Lectures and previous brief assignments dealt with plate tectonics, earthquakes, volcanoes and tsunamis. For the assignment, students read several articles describing potential sources for tsunamis on the east coast, including volcanic eruptions on the Canary Islands, underwater landslides off the shelf, and earthquakes. Their task is to summarize these potential sources, evaluate the risk of a tsunami on the east coast, and compare them with previously discussed risks for the west coast and Hawaii.
