Computing Green's Functions from Ambient Noise Recorded by Accelerometers and Analog, Broadband, and Narrow-Band Seismometers
The objective of our study is to supplement the regional P / S 3-D velocity model in the Reno basin with shear-wave velocity models derived from ambient noise interferometry (Aki 1957; Claerbout 1968; Shapiro et al. 2005; ...
Simulation of Seismic?Wave Propagation through Geometrically Complex Basins: The Dead Sea Basin
The Dead Sea Transform (DST) is the source for some of the largest earthquakes in the eastern Mediterranean. The seismic hazard presented by the DST threatens the Israeli, Palestinian, and Jordanian populations alike. ...
Depth to bedrock using gravimetry in the Reno and Carson City, Nevada, area basins
Sedimentary basins can trap earthquake surface waves and amplify the magnitude and lengthen the duration of seismic shaking at the surface. Poor existing gravity and well-data coverage of the basins below the rapidly growing ...
2D Analysis of Earthquake Ground Motion in Haifa Bay, Israel
We study the earthquake response of the Zevulun Valley basin, underlying northern Israel’s largest urban area, with 2D viscoelastic seismic modeling of a detailed geological section. We found that amplification of the ...
Improvements on Computation of Phase Velocities of Rayleigh Waves Based on the Generalized R/T Coefficient Method
Among many improvements on phase velocity computation of Rayleigh waves in a layered Earth model, the methods based on reflection and transmission (R/T) coefficients produce stable and accurate phase velocities for both ...
A seismic reflection image for the base of a tectonic plate
Plate tectonics successfully describes the surface of Earth as a mosaic of moving lithospheric plates. But it is not clear what happens at the base of the plates, the lithosphere–asthenosphere boundary (LAB). The LAB has ...
Shallow Shear Velocity and Seismic Microzonation of the Urban Las Vegas, Nevada, Basin
Las Vegas Valley has a rapidly growing population exceeding 1.5 million, subject to significant seismic risk. Surveys of shallow shear velocity performed in the Las Vegas urban area included a 13-km-long transect parallel ...
Station Delays, Their Standard Deviations, and Event Relocations in the Reno-Area Basin from a Dense Deployment During the 2008 West Reno Earthquake Swarm
The Nevada Seismological Laboratory (NSL) conducted a citizen volunteer multiple-instrument temporary deployment using 90 USArray Flexible Array single-channel RefTek RT-125A (Texan) recorders. Stations were deployed at ...
New constraints on fault architecture, slip rates, and strain partitioning beneath Pyramid Lake, Nevada
A seismic compressed high-intensity radar pulse (CHIRP) survey of Pyramid Lake, Nevada, defines fault architecture and distribution within a key sector of the northern Walker Lane belt. More than 500 line-kilometers of ...
