Group: Summary
  These data are intended for geographic display and analysis at the
  national level, and for large regional areas.  The data should be
  displayed and analyzed at scales appropriate for 1:2,000,000-scale data.
  No responsibility is assumed by the National Atlas of the United States
  or the U.S. Geological Survey in the use of these data.  This map layer is
  intended for a mixed audience of specialists and non-specialists alike who
  have a need for general, non-technical information about significant
  United States earthquakes.
  
  
  This map layer contains the locations and attributes of significant,
  historic earthquakes that caused deaths, property damage, and geological
  effects, or were otherwise experienced by populations in the United
  States, Puerto Rico, and U.S. Virgin Islands.  Included are earthquakes
  located in the United States as well as some that occurred in adjacent
  portions of Canada and Mexico.  The main sources for the data are
  Seismicity of the United States, 1568-1989 and the Preliminary
  Determination of Epicenters for 1990 to January 2004.  This is a
  replacement for the June 1999 map layer.
  
  
  Provided with the downloadable files is a text file,
  quksigx_references.txt, which contains the reference information for
  earthquake magnitudes listed in the data.
