Abstract
We present a uniform database of teleseismic shear-wave splitting (SWS) parameters for the Arabian plate. The SWS parameters, including the fast polarization orientation and splitting time, are measured based on a procedure that minimizes the energy on the transverse component. The majority of the data used to produce the SWS database were recorded by 157 seismic stations operated by the Saudi Geological Survey from 2010 to 2015. The rest of the data from 25 stations were obtained from the Incorporated Research Institutions for Seismology (IRIS) Data Management Center (DMC). About 4000 pairs of well-defined SKS, SKKS, and PKS parameters were obtained. Most of the stations show dominantly north-south (N-S) fast orientations. The station-averaged splitting times range from 0.45 to 1.84 s, with large splitting times in the western region of the Arabian Peninsula, and decrease eastward. The newly established database has an unprecedented spatial coverage and can be utilized by researchers in various fields to investigate crustal and mantle structure and dynamics beneath the Arabian plate.
