Proceedings of Workshop XIV: earthquake hazards of the Puget Sound region, Washington Proceedings of Workshop XIV: earthquake hazards of the Puget Sound region, Washington
This conference, the fourteenth in a series sponsored by the Earthquake Hazards Reduction Program, was held October 13-15, 1980 at Lake Wilderness, Washington. The stated purpose of the conference was to assess progress and the state of knowledge of earthquake hazards in the Puget Sound region of Washington. The small size of the group and the pleasant informal setting of the Lake...

Triggering of large earthquakes by magma-chamber inflation, Izu Peninsula (Japan) Triggering of large earthquakes by magma-chamber inflation, Izu Peninsula (Japan)
A close spatial and temporal association between three aseismic uplift episodes and subsequent large (M ≈ 7) earthquakes on the Izu Peninsula, Japan, suggests a causal relation. Quaternary geology, as well as studies by other workers, indicates a volcanic origin for the observed uplift, and we use a simple inflation model constrained by leveling data to compute the expected increments in...

Reflection—refraction of general P- and type-I S-waves in elastic and anelastic solids Reflection—refraction of general P- and type-I S-waves in elastic and anelastic solids
The reflection and refraction of general (homogeneous or inhomogeneous) plane P and type-I S(SV) body waves incident on plane boundaries are considered for general linear viscoelastic solids. Reflection—refraction laws, physical characteristics of the waves, and the nature of critical angles are examined in detail at welded boundaries and a free surface. General visco-elasticity with no...

Application of wave field continuation to the inversion of refraction data Application of wave field continuation to the inversion of refraction data
Three examples of the inversion of refraction data by downward continuation illustrate the applicability of the method to field data. The first example is a refraction profile from the Mojave Desert, California. These data are spatially aliased and contain clear evidence of lateral inhomogeneity. The inversion in this case produces a broken image in the slowness‐depth domain due to the...

A note on transients in the SRO and ASRO long-period data A note on transients in the SRO and ASRO long-period data
Data users have occasionally observed pulse-like transients in the long-period waveforms recorded at the Seismic Research Observatories (SRO) and at the Modified High-Gain Long-Period (ASRO) stations. In a recent paper, Dziewonski et al (1981) reported transients associated with earthquake signals record at some SRO stations, and the authors ascribed these transients to an unpredictable...

Preliminary study of methods for upgrading USGS Antarctic seismological capability Preliminary study of methods for upgrading USGS Antarctic seismological capability
The purpose of this study is to evaluate potential methods for obtaining higher quality seismic data from Antarctica. Currently, USGS-sponsored WWSSN stations are located at Scott Base, Sanae Base, and at South Pole Station. Scott and Sanae Stations are located near the coast; data obtained from coastal installations are normally degraded by noise generated by ocean wave action on the...

Test and calibration of the Digital World-Wide Standardized Seismograph Test and calibration of the Digital World-Wide Standardized Seismograph
During the past decade there has been steady progress in the modernization of the global seismograph network operated by the U.S. Geological Survey (USGS). The World-Wide Standardized Seismograph Network (WWSSN) has been augmented by new stations with advanced instrumentation, including the Seismic Research Observatories (SRO) and the modified High-Gain Long-Period (ASRO) stations. One...

Design concepts for a Global Telemetered Seismograph Network Design concepts for a Global Telemetered Seismograph Network
This study represents a first step in developing an integrated, real-time global seismic data acquisition system a Global Telemetered Seismograph Network (GTSN). The principal objective of the GTSN will be to acquire reliable, high-quality, real-time seismic data for rapid location and analysis of seismic events. A secondary, but important, objective of the GTSN is to augment the...
