Data Services Products: EMC-ORLA2022 A 3-D crustal shear wave velocity model and Moho map below the Semail Ophiolite, eastern Arabia

Summary

ORLA2022 is a radially anisotropic crustal shear wave velocity model, parameterized in terms of isotropic S velocity (Voigt average) and the radial anisotropy RAD [Vsh-Vsv; km/s]. ORLA stands for “Oman Rayleigh-Love Ambient Noise” based velocity model.

Data Set Description ORLA2022 is based on Rayleigh and Love wave phase velocity dispersion measurements using ambient seismic noise which were inverted for radially anisotropic shear wave velocity over depth. Phase velocity dispersion curves were calculated from continuous data from the temporary Cool seismic network (Weidle, et al., 2013) and eighteen local permanent stations from the Oman Earthquake Monitoring Centre, the Dubai seismic network and the Global Seismographic Network.
