Controversies in the Earth Sciences

Summary and Final Tasks

Tsunami Evacuation Route graphic (1 km.)

In this lesson, you studied the catastrophic effects of a tsunamigenic earthquake and evaluated the potential risks posed by tsunamis in other parts of the world. One of the obstacles faced by those who make a living trying to assess risk and mitigate the hazards posed by geologic activity is that the timescale in between potential disasters in a specific location (e.g., large earthquakes or volcanic eruptions) is often too long for humans to have accurate statistical measurements of how often it might happen. This makes reconciling the cost of preparedness with scientific accuracy a little tricky. In the next lesson, we'll study this problem in a place that is potentially hazardous for earthquakes.
