Supporting Information for ”Imaging widespread seismicity at mid-lower crustal depths beneath Long Beach, CA, with a dense seismic array: Evidence for a depth-dependent earthquake size
We present supporting material for the manuscript ”Imaging widespread seismicity at mid-lower crustal depths beneath Long Beach, CA, with a dense seismic array: Evidence for a depth-dependent earthquake size distribution”. The material contains three figures. The purpose of the figures is to illustrate the advantages of downward-continuing the data prior to back-projection, and to provide detai...
متن کاملImaging widespread seismicity at midlower crustal depths beneath Long Beach, CA, with a dense seismic array: Evidence for a depth-dependent earthquake size distribution
We use a dense seismic array composed of 5200 vertical geophones to monitor microseismicity in Long Beach, California. Poor signal-to-noise ratio due to anthropogenic activity is mitigated via downward-continuation of the recorded wavefield. The downward-continued data are continuously back projected to search for coherent arrivals from sources beneath the array, which reveals numerous, previou...
متن کاملSignificant seismic anisotropy beneath the southern Lhasa Terrane, Tibetan Plateau
[1] Shear wave splitting measurements using teleseismic PKS, SKKS, and SKS phases recorded by station LSA on the southern part of the Lhasa Terrane of the Tibetan Plateau reveal significant azimuthal anisotropy with a splitting time of up to 1.5 s, a conclusion that is contradictory to previous studies which suggested isotropy or weak anisotropy. In addition, systematic variations of the splitt...
متن کاملFortuna Tessera, Venus Evidence of Horizontal Convergence and Crustal Thickening
Structural and tectonic patterns mapped in Fortuna Tessera are interpreted to reflect a change in the style and intensity of deformation from east to west, beginning with simple tessera terrain at relatively low topographic elevations in the east and progressing through increasingly complex deformation patterns and higher topography to Maxwell Montes in the west. These morphologic and topograph...
متن کاملSeismic imaging of the downwelling Indian lithosphere beneath central Tibet.
A tomographic image of the upper mantle beneath central Tibet from INDEPTH data has revealed a subvertical high-velocity zone from approximately 100- to approximately 400-kilometers depth, located approximately south of the Bangong-Nujiang Suture. We interpret this zone to be downwelling Indian mantle lithosphere. This additional lithosphere would account for the total amount of shortening in t...
