Historical Nuclear Event and Collapse Data From the Livermore Nevada Network Between 1979- 1992
Description:
Historical geophysical data recorded during the peak of nuclear testing is rare and limited. Efforts have been made to preserve and digitize data but have minimal quality control from decades of lost history and retiring personnel. Furthermore, recent research into the subsequent collapses of cavities is stifled by the lack of continuous records to investigate historical collapses.
The Livermore Nevada Network (LNN) was a 4-station seismic network in California, Nevada and Utah that recorded nuclear and tectonic events starting in the 1960s. Here, we present previously unreleased data from LNN between 1979 and 1992 containing over 100 recorded nuclear tests as well as over 50 collapses associated with a nuclear test. We will present the challenges and mitigation efforts we undertook to preserve and correct any errors in the digitization, waveform rotation and metadata.
