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

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 (Hammond et al., 2011) and the Young Conjugate Margins Lab in the Gulf of Aden network (Leroy et al., 2007) and are publicly available throughEarthScope Data Services.

The repository consists of three files:

SKS_ALL.csv

SKS_NULL_ALL.csv

stations_all.csv

The first file provides individual shear-wave splitting results reported in the study for the SKS phase. The columns are as follows: 

Station longitude

Station latitude

Orientation of the fast split shear wave (φ)

Time delay between the fast and slow shear waves (dt)

Error in phi

Error in dt

Event longitude

Event latitude

Event backazimuth

Distance in degrees from event-station

Event code

Station name

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: 

Station longitude

Station latitude

Event longitude

Event latitude

Event backazimuth

Distance in degrees from event-station

Event code

Station name

The station file contains the station name, the station latitude, station longitude and station elevation in km above sea level.
