GPS seismology

GPS seismology uses convential geodetic models to analyze GPS data at high sampling rates, such as 1 Hz. GPS seismology results are shown for the Denali, San Simeon, Tokachi-oki, and Chuetsu earthquakes. Records for these earthquakes indicate that GPS is an excellent instrument for measuring large displacements near earthquake ruptures. GPS systems can be improved for seismic applications if th...

Statistical Seismology

Stochastic models with an increasing component of physical reasoning have been slowly gaining acceptance over the last two decades. The subject of statistical seismology aims to bridge the gap between physics-based models without statistics, and statistics-based models without physics. This volume, which is based largely on papers presented at the 3rd International Workshop on Statistical Seism...

Seismology and CTBT Verification

It is well-known that the design and production of nuclear weapons required major efforts in scientific research and engineering, with a supporting infrastructure of weapons laboratories. Less well-known, is that scientific research and development have also played an important role in nuclear arms control. In this paper, my purpose is to explain the role of seismology in treaty verification; t...

I nc lu sion of-the Vik ing data arcs altered the Mart i an geoid features, as defined by previous short-arc analysis techniques of Mariner 9 data, by about 80 meters in the Southern Hemisphere 1 and about 140 meters i ...
