US Surface Wave Dispersion Maps


China/Tibet Surface Wave Dispersion Maps

(1) Phase velocity maps in E. Asia including China and periphery regions from 8-70 sec period for Rayleigh wave phase velocities and 8-50 sec period for Rayleigh wave group velocities.. Maps derive from ambient noise tomography and earthquake tomography.
