Abstract:

Some results are presented on work in the areas of station time corrections and P-wave velocity measurements at the Montana Large Aperture Seismic Array LASA. The value of the station correction in epicenter determination and beamforming is shown to be a significant factor in reducing gross errors in epicenters and thereby yielding a more accurate measurement of source and signal characteristics. Factors in the crust and mantle that contribute to the station errors are discussed and some inferences drawn from the data.
