In this activity, the process of finding the epicenter of an earthquake with a travel time graph is simulated. During the course of this activity students will model how earthquake waves travel through the Earth at different speeds, construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel time-curve), and use the constructed time-travel graphs to locate the epicenter of a simulated earthquake by triangulation. The site contains detailed instructions and all of the charts and graphs required. Sample data is also included.
