"We Need All the Assistance You Have..."
This exercise provides a basic introduction to volcanic hazards. Students learn about different types of volcanic hazards through researching examples from Alaskan eruptions. They also group the hazards as proximal and distal to consider how emergency response plans might differ. A recording of the KLM flight 867 flight that lost power to all four engines when it flew into an ash cloud from a 1989 Mt Redoubt eruption provides a compelling example of risk from volcanoes. (Note: the plane was ultimately able to regain enough power to land safely in Anchorage.) Students learn about the Volcano Hazards Alert-Notification System for both ground-based and aviation applications.

- Flight Recording from KLM 867 as it flew into an ash cloud in 1989 (PowerPoint 999kB May27 18) - This short recording provides a vivid example of the dangers volcanic ash clouds pose for aircraft. (Note: the flight ultimately made an safe emergency landing)
- Supporting Presention: Alaska Volcanoes Guidebook for Teachers (Acrobat (PDF) 9.3MB May27 18) - These slides are intended to support the entire Alaska Volcanoes Guidebook for Teachers. Elements of the presentation could be delivered by the instructor or it could be given to the students as an information source for their research on Alaskan eruptions and volcanic hazards.
