In 1991 the dome of the Unzen Volcano in Japan collapsed. This video captures the pyroclastic flow. The running guy's scream is more chilling than the Wilhelm scream.
A pyroclastic flow is a fast-moving current of hot gas and rock (collectively known as tephra), which reaches speeds moving away from a volcano of up to 700 km/h (450 mph). The gas can reach temperatures of about 1,000 °C (1,830 °F). Pyroclastic flows normally hug the ground and travel downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. They are a common and devastating result of certain explosive volcanic eruptions.
Birgit Schlosser specializes in spare, clean architecture photography, and that aesthetic is also in play in Volcanic Dreamscapes, a new series of works depicting the beauty of sparse volcanic ecosystems.
