Depth of burial experiments at Balapan

PDF Version Also Available for Download.

Description

We report of a series of experiments designed to discriminate underground explosion sources at various depths by means of their seismic signatures at regional distances. This series was a joint effort of the US Department of Energy (DOE), the US Defense Special Weapons Agency (DSWA), and the National Nuclear Center of the Republic of Kazakhstan (NNC). The series consisted of three 25-ton explosions, at depths of 55 m, 300 m, and 50 m. In addition, a 5-ton checkout explosion was fired at a depth of 630 m, and small-scale explosions at each site were carried out so that the empirical ... continued below

Description

We report of a series of experiments designed to discriminate underground explosion sources at various depths by means of their seismic signatures at regional distances. This series was a joint effort of the US Department of Energy (DOE), the US Defense Special Weapons Agency (DSWA), and the National Nuclear Center of the Republic of Kazakhstan (NNC). The series consisted of three 25-ton explosions, at depths of 55 m, 300 m, and 50 m. In addition, a 5-ton checkout explosion was fired at a depth of 630 m, and small-scale explosions at each site were carried out so that the empirical Green`s functions could be derived. Broadband and short-period seismic data were recorded at an eight-station network within Kazakhstan, at nominal ranges varying from 100-1500 km, and with good azimuthal coverage for regional phases. In addition, seismic measurements were made at former NRDC sites (BAY and KKL), infrasound recordings were made at the cross array at Kurchatov, and close-in seismic measurements were also made at ranges from ground zero to 20 km. Although the main objective of this series was to study depth-of- burial (DOB) effects on the excitation of regional phases such as LG and RG, and to determine whether peaks in the coda spectral shape correlate well with DOB, a secondary objective was to help calibrate the site of the Kazakhstan seismic network, especially the primary IMS station at MAKanchi, and the auxiliary IMS stations at KURchatov and AKTyubinsk.
