Title: Great for classroom viewing
Review: This is a great video to demonstrate the impact of primary and secondary waves in the earth science classroom and provides students with perspective regarding how earthquakes contribute to studying the structure of rock layers.I'm not sure what video some of the other viewers watched, but I would give this video a high recommendation. Pictures from the actual event are blown up and presented by USGS scientists to demonstrate earthquake phenomenon. While I would agree that the production may be a little over dramatized at times it is important to remember that this event is still one of the United States biggest disasters that contributed to scientists understanding of plate tectonics on the west coast.
