In view above and below is a series of maps showing the earthquakes in 1997 across the world and around North America. The animated GIF will cycle through each image for five seconds, then repeat endlessly. Below, each image can be seen separately.
Interesting patterns are visible by studying the images.
The data presented here were drawn from the USGS NEIC's searchable databases located on the World Wide Web. You can also create maps of even more recent quakes by going to a live online mapping site. The earthquake data represented here are also available on the CD, for you to explore using ArcVoyager Special Edition or ArcExplorer .
