Earthquake Wave Travel Time Concepts

The video tutorial explains how to calculate the difference in arrival times between P and S waves from an earthquake at a distance of 5,600 kilometers from Albany, New York. It uses a travel time chart to determine that the P wave takes 9 minutes and the S wave takes 16 minutes and 10 seconds to travel this distance. The tutorial concludes that the S wave arrives 7 minutes and 10 seconds after the P wave. This knowledge is essential for the earth science lab practical and the Region's exam.
