This map shows active seismometer networks in Colorado. Networks operated by different entities are shown with different colors. Seismometer networks are necessary to accurately measure location, magnitude, and intensity of seismic activity for research and public safety. You may notice that coverage in Colorado is sparse and unevenly distributed. CGS will be adding to the seismometer network beginning in summer of 2016.
