This paper discusses the design, installation, and performance of a remote microseismic monitoring system in a mountainous terrain. The system was designed to detect local seismic events that could be precursors of a landslide or indicators of seismic activity related to hydrocarbon production in the area. Six 3-component seismic stations were installed on Turtle Mtn., Alberta, Canada - site of North America's most fatal landslide in 1903. The area is also host to considerable natural gas production. We discuss the sensors used, recording apparatus, data transmission, marshalling, and storage. Event detection algorithms have been developed and hypocentre determination codes emplaced. We provide an overview of recent results.
