▪ Abstract Cenozoic extension in the western United States presents a complex interrelation
of extension, volcanism, and plate boundary tectonics that defeats simple notions of “active” …

The central and southern Coast Ranges of California coincide with the broad Pacific–North
American plate boundary. The ranges formed during the transform regime, but show little …

An In-Depth Introduction to Geothermal Energy Addressing significant changes in the
energy markets since the first edition, Geothermal Energy: Renewable Energy and the …

Crustal structure along a 140 km long profile across the San Andreas Fault (SAF) in
southern California was imaged by stacking teleseismic P–S converted phases recorded by …

The prevalent model for ductile shear zones assumes that they develop by progressive
simple shearing, resulting in a monoclinic fabric in which the vorticity vector is parallel to the …

Fluids associated with the San Andreas and companion faults in central and south-central
California have high3He/4He ratios. The lack of correlation between helium isotopes and …

This study examines the three‐dimensional velocity structure in a 60‐by 80‐km region
containing the Parkfield segment of the San Andreas fault. We use local earthquake and …

The crust around the rupture zone of the 1992 Landers earthquake has continued to deform
in the years following the earthquake at rates∼ 3 times greater than pre‐earthquake rates …

Slab detachment (or breakoff) has been proposed as a cause of temperature‐related
processes associated with subduction, such as postcollisional magmatism, mineralization …

Activity in moderate-size earthquakes accelerated in the several decades before the large
California earthquakes of 1989, 1906 and 1868. This type of precursor seems to require the …
