NA-SWS-1.1: A uniform database of teleseismic shear wave splitting measurements for North America
[1] This version of shear wave splitting (SWS) database (DB) for North America (NA) contains 6224 pairs of splitting parameters (fast polarization directions and splitting times) measured using all the available data recorded by digital broadband seismic stations over the period of 1980–2007 and archived at the Incorporated Research Institutions for Seismology Data Management Center. The measur...

متن کاملNull Detection in Shear-Wave Splitting Measurements
Shear-wave splitting measurements are widely used to analyze orientations of anisotropy. We compare two different shear-wave splitting techniques, which are generally assumed to give similar results. Using a synthetic test, which covers the whole backazimuthal range, we find characteristic differences, however, in fast-axis and delay-time estimates near Null directions between the rotation corr...
متن کاملDeclining Mountain Snowpack in Western North America*
JANUARY 2005 AMERICAN METEOROLOGICAL SOCIETY | ountain snowpack in western North America is a key component of the hydrologic cycle, storing water from the winter (when most precipitation falls) and releasing it in spring and early summer, when economic, environmental, and recreational demands for water throughout the West are frequently greatest. In most river basins of the West, especially in...
متن کاملMaking Reliable Shear-Wave Splitting Measurements
Shear-wave splitting (SWS) analysis using SKS, SKKS, and PKS (hereafter collectively called XKS) phases is one of the most commonly used techniques in structural seismology. In spite of the apparent simplicity in performing SWS measurements, large discrepancies in published SWS parameters (fast direction and splitting time) suggest that a significant portion of splitting parameters has been inc...
