Simulating how pyroclastic flows generate tsunami
Pyroclastic density currents are highly dangerous ground-hugging currents (flows) from volcanoes. The PELE facility (Pyroclastic flow Eruption Large-scale Experiment) at Massey University allows researchers to synthesize the natural behaviour of pyroclastic flows as they occur in nature…but safely and on a smaller scale.
Pyroclastic flows can displace enough water to generate a destructive tsunami, and this behaviour is a key focus for the Beneath the Waves research programme. The team have been modifying the PELE apparatus to extend the tsunami simulation chamber. This large scale equipment can replicate the shape and long duration of tsunami, revealing valuable secrets about the little-understood waves and coastal inundation.
The Resilience Challenge published this article, which explains the apparatus and showcases the world-leading experiment into pyroclastic flows.(external link)
