The EQTrace Earthquake Atlas is an interactive web app that displays selected earthquake events from the publicly-available United States Geological Survey (USGS) on-line repository. You enter search criteria, optionally including a designated geographic area, and the events are presented on a 3-dimensional globe or a 2-dimensional map. EQTrace provides both a static display and a simulation capability; the simulator displays the selected events in time order.
The data source is the USGS Earthquake Catalog portal, which provides access to all Earthquakes maintained in the USGS database, dating from January, 1900 to the present.
