| This event report contains seismic data from the Special Data Collection System (SDCS), and other sources for the above event. Published epicenter information from seismic observations is presented. All SDCS stations were operational during this time period. HN-ME data were retrieved from analog back-up system due to bad memory unit in the digital system. Long-period at all SDCS stations was negative. Short-period horizontals were rotated. |

| Three Seismic Data Collection System (SDCS) stations were deployed at the Nevada Test Site (NTS) and two in the Eastern United States (EUS) to measure magnitude residuals and spectral differences between NTS and EUS stations. The deployment was intended to determine the degree of anelastic attnuation under NTS. At the Climax Stock (OB2NV) station, the teleseismic body-wave magnitudes are .17 magnitude units (m.u.) lower than at the EUS stations. The ... |

| This is the first SDCS report published incorporating data from Oak Springs Butte, Nevada (OB2NV) and NT-NV, two of the three stations at the Nevada Test Site. The third station, NT2NV is not yet operational. Included in this report are geologic surveys of the sites. Unfortunately, the data from these two new sites is unuseable in the hypocenter determination due to their close proximity to the event, the same being ... |
