Existing lithospheric velocity models exhibit similar structures typically associated with the first-order tectonic features, with dissimilarities due to different data and methods used in model generation. The quantification of model structural simi

Surface-wave inversion is a powerful tool for revealing the Earth’s internal structure. However, aside from shear-wave velocity (vS), other parameters can influence the inversion outcomes, yet these have not been systematically discussed. This stud

Data-driven full-waveform inversion shows great potential for subsurface velocity estimation, but its accuracy is often hindered by susceptibility to local minima and the inherent characteristics of seismic data. Seismic shot gathers typically exhibi

The Meishan-Chiayi area of western Taiwan has a large probability of producing a major earthquake in the near future. Historically, one of the largest and most damaging of Taiwan’s earthquakes occurred there. It is, therefore, important to have a w

This work is devoted to development of an automatic algorithm for determining the velocity model from the data of the field seismic profile. First of all total energy of received signal and the positions of the first arrivals of reflected waves has t

The geological section of Eastern and Western Siberia is a complex object for a seismic exploration. The reason for this is the extremely high variability of the upper part of the section lithology, rough terrain, and permafrost rocks. This paper del
