Sensitivity of the close-in seismic source function to rock properties. (Condensed version)
- Los Alamos National Lab., NM (United States)
This paper presents a condensed version of a full report of the same title by App, 1993, which details work in progress on the systematic investigation of parameters affecting remote identification of underground nuclear tests. The objective of this investigation is to determine and evaluate how rock properties near the source of an explosion influence the close-in seismic source function. In this study, the overshoot and steady state value of the reduced displacement potential (RDP) and the corner frequency and rolloff of the reduced velocity potential (RVP) spectra are properties of the source function used to measure effect. A series of one-dimensional calculations are made with the computational mesh divided into six phenomenological regions.
