Episode Details

Volcanic ballistics, hyperacidic lakes, and the breakdown of emergency communications, time to put Hollywood's geology to the test. We break down the science behind the 1997 disaster film Dante's Peak, sorting genuine volcanic precursors from cinematic flare.

Dr. Glyn Williams-Jones and the Physical Volcanology group at Simon Fraser University join the show for a watch party. They react to the film's chaotic progression, sharing personal field stories, while explaining how science teams manage life-or-death risks.
