Abstract

Tectonic strain release is one of the most important secondary sources associated with underground nuclear explosions. Various studies have been carried out on the properties of this secondary source (e.g., Wallace et al., 1983, 1985; Cohee and Lay, 1988; Ekstroem and Richards, 1994). In such studies the moment tensor approach (e.g., Stump and Johnson, 1981, 1984; Stump, 1987; Johnson, 1988; Patton, 1988; Vasco, 1989, 1990) is of special interest.
