Integrated Study of Seismic and Infrasonic Signals From Sources in Southern Siberia, Eastern Kazakhstan and Western China

摘要

Our Final Report has two parts. The first part is a draft of a paper, submitted for publication, entitled 'A study of small magnitude seismic events during 1961-1989 on and near the Semipalatinsk Test Site, Kazakhstan.' In this paper, we have estimated origin time and assigned magnitude for 31 previously undocumented underground nuclear tests and for 19 of these 31 have obtained locations based on seismic signals. The second part is a draft of a paper, submitted for publication, entitled 'Infrasound Detection of Large Mining Blasts in Kazaktstan.' In this paper, we describe infrasonic observations recorded since October, 1997, at the Kurchatov Observatory in Kazakstan from large mining blasts in Kazakstan and Siberia.
