SKS measurements and null measurements for seismic stations in Eritrea and Yemen

<p>These files relate to "Channelized mantle flow through the Afar Triple Junction and around the Arabian plate: evidence from seismic anisotropy" by Gauntlett et al. (2024). Original seismic waveforms are from the Eritrea Seismic Project (<a href="https://doi.org/10.7914/sn/5h_2011">Hammond et al., 2011</a>) and the Young Conjugate Margins Lab in the Gulf of Aden network (<a href="10.7914/SN/XW_2009">Leroy et al., 2007</a>) and are publicly available through<a href="http://service.iris.edu/fdsnws/dataselect/1/">EarthScope Data Services</a>.</p> <p>The repository consists of three files:</p> <ol> <li>SKS_ALL.csv</li> <li>SKS_NULL_ALL.csv</li> <li>stations_all.csv</li> </ol> <p>The first file provides individual shear-wave splitting results reported in the study for the SKS phase. The columns are as follows:&nbsp;</p> <ul> <li>Station longitude</li> <li>Station latitude</li> <li>Orientation of the fast split shear wave (&phi;)</li> <li>Time delay between the fast and slow shear waves (dt)</li> <li>Error in phi</li> <li>Error in dt</li> <li>Event longitude</li> <li>Event latitude</li> <li>Event backazimuth</li> <li>Distance in degrees from event-station</li> <li>Event code</li> <li>Station name</li> </ul> <p>The second file provides information on null results reported in the study, where no shear-wave splitting is observed for the SKS phase. The columns are as follows:&nbsp;</p> <ul> <li>Station longitude</li> <li>Station latitude</li> <li>Event longitude</li> <li>Event latitude</li> <li>Event backazimuth</li> <li>Distance in degrees from event-station</li> <li>Event code</li> <li>Station name</li> </ul> <p>The station file contains the station name, the station latitude, station longitude and station elevation in km above sea level.&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p> <p>&nbsp;</p>
