Excerpt: ... digital seismographs will likely be the most useful instrument for CUS RAMP deployments because they can be rapidly deployed and provide digital records for subsequent data analysis and interpretation. The short-period digital seismographs are mostly multichannel instruments that have the advantage of providing 3-component seismic data that can be used to analyze and interpret all seismic phases. Furthermore, a large number ( ten, initially from IRIS / PASSCAL; additional from both IRIS / PASSCAL and University and government sources ) of reasonably matched, digital seismographs are available on short notice for RAMP deployments. Broadband digital seismographs can be used for a CUS RAMP deployment and could provide scientifically interesting data. However, effective deployment of broadband seismometers is more complicated and takes more time than short-period seismometer deployment. Furthermore, broadband seismometers deployed in the relatively unconsolidated surficial materials that characterize much of the seismically active CUS may be unstable. The number of seismographs used in a CUS RAMP deployment will depend on a number of factors including: the magnitude and effects of the event that triggers the deployment, scientific and mitigation objectives, and the availability of funding, field personnel and instruments. Initial deployments will most likely use locally available analog and digital seismographs and perhaps the IRIS / PASSCAL RAMP instruments. If an extensive deployment is planned, additional seismographs ( probably including some broadband instruments ) will be available on relatively short notice ( 1-3 days ) from IRIS / PASSCAL and university and government laboratories. Because permanent networks of seismographs exist in the CUS, design and operation of a temporary...
