Summary

Students act as first responders assessing Lahar risks associated with eruptions. Teacher sets an alert placemark on the Google Earth web browser plug-in and gives students X minutes to decide whether to evacuate a down-slope town. Students collaborate by text messages.

Learning Goals

Students learn to analyze a risk map, read the terrain slope, and collaborate in decision-making.

Methods of Geoscience

Slope analysis, Superposition, Map Interpretation

Context for Use

This activity was first designed for a Geology for Civil Engineers course but also worked well in freshman Natural Disasters and could be easily adapted to many other settings. Students and teachers need only to be able to use Google Earth and a web browser.
