Transcript

pyroclastic density current entered Casa di Stabianus through openings and the collapsed roof.
Pompeii stood about 6 miles (10 kilometers) from Vesuvius's volcanic vent.
The main explosive phase began around noon on October 24th;
the eruption column reached 82,000 feet (25 kilometers).
Pumice and ash piled up to 10 feet (3 meters) deep, collapsing several house roofs.
Through the haze, the room seemed to tighten around the waiting figures.
Pompeii was buried first under pumice lapilli and later under ash from pyroclastic currents.
The second phase moved through Pompeii as a ground-hugging current.
The collapsed roof exposed the room beneath broken, suspended tiles.
Inside that house, researchers labeled the deposit EU4, about 9 inches (0.23 meters) thick.
The current killed people who had not escaped Pompeii.
Evidence points to a current with low strength, low temperature, and low pressure.
The casts show intact bodies without clear traumatic signs, while clothing survived unburned.
In the dim room, the last light faded from the walls.
At Pompeii, the pyroclastic current lasted 17 minutes.
That duration made breathing ash suspended in the current lethal.
At the house, the route out had become a route for the current in.

Yet the current’s deadliest weapon may not have been impact or burning—it was the ash people had to breathe for 17 minutes.
