Crustal structure and the seismogenic environment in Yunnan imaged by double-difference tomography
The large-scale faulting and earthquake activities that developed extensively in the Yunnan area are associated with the collision of India and Eurasia. The fine crustal structure can provide a better understanding of the crustal deformation, seismogenic

A seismic model for crustal structure in North China Craton
We present a digital crustal model in North China Craton (NCC). The construction of crustal model is based on digitization of original seismic sounding profiles, and new results of three-dimensional structure images of receiver functions.

Seismic traveltime inversion for 2-D crustal velocity structure [PDF]
SUMMARY A method of seismic traveltime inversion for simultaneous determination of 2-D velocity and interface structure is presented that is applicable to any type of body-wave seismic data. The advantage of inversion, as opposed to trial-and-error forward modelling, is that it provides estimates of model parameter resolution, uncertainty and non ...

Crustal velocity structure north of the Mendocino Triple Junction
A 140‐km‐long refraction/wide‐angle reflection profile recently recorded by Stanford University and the U. S. Geological Survey imaged the subducting Gorda slab beneath northern California. The profile, which is subparallel to the coast from Cape Mendocino northward, indicates that the North American plate is 13‐ to 14‐km‐thick along the coast north of

Through inversion of fundamental mode group velocities of Love and Rayleigh waves, we study the crustal and subcrustal structure across the central Deccan Volcanic Province (DVP), which is one of the world’s largest terrestrial flood basalts.

Structural Characteristics of Moho Surface Based on Time Series Function of Natural Earthquakes
Remote sensing is a non-contact, long-distance detection technology. The reflection characteristics of a seismic wave can be used to detect remote and non-contact targets.

Structure Along the Martian Dichotomy Constrained by Rayleigh and Love Waves and Their Overtones
Using seismic recordings of event S1222a, we measure dispersion curves of Rayleigh and Love waves, including their first overtones, and invert these for shear velocity (VS) and radial anisotropic structure of the Martian crust.
