Abstract : Theoretical and observational research has been carried out in order to study tectonic strain. Theoretical calculations for a composite source model consisting of explosive and double couple components were compared to observed surface wave spectral ratios from underground nuclear explosions. A theoretical calculation is presented to explain the observed double couple component associated with tectonic stress release. Results from numerical calculations of induced flow behind island arcs and the associated tectonic stresses are presented. (Author)
