Special Data Collection Systems (Project T/4703) January through Jun 1977

Abstract

Two SDCS systems which were deployed in early 1975 remained in operation at their original sites. These sites are at Houlton, Maine, and Red Lake, Ontario. The Houlton site uses a Model 36000 borehole seismometer system and the Red Lake Site uses standard SDCS (surface) instrumentation. Three SDCS systems remained in operation at the Nevada Test Site (NTS). These systems record short-period data only on both analog and digital recorders. The site at Oak Spring Butte was operational throughout the period. Two systems located in Pahute Mesa (NT-NV and NT2NV) were relocated to the Yucca Flat area of NTS in order to collect data in the immediate vicinity of known signal anomalies. Single short-period vertical component sites were also added as outriggers in order to complement data from each of the NTS systems. During May and June, three additional SDCS units were placed in operation at sites near the detonation points of events off the NTS. The sites are in remote areas and record short-period data on analog tape only. These units are to collect data to complement the NTS data being used in present magnitude anomaly studies. The sites are Faultless, Nevada (near the FAULTLESS event); Tatum Dome, Mississippi (near the SALMON event); and Gasbuggy, New Mexico (near the GASBUGGY event).
