investigation of one dimensional upper crust velocity structure in northeast khorasan by the travel time inversion of p waves
north-east khorasan is one of the most active regions in the world because of is setting on the alpine-himalayan belt. historical and geological backgrounds suggest that this region has experienced many destructive earthquakes throughout history. compared with the historical background, the seismicity of the region, in the present century, is better known both from the macroseismic and instrume...
متن کاملTomographic inversion for three-dimensional anisotropy of Earth’s inner core
Seismological studies generally suggest that the Earth’s inner core is anisotropic and the anisotropic structure changes significantly both laterally and with depth. Previous body-wave studies of the inner core have relied on ray tracing or waveform modeling using one-dimensional (1D) models. Here we present non-linear tomographic inversions of the inner core anisotropy using three-dimensional ...
متن کاملGenetic Algorithms for Seismic Travel-Time Inversion
This paper attacks the problem of seismic travel-time inversion using genetic algorithms. Seismic surveying is usually a precondition to engineering and construction work in an area and travel-time inversion is a method of deducing sub-surface features from the measured travel-times of seismic waves. We consider both the one-dimensional and two-dimensional versions of the problem and explore di...
متن کاملA one-dimensional model for variations of longitudinal wave velocity under different thermal conditions
Ultrasonic testing is a versatile and important nondestructive testing method. In many industrial applications, ultrasonic testing is carried out at relatively high temperatures. Since the ultrasonic w...
متن کاملThree-dimensional solutions for general anisotropy
The Stroh formalism is extended to provide a new class of three-dimensional solutions for the generally anisotropic elastic material that have polynomial dependence on x3, but which have quite general form in x1; x2. The solutions are obtained by a sequence of partial integrations with respect to x3, starting from Stroh’s two-dimensional solution. At each stage, certain special functions have t...
