On the wobbles of phase-velocity dispersion curves

Petr Kolinsky et al.

Summary: The study presents a new method for calculating phase-velocity dispersion curves, highlighting the combined effects of dynamic and structural factors on wave propagation and interference. By comparing synthetics from different methods with measurements, the differences and impacts of dynamic phase velocity and structural phase velocity are revealed.

Azimuthal anisotropy in Bayesian surface wave tomography: application to northern Cascadia and Haida Gwaii, British Columbia

Jeremy M. Gosselin et al.

Summary: Surface wave tomography is a valuable tool for constraining azimuthal anisotropy at regional scales, but the sparse and uneven coverage of dispersion measurements pose challenges in uncertainty estimation. A Bayesian trans-dimensional inversion approach is used in this paper to better model azimuthal anisotropy using surface wave dispersion data, with a focus on considering data errors and avoiding subjective model regularization. The results provide insights into the structural context of tectonic dynamics in northern Cascadia and Haida Gwaii, highlighting the importance of considering azimuthal anisotropy in tomographic inversions for understanding seismic and tsunami hazards.

Surface-Wave Tomography of the Northern Canadian Cordillera Using Earthquake Rayleigh Wave Group Velocities

C. Esteve et al.

Summary: This study measures fundamental-mode Rayleigh wave group velocity dispersion from regional earthquakes and reveals azimuthally anisotropic structures in the crust and upper mantle of the northern Canadian Cordillera (NCC) using transdimensional Bayesian tomography. The results show coherent deformation with fast-axis alignment along major tectonic structures in the NCC. Anomalously low V-S structures and high-velocity regions at different depths in the crust and uppermost mantle are observed, providing insights into the thermal and tectonic processes in the region. Variations in the dip direction of high-velocity regions and the presence of low-velocity regions between faults are interpreted as reflecting different geodynamic processes beneath the NCC.
