This web site provides an interactive map of global seismic activity that is updated every 30 minutes. The site uses data from the National Earthquake Information Center to produce a world map with clickable areas of seismic activity. Users can click on geographical areas of the map, and will be taken to a table which describes the time, location, magnitude and comments about particular seismic events. Information is kept for earthquakes that have occurred in the last 24 hours, 15 days, and five years. For earthquakes of a magnitude of 6.0 and over, links are provided to special information pages that try to explain the where, how and why that particular event occurred. The user can also view the ground motion associated with an event and visit seismology laboratories around the world.
