Suppression of large earthquakes by stress shadows: A comparison of Coulomb and rate-and-state failure Suppression of large earthquakes by stress shadows: A comparison of Coulomb and rate-and-state failure
Stress shadows generated by California's two most recent great earthquakes (1857 Fort Tejon and 1906 San Francisco) substantially modified 19th and 20th century earthquake history in the Los Angeles basin and in the San Francisco Bay area. Simple Coulomb failure calculations, which assume that earthquakes can be modeled as static dislocations in an elastic half-space, have done quite...

Compilation of 29 sonic and density logs from 23 oil test wells in western Washington State Compilation of 29 sonic and density logs from 23 oil test wells in western Washington State
Three-dimensional velocity models for Puget Sound provide a means for better understanding the lateral variations in strong ground motions recorded during local earthquakes in Puget Lowland. We have compiled 29 sonic and density logs from 23 oil test wells to help us determine the geometry and physical properties of the Cenozoic basins in western Washington. The maximum depths sampled by...

The coseismic slip distributions of the 1940 and 1979 Imperial Valley, California, earthquakes and their implications The coseismic slip distributions of the 1940 and 1979 Imperial Valley, California, earthquakes and their implications
Geodetic arrays observed by the U.S. Coast and Geodetic Survey span the Imperial fault in southern California. For the 1940 M 7.1 Imperial Valley earthquake, a 1934–1941 triangulation network has sufficient resolution to allow inversion for the coseismic slip distribution on fault segments 5 to 25 km long extending from the surface to a depth of 9 km. The estimated right-lateral slip is...

The Loma Prieta, California, Earthquake of October 17, 1989: Forecasts The Loma Prieta, California, Earthquake of October 17, 1989: Forecasts
The magnitude (Mw) 6.9 Loma Prieta earthquake struck the San Francisco Bay region of central California at 5:04 p.m. P.d.t. on October 17, 1989, killing 62 people and generating billions of dollars in property damage. Scientists were not surprised by the occurrence of a destructive earthquake in this region and had, in fact, been attempting to forecast the location of the next large...

Chapter C. The Loma Prieta, California, Earthquake of October 17, 1989 - Building Structures Chapter C. The Loma Prieta, California, Earthquake of October 17, 1989 - Building Structures
Several approaches are used to assess the performance of the built environment following an earthquake -- preliminary damage surveys conducted by professionals, detailed studies of individual structures, and statistical analyses of groups of structures. Reports of damage that are issued by many organizations immediately following an earthquake play a key role in directing subsequent...

The Loma Prieta, California, earthquake of October 17, 1989: Landslides The Loma Prieta, California, earthquake of October 17, 1989: Landslides
Central California, in the vicinity of San Francisco and Monterey Bays, has a history of fatal and damaging landslides, triggered by heavy rainfall, coastal and stream erosion, construction activity, and earthquakes. The great 1906 San Francisco earthquake (MS=8.2-8.3) generated more than 10,000 landslides throughout an area of 32,000 km2; these landslides killed at least 11 people and...

The Loma Prieta, California, earthquake of October 17, 1989: Liquefaction The Loma Prieta, California, earthquake of October 17, 1989: Liquefaction
The 1989 Loma Prieta earthquake both reconfirmed the vulnerability of areas in the San Francisco-Monterey Bay region to liquefaction and provided an opportunity to test methodologies for predicting liquefaction that have been developed since the mid-1970's. This vulnerability is documented in the chapter edited by O'Rourke and by the investigators in this chapter who describe case...

Chapter B. The Loma Prieta, California, Earthquake of October 17, 1989 - Highway Systems Chapter B. The Loma Prieta, California, Earthquake of October 17, 1989 - Highway Systems
This paper summarizes the impact of the Loma Prieta earthquake on highway systems. City streets, urban freeways, county roads, state routes, and the national highway system were all affected. There was damage to bridges, roads, tunnels, and other highway structures. The most serious damage occurred in the cities of San Francisco and Oakland, 60 miles from the fault rupture. The cost to...

Experimental investigations regarding the use of sand as an inhibitor of air convection in deep seismic boreholes Experimental investigations regarding the use of sand as an inhibitor of air convection in deep seismic boreholes
Tilt has been the nemesis of horizontal long period seismology since its inception. Modern horizontal long period seismometers with their long natural periods are incredibly sensitive to tilt. They can sense tilts smaller than 10-11 radians. To most readers, this is just a very very small number, so we will begin with an example, which should help to illustrate just how small 10-11...
