  ABOUT THIS DATABASE
  
  This database provides an overview of the studies being 
  conducted by the Long Valley Observatory in eastern 
  California from 1975 to 2001.  The database includes 
  geologic , monitoring and topographic datasets related to 
  Long Valley caldera.  The CD-R contains a scan of the 
  original geologic map of the Long Valley region by R. 
  Bailey. Real-time data of the current activity of the 
  caldera (including earthquakes, ground deformation and the 
  release of volcanic gas), information about volcanic 
  hazards and the USGS response plan are available online at 
  the Long Valley observatory web page 
  (http://lvo.wr.usgs.gov).   If you have any comments or 
  questions about this database, please contact the Scientist 
  in Charge of the Long Valley observatory.
