Thus, a distributed digital network reduces the detection threshold more than might be assumed from just an increase in the station density. To test whether the increased network sensitivity is indeed an artifact of the greater density of digital stations in southern Nevada, we also compared the analysts' catalogs north of 38 N, where there are fewer digital stations. CUSP processing produced 37 events versus 107 for Antelope . This still implies a tripling of analysis effort. We were not prepared for the increase in workload attending this increase in network performance.
Sensors are of comparable quality and response.
Clearly the integrated network is providing a more complete view of seismicity in western Nevada. It is reasonable to expect improved estimates of fault activity, perhaps identification of new faults, and a better sense for interseismic processes. We now have real-time displays for data viewing, quality control, and communications confirmation. The system is approachable by every person in the lab, from the technicians to the director. Because the digital stations stay on scale, local magnitude Ml can be estimated where only duration magnitude Md was previously available.
