The locations of significant earthquakes in the United States, Puerto Rico, the Virgin Islands of the United States, and in adjacent portions of Canada and Mexico from 1568 to 2004.
The National Earthquake Information Center (NEIC) manages, disseminates, and archives earthquake information. The NEIC is part of the Earthquake Hazards Program at the U.S. Geological Survey (USGS). The NEIC focuses its efforts on mitigating the risks of earthquakes to mankind. Toward this goal, the NEIC works to determine the location and size of all destructive earthquakes, pursues an active earthquake research program, and collects and provides an extensive earthquake database that serves as a solid foundation for scientific research to scientists and to the public. This map layer was produced by the Geology Discipline of the USGS using data derived from the online earthquake database maintained by the NEIC.
The Significant United States Earthquakes 1568 - 2004 map layer shows the location of earthquakes in the United States, Puerto Rico, the Virgin Islands of the United States, and in adjacent portions of Canada and Mexico from 1568 to 2004. Significant earthquakes are defined as those that caused deaths, property damage, or geological effects, or that were experienced by populations in the epicentral area. Detailed descriptive information about each earthquake is provided including the date and time of occurrence, the location in both geographic coordinates and narrative form, and the magnitude according to several different measures. Additional earthquake information can be found on the USGS Earthquake Hazards Program home page and the Earthquake Hazards Program Maps page.
