Description
The shear-wave splitting measurements for western and central United States is a teleseismic shear-wave splitting (SWS) database based on all the data from all the broadband seismic stations in North America that contains over 16,000 pairs of well-defined (and manually checked) SWS measurements for the western and central United States (west of 90°W).
Table below shows the content of this database. The columns in the database are as follows (columns in bold are shown in table below) :
- Station_network name. The station name is padded with "x"s if it has less than 6 characters, and the network name is padded with a "y" if it has only one character
- Phase name (SKS, PKS, SKK which is SKKS)
- Event name (EQ + yr + ddd + hh + mm)
- Station latitude in degrees
- Station longitude in degrees
- phi, fast polarization direction in degree, measured clockwise from the North
- Standard deviation of the fast direction in degree
- dt, splitting time in second
- Standard deviation of the splitting time in second
- Back azimuth, measured clockwise from the North
- Modulo-90 degree back-azimuth
- Event latitude
- Event longitude
- Event depth
- Rank, measurement quality
- Longitude of XKS raypiercing point at 200 km depth
- Latitude of XKS raypiercing point at 200 km depth
