In a recent study we used the Monte Carlo simulation method to evaluate the ground-motion uncertainty of the 2002 update of the California probabilistic seismic hazard model. The resulting ground-motion distribution is used in this article to ev[...]

Probabilistic seismic hazard analysis (PSHA) is classically performed through the Cornell approach by using a uniform earthquake distribution over the source area and a given magnitude range. This study aims at extending the PSHA approach to the[...]

Conventional probabilistic seismic-hazard assessment (PSHA) is difficult to apply in regions lacking sufficient information concerning geological setting, active faults, and so forth. Also, for a site-specific PSHA, site effects arising from bot[...]

We undertake the first New Zealand-based pilot study to investigate the use of ancient precariously balanced rocks (rocks that are unstably balanced on top of a pedestal) as a criteria for testing estimates of earthquake shaking from probabilist[...]

We used local earthquakes recorded in central Italy during the 1997– 1998 Umbria-Marche sequence to analyze the frequency dependence of the S-wave radiation pattern. We rotated the north–south and east–west ground-motion components into radial a[...]

In areas of moderate to low seismic activity there is commonly a lack of recorded strong ground motion. As a consequence, the prediction of ground motion expected for hypothetical future earthquakes is often performed by employing empirical mode[...]

Is the random variability of ground motions for a single station less than that obtained by regression analyses of ground-motion data recorded over a broad network of sites? This question has important implications for seismic design of critical[...]

What can be learned about absolute site effects on ground motions, with no geotechnical information available, in a very poorly instrumented region? In addition, can reliable source spectra be computed at a temporary deployment? These challenges[...]

Analysis of strong-motion instrument recordings in Seattle, Washington, resulting from the 2002 Mw 7.9 Denali, Alaska, earthquake reveals that amplification in the 0.2- to 1.0-Hz frequency band is largely governed by the shallow sediments both i[...]

Simple spectral ratio (SSR) and horizontal-to-vertical (H/V) site- response estimates at 47 sites in the Puget Lowland of Washington State document significant attenuation of 1.5- to 20-Hz shear waves within sedimentary basins there. Amplitudes [...]

A dataset comprising some 389 strong- and weak-motion records for 69 events from the Burakin 2001–2002 earthquake swarm, and additional recent events, is compiled to develop a regional ground-motion model for the Yilgarn Craton, southwestern Wes[...]

The motion of a building depends on the excitation, the coupling of the building to the ground, and the mechanical properties of the building. We separate the building response from the excitation and the ground coupling by deconvolving the moti[...]

The earthquake catalog in southern Iceland between 20.25° W and 21.3° W is complete down to approximately Mw 0 and shows no evidence for magnitude shifts as a function of time since 1991. This means that 6902 earthquakes (M ≥ –0.1, depth ≤ 20 km[...]

Regional depth phase modeling is a useful technique to constrain earthquake focal depths for events within sparse networks. We demonstrate how regional depth phases can be used to obtain focal depths for hundreds of earthquakes with mN ≥2.8 that[...]

A major problem with time-domain measurements of seismic surface waves is the significant effect of nondispersed Rayleigh waves and Airy phases, which can occur at both regional and teleseismic distances. This article derives a time-domain metho[...]
