Determining local magnitude (M_L) in a manner that is uniform and internally consistent for earthquakes throughout California and the vicinity is an important component of the California Integrated Seismic Network (CISN). We present a new local magni

Lateral variation in crustal attenuation of California is calculated by inverting 25,330 synthetic Wood–Anderson amplitudes from the California Integrated Seismic Network (CISN) for site, source, and path effects. Two-dimensional attenuation ( q or

Large rock slope failures from near-vertical cliffs are an important geomorphic process driving the evolution of mountainous landscapes, particularly glacially steepened cliffs. The morphology and age of a 2·19 × 106 m3 rock avalanche deposit benea

By using small-to-moderate earthquakes located within ∼200 km of San Francisco, we characterize the scaling of the ground motions for frequencies ranging between 0.25 and 20 Hz, obtaining results for geometric spreading, Q ( f ), and site parameter

Summary Least-squares iterations with penaltji functions have been carried out on the fine structural Earth model CAL5, basedon observationsof eigenvibrations, surface waves and body waves. The penalty function formalism provides a more objective tre

We present an earthquake location algorithm, the Broadband Waveform Regional Earthquake Location Program(BW RELP), which utilizes phase onset times and wave azimuths recorded by three-component broadband seismic stations and an adaptive migrating gri

Effects of the July 10, 1996, rock fall at Happy Isles in Yosemite National Park, California, were unusual compared to most rock falls. Two main rock masses fell about 14 s apart from a 665-m-high cliff southeast of Glacier Point onto a talus slope a

INTRODUCTION As the deployment of broadband seismometers becomes increasingly common practice, the need for specific installation guidelines has emerged. Indeed, in order to operate efficiently, broadband instruments require a much more controlled en
