Correlation migration for structural imaging using Gaussian beams is described for the inversion of passively recorded teleseismic waves. Gaussian beam migration is based on an overcomplete frame-based representation of the seismic wave field an[...]

Scalar moment rates estimated from a 146-year seismicity catalog agree, within uncertainties, with the deformation rate of the Basin and Range province determined by using space geodesy. Seismic-moment rates have been estimated from a new catalo[...]

Sets of well-preserved channels offset across the San Andreas fault (SAF) at the Van Matre Ranch (VMR) site in the northwestern Elkhorn Hills area of the Carrizo Plain offer the opportunity to measure slip rate and examine geomorphic development[...]

Field investigation and paleoseismic study constrain the offset and timing of recent large earthquakes on the Xidatan–Dongdatan segment of the strike-slip Kunlun fault, northern Tibet. Displaced terrace risers and gullies preserved on the lowest[...]

We study the surface deformation associated with the 24 February 2004 Al Hoceima earthquake (Mw 6.4) that recently affected the Rif Mountains of Morocco. The coseismic displacement field is mapped using synthetic aperture radar interferometry (I[...]

To better understand the connection between earthquake production and geothermal/magmatic systems, we studied the extent of fluid-influenced faulting in the Long Valley volcanic region. We focused on a 100-km-wide circular area centered at the L[...]

The observed seismicity rate increase after large earthquakes in sites that are located several source lengths away from the mainshock centroid poses a major problem. This is because the static stress change induced by a mainshock in that region[...]

We have initially developed a time-independent forecast for southern California by smoothing the locations of magnitude 2 and larger earthquakes. We show that using small m ≥2 earthquakes gives a reasonably good prediction of m ≥5 earthquakes. O[...]

We defined a seismogenic model for central Italy based on three layers of sources and computed the relative seismic-hazard maps. One layer is constituted by individual structures liable to generate major earthquakes (M ≥5.5). We defined them as [...]

Paleoseismic evidence and seismic-hazard analysis suggest that the city of Rome, Italy, has experienced considerable earthquake ground motion since its establishment more than 2000 years ago. Seismic hazards in Rome are mainly associated with tw[...]

By means of borehole array recordings obtained at six stations from local events, we estimated coherency characteristics of body waves that propagate in a sedimentary layer–basement system in the Kanto region, Japan. The estimated coherence is c[...]

We utilize earthquake recordings at two broadband seismographs located on the coast of the Gulf of Mexico to estimate Q of the mantle wedge. From the data at a station situated in the Laguna Verde nuclear power plant (LVIG), about 100 km northwe[...]

The attenuation of shear waves propagating in the crust of northwestern Turkey has been investigated in the frequency range 1–10 Hz. A standard spectral inversion scheme is applied to a data set of 245 aftershocks (ML

Ground-motion prediction (attenuation) models predict the probability distributions of spectral acceleration values for a specified earthquake event. These models provide only marginal distributions, however; they do not specify correlations amo[...]

The horizontal-to-vertical (H/V) spectral ratio of seismic noise has become a widely used tool in microzonation over the last decade. However, attempts to provide standards for seismic-noise analysis have only recently been made. One point often[...]

This study utilized seismograms from the U.S. Geological Survey seismological station near Ely, Minnesota, at which 39 delay-fired explosions at the U.S. Steel Minntac iron mine in Mountain Iron, Minnesota, were recorded. The waveforms were anal[...]

Traditional local-earthquake location using a horizontally layered homogeneous velocity model is limited in its resolution and reliability due to the existence of frequently overlooked 3D complexity of the real Earth. During traditional 3D seism[...]

I prove three theorems on earthquake location in the laterally homogeneous, radially concentric layered earth showing that (1) epicenters of earthquakes are locatable without using numerical travel-time information, (2) focal-depth residuals cha[...]

The statistics of time delays between successive earthquakes has recently been claimed to be universal and to show the existence of clustering beyond the duration of aftershock bursts. We demonstrate that these claims are unjustified. Stochastic[...]

The Chi-Chi, Taiwan, earthquake of 20 September 1999 was preceded by a notable decrease of the regional seismicity rate. The anomalous period started in January 1999 and lasted about 9 months, up to the occurrence of the mainshock, as revealed f[...]

We demonstrate a case of using short-period, vertical-component seismograms alone to study the Archean crust. The approach is equivalent to conventional seismic reflection profiles except that high-frequency (up to 1.2 Hz) transmitted wave field[...]

Liquefaction of saturated soils and sediments documented during earthquakes shows an empirical relation log Rmax = 2.05 (±0.10) + 0.45 M, where Rmax is the liquefaction limit in meters (i.e., the maximum distance from liquefaction site to the hy[...]
