2015/8/26
On June 8, 2008, at 12:25 GMT, a Mw 6.4 earthquake, the Movri Mountain earthquake, occurred in the area of northwest Peloponnese, western Greece. The epicenter was located in the municipality of Movri...
Empirical relationships of shear wave velocity,SPT-N value and vertical effective stress for different soils in Mashhad,Iran
Shear wave velocity Vertical effective stress Standard penetration test Downhole test, Empirical relations Mashhad Iran
2015/8/14
Shear wave velocity, Vs, is one of the important input parameters in seismic response analysis of the ground. Various methods have been examined to measure the soil Vs directly. Direct measurement of ...
Mantle lithosphere transition from the East European Craton to the Variscan Bohemian Massif imaged by shear-wave splitting
Seismic shear wave splitting focused on the structure of the upper mantle
2015/1/6
We analyse splitting of teleseismic shear waves recorded during the PASSEQ passive experiment (2006–2008) focused on the upper mantle structure across and around the Trans-European Suture Zone (TESZ)....
Validity of the Refraction Microtremors (ReMi) Method for Determining Shear Wave Velocities for Different Soil Types in Egypt
Refraction Microtremors ReMi Crosshole Downhole Shear Wave Egypt
2013/3/7
The Refraction Microtremor (ReMi) method is being used around the world by the geotechnical and geophysical community to determine shear-wave velocities. This is due to its faster, less expensive and ...
Retrieval of Moho-reflected shear wave arrivals from ambient seismic noise
Interferometry Body waves Crustal structure
2014/4/10
Theoretical studies on ambient seismic noise (ASN) predict that complete Green’s function between seismic stations can be retrieved from cross correlation. However, only fundamental mode surface waves...
