruption-related deaths. Now, lab tests reveal the mind-bending reason they may rush down a volcano’s flanks.

Pyroclastic flows contain a deadly combination of hot rock fragments and gas. Temperatures regularly top 1,000 degrees Fahrenheit, and these torrents can careen down mountainsides at hundreds of ...

Pressures within pyroclastic flows may be as much as three times as great as observations had suggested.

Volcanologist Professor Chris Jackson discovers evidence of the deadly pyroclastic flow.

Pyroclastic flows of the 18.8 Ma Peach Spring Tuff super-eruption travelled >170 km and entrained substrate blocks up to ∼1 m diameter. Here, the authors show that these flows had a dense ...

The Smithsonian’s Benjamin Andrews also uses lasers in his lab’s “tank” to study the behavior of pyroclastic flows.

ICYMI, back in 1991, a volcanologist literally outran a volcanic eruption - specifically a pyroclastic flow. If you haven't seen the video, then you've been missing out.
