(All real-time  data exchange is via Earthworm Import/Export unless otherwise noted)

All realtime waveform data (220 stations, 454 channels) are sent to IRIS Data Management Center via tape after QC

We have processed an average of 476 events per month over the past two years. An average of 90 of these are from outside the region (teleseisms, etc).

Our recording and processing system consists of three SUN computers runing earthworm software in overlapping redundant mode in the lab. There are two other local computers only digitizing (NT-earthworm and SUN-sunworm).  There are three remote nodes (1 SUN, 2-NT) for local data acquisition and forwarding to UW via Internet (total of 45 channels).  The cooperating networks (UO, HW) have a combination of NT-earthworm digitizers and SUN-earthworm processing computers and forward a total of 28 channels via Internet.
