Surface-wave dispersion calculations for layered Earth models enable fast forward modelling, inversion and tomography workflows but can be time-consuming without a validated tool.
Compute dispersion curves for a simple gradient model and plot the resulting phase and group velocities.
High-intent search queries and answers about installing and using this skill.
You compute surface-wave dispersion curves by inputting a layered velocity profile into the Skill, which uses disba to calculate phase and group velocities for Rayleigh and Love waves across multiple modes.
Phase velocity measures the speed of individual wave phases, while group velocity measures the speed of wave energy packets. This Skill computes both for Rayleigh and Love waves to support tomography workflows.
Yes, you can calculate sensitivity kernels for depth resolution. The Skill implements disba PhaseSensitivity to generate kernels needed for inversion workflows and assessing model sensitivity across velocity profiles.
Yes, the tool supports a half-space convention for layered Earth models. It processes velocity profiles using disba and NumPy to output phase and group dispersion curves for Rayleigh and Love waves.
The best way is to compute phase and group velocities for each velocity profile individually, then plot the resulting dispersion curves side-by-side to assess model sensitivity and variations.
Yes, you need NumPy installed. The Skill depends on both disba and NumPy to execute PhaseDispersion, GroupDispersion, and PhaseSensitivity calculations for layered Earth models.
