PYROCLASTIC FLOW A pyroclastic flow is a fast-moving current of extremely hot gas, volcanic ash, and rock fragments that rushes down the slopes of a volcano during explosive eruptions. These flows can reach speeds of over 320 km/h and temperatures exceeding 1,000 °C, making them one of the most dangerous volcanic hazards. Unlike lava flows, pyroclastic flows can travel great distances, destroy everything in their path, and cause widespread devastation due to their speed, heat, and suffocating as

When a volcano erupts, pyroclastic flows are often the biggest danger to anyone nearby. These fast-flowing currents of rock, ash and hot gas are extremely difficult to study, so researchers created their own.

Gas samples from Mt. Vesuvius can reveal how close magma is to the volcano's surface. To collect them, researchers descend into Vesuvius' 1,000-foot-deep crater. "The Next Pompeii" premieres on Wednesday, February 20 at 9/8c on @PBS: https://to.pbs.org/2sQQR1z | NOVA l PBS

The eruption of Vesuvius devastated Pompeii and Herculaneum, but in dramatically different ways. As ash and pumice billowed from the eruption site, prevailing winds pushed it south, smothering Pompeii. Meanwhile, a mixture of superheated steam, ash, mud, and rock sped down the west side of the mountain at up to 450 miles per hour. This pyroclastic flow devastated Herculaneum. Learn more about this dramatic eruption and its aftermath in The Roman Empire: From Augustus to the Fall of Rome. https:/
