An array of ten triaxial strong-motion stations has been installed on the surface above two underground longwall coal mines in western Colorado (USA). The district-scale network monitors mining-related and natural seismicity throughout an area of approximately 250 square kilometers of rugged canyon-mesa terrain. The real-time automated seismic event monitoring and notification tool features: password-protected Internet access to raw and processed data, web-client software that provides real-time graphical display of event locations, and email and paging notification of high acceleration levels and large magnitude events. This paper describes the network installation and the methods used to collect, process, and distribute seismicity information to its users and gives several examples of the collected data.
