Recent Eqs Map Legend
The sizes of symbols scale with earthquake magnitude, and their color with either the age of the earthquake or its depth, as shown in the legend below, and selected in the panel to the right of the map. Clicking on an earthquake symbol shows its basic details and a link to a page with more details about the individual earthquake. Probable surface explosions (usually due to quarrying or road building) are shown as stars.
The U.S. Department of Energy is building a field laboratory to develop the technologies needed to make commercial EGS (Enhanced Geothermal Systems) a reality. The project, known as FORGE (Frontier Observatory for Research in Geothermal Energy), is located near Milford Utah. UUSS is responsible for monitoring background seismicity and potential seismicity related to operations. Currently, a five-station seismic network has been installed in close proximity to the site that is capable of reliably detecting and locating earthquakes down to magnitude zero. Borehole seismometers will be added as the facility develops. All raw waveform data can be viewed through webicorders available on this site, and can be downloaded through the IRIS DMC. Archived event locations can be downloaded using the search tool below and through the USGS Comcat.
