Research in Seismology

Abstract

Research in seismology during the period April 1973 to March 1975 was concerned with the mechanisms and focal processes of Asian earthquakes, meteor impacts, and explosions. The seismicity, tectonics, and structure of the Afro-Eurasian junction, a complex region of relatively low seismic activity was clarified in terms of the breaking of an incoherent plate. Theoretical seismograms for real earth and source models were applied to earthquake dislocation sources and to low-magnitude earthquakes and crustal structure analyses in the northern Red Sea region. Generalized ray theory and reflection and transmission coefficients were applied to surface and shallow seismic sources in multi layered spherical earth models. Elastic wave motion processes across vertical discontinuities were studied.
