Digitalization of Lop Nor Explosion Seismograms from Kyrgyzstan Stations, and Establishment of the GT Calibration Explosion Working Group
Abstract
Data from the Lop Nor Test Site (LNTS) in the Peoples Republic of China is of interest to seismologists and the nuclear explosion monitoring community. Unfortunately, as most nuclear explosions from Lop Nor were detonated when there were very few digital seismic stations, there is a lack of digital waveforms at regional distances from this test site, though there are a significant number of legacy analog waveforms held in regional archives. This study recovered and digitally scanned analog paper seismograms of LNTS nuclear explosion seismograms held in the archive of the Institute of Seismology, National Academy of Sciences of the Kyrgyz Republic. The explosion seismograms were converted into digital waveforms that can be analyzed using modern digital techniques. The digitization technique takes into account individual system channel response, and the resulting waveforms rival modern digital seismograms. Regional seismograms were recovered from 35 different stations, that provide digital waveforms for 27 LNTS explosions that range in time from 1966 through1996. 258 seismograms, mostly 3-component, were completed in this project, resulting in a total of 773 digitized components. The seismogram scans, digitization, and many ancillary files accompany this report. These digitalized waveform arrivals represent travel paths of LNTS nuclear tests, at regional distances between 9 and 16 arc degrees.
