Progress is reported on the following: interpretation of seismic data from the recent activities in Long Valley, California; theoretical study on a source model for the long-period events and volcanic tremor observed at Mount St. Helens; calculation of synthetic seismograms for the tremor source model; analysis of the Easter Island tremor records; testing and application of the Gaussian beam synthetic method to observations at Mount St. Helens; and field testing and development of a high-temperature borehole seismograph.
