We describe a technique to derive first-order site-condition maps directly from topographic
data. For calibration, we use global 30 arc sec topographic data and VS 30 measurements …

We have produced a large set of broadband (0–10 Hz) synthetic seismograms for M w 9.0
earthquakes on the Cascadia megathrust by combining synthetic seismograms derived from …

Consideration of site conditions is a vital step in analyzing and predicting earthquake
ground motion. The importance of amplification by soil conditions has long been recognized …

Correlations between geologic units and shear-wave velocity form the basis of a series of
maps developed over the past 15 years to estimate the time-averaged shear-wave velocity …

Thirty-meter shear-wave velocity (VS 30) is commonly used to estimate near-surface
conditions for site classification, seismic site response, liquefaction analysis, and other …

Cone penetration test (CPT) and standard penetration test (SPT) are widely used for the site
specific evaluation of liquefaction potential and are getting increased use in the regional …

The geotechnical industry has widely adopted the refraction microtremor shear-wave
velocity measurement technique, which is accepted by building authorities for evaluation of …

The simulated annealing (SA) inversion technique has been successfully applied for solving
various nonlinear geophysical problems. Following previous developments, we modified the …

The simplified shear-wave velocity (Vs)–based procedure of liquefaction potential
assessment was basically developed for terrigenous deposits, whereas its applicability for …

Surface-wave methods are quite popular for site characterization in geotechnical
earthquake engineering. Among these techniques, a particular role is taken by passive …
