Three-dimensional seismic ray tracing leads to improved hypocenter locations and focal mechanism solutions. Relations of events to upper mantle structure to under the Aleutian arc are classified. Long-period P waves are very weak on HGLP seismograms of explosions, but long-period SV waves are seen. Long period body wave spectra can be used to fix the depth of crustal earthquakes. Body wave spectra, magnitudes, and focal mechanisms for events in from seismic zones of central Asia have been determined.
