  <dc:description>&lt;p&gt;The U.S. Geological Survey (USGS) began operating a network of seismograph stations in Yellowstone Park in 1964. The stations were self-contained and their locations were limited by the necessity for year-round access, 110-volt power, and a light-tight recording area. The network had a maximum of 5 permanent stations and was supplemented for 60 days in 1965 with up to 5 portable, battery-powered seismograph stations. Epicenters of earthquakes located with this network were published in Eaton et al. (1975).&lt;/p&gt;</dc:description>
