Variability of displacement at a point: Implications for earthquake‐size distribution and rupture hazard on faults Variability of displacement at a point: Implications for earthquake‐size distribution and rupture hazard on faults
To investigate the nature of earthquake‐magnitude distributions on faults, we compare the interevent variability of surface displacement at a point on a fault from a composite global data set of paleoseismic observations with the variability expected from two prevailing magnitude–frequency distributions: the truncated‐exponential model and the characteristic‐earthquake model. We use...

Normal-faulting slip maxima and stress-drop variability: A geological perspective Normal-faulting slip maxima and stress-drop variability: A geological perspective
We present an empirical estimate of maximum slip in continental normal-faulting earthquakes and present evidence that stress drop in intraplate extensional environments is dependent on fault maturity. A survey of reported slip in historical earthquakes globally and in latest Quaternary paleoearthquakes in the Western Cordillera of the United States indicates maximum vertical...

The most recent large earthquake on the Rodgers Creek fault, San Francisco bay area The most recent large earthquake on the Rodgers Creek fault, San Francisco bay area
The Rodgers Creek fault (RCF) is a principal component of the San Andreas fault system north of San Francisco. No evidence appears in the historical record of a large earthquake on the RCF, implying that the most recent earthquake (MRE) occurred before 1824, when a Franciscan mission was built near the fault at Sonoma, and probably before 1776, when a mission and presidio were built in...

Engineering geology considerations for park planning, Antelope Island State Park, Davis County, Utah Engineering geology considerations for park planning, Antelope Island State Park, Davis County, Utah
Report: 00-1 In the mid-1980s, historically high levels of Great Salt Lake caused damage to park facilities on Antelope Island and destroyed the causeway linking the park to the mainland. Information on the engineering geology of Antelope Islandcan be used to improve park facilities and reduce the risk from geologic hazards and poor construction conditions. Certain characteristics of the...

Quaternary tectonics of Utah with emphasis on earthquake-hazard characterization Quaternary tectonics of Utah with emphasis on earthquake-hazard characterization
This report consolidates and synthesizes information on Quaternary faulting, folding, and volcanism in Utah and characterizes recent tectonic activity throughout the state. The primary purpose is to provide a comprehensive reference on faultspecific seismic sources and surface rupture to facilitate the evaluation of earthquake hazards in Utah. Two 1:500,000-scale maps show Quaternary...
