Dust in the Cockpit: Volcanic Ash Aviation Hazards - The 50-Year Effort to Mitigate Them
The 1980 Mount St. Helens eruption was a watershed moment in our understanding of volcanic eruptions and their hazards. Among the lesser-known events during that summer was the first documented case of in-flight engine damage from volcanic ash on May 25,1980. Two years later, a 747 nearly crashed in Indonesia when it flew into an ash cloud from Galunggung Volcano and lost power to all four engines. A similar event in December, 1989 at Redoubt Volcano, Alaska finally convinced meteorologists, air traffic regulators, and volcanologists that we need a global infrastructure to detect volcanic ash clouds and communicate their trajectory to aviators.
