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.

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 molten rock is inside the earth, it’s called magma, but as soon as it erupts from a volcanic vent, it becomes lava. Lavas like basalt can flow like a red-hot river, while dacite and rhyolite lavas can ooze slowly out of the volcano to form a lava dome. Some lavas can flow faster than a person can run, but normally lava travels slowly enough for people to move out of its way. Everything in the path of an advancing flow can be knocked over, surrounded, burned or buried. Scientists are able to

Pyroclastic flows (referred to more often today, as pyroclastic density currents) are rapidly moving avalanches of hot rock, dust and gas that flow down the sides of a volcano. What makes them especially devastating is that they are extremely hot and can travel for several miles from a volcano. They can form during an eruption when hot pulverized rock and gas that first rapidly rises into the sky falls back, forming pyroclastic flows that race down the sides of the volcano. Other times, pyroclas
