### Network Characteristics:

Pacific Northwest National Laboratory helps maintain the eastern Washington portion of the Pacific Northwest Seismograph Network, a set of about 30 analog short-period stations with radio and microwave telemetry. These stations along with several local stations in the Pasco Basin are recorded at PNNL as part of its environmental monitoring of the Hanford region.

Standard EarthWorm Modules in current Use:

PNL is installing an earthworm system on a Pentium 200 MHz MME processor running Windows NT. The system includes two external fast-wide scsi disks in addition to the standard EIDE internal drive (2x4 Gb Seagate Barracuda, on Adaptec 2940 controller), 3Com 3C905 10/100 Mb/s network interface, National Instruments PCIMIO16E4 12-bit A/D converter with AMUX64T multiplexer. We immediately plan to use the PC and earthworm software to monitor approximately 40 analog-telemetry stations from the eastern Washington region. Future integration of additional broad-band and strong motion instruments is expected, as are automatic notification functions. Analysis, reporting, and data archival will be conducted by analysts using UNIX workstations and UW analsis software.

- startstop, copystatus, diskmgr, statmgr control and status
- <adsend digitize analog data on NT
- pick_ew, binder P-picking and associations
- eqproc, eq_prelim, eqcoda, eqverify filter & quality check
- <hypomgr, hypoinv, eq_alarm produce locations and notify

### Associated programs/modules being developed or adapted here:

- carl_trig (Detect station triggers and network events)
- fftrace_save (Use some sort of trace saver when available)
