Cathryn,
My computer skills are somewhat behind the times. I am unable to sent the URL in a message. At the bottom of the USGS map and three boxes with blue headings. The one on the right says Information. There are several listings in the box and the last one is About Real Time Earthquake Maps.Click on that one and then onthelistings for Glossary.
