Seismic study of the crust and upper mantle structure in eastern Asia using ambient noise correlation and earthquake data
… and uppermost mantle P wave velocity and the depth of Moho discontinuity. This method addresses the trade-off issue between the media velocity and a discontinuity location. I apply this method to the eastern and southern margin of Tibetan Plateau, where the Moho depth changes rapidly. …

Crustal structure and tectonics of Borneo and Sulawesi: results from receiver function analysis and virtual deep seismic sounding
… phases to constrain seismic properties including Moho depth, V_S and V_P 〖/V〗_S. In the case of RFA, H-k stacking, migration and inversion are separately applied, with the ensemble of results producing robust estimates of crustal thickness in particular. The primary strength of VDSS is its ability …

Lithospheric Structure Across the Northern Canadian Cordillera from Teleseismic Receiver Functions
… between Earth’s crust and mantle is known as the Mohorovicic discontinuity (Moho). The depth of the Moho plays an important role in characterizing the overall structure of the crust and can be related to the tectonic setting of a region. Teleseismic P-wave receiver function techniques can provide …

Continental Tectonics from Dense Array Seismic Imaging: Intraplate Seismicity in Virginia and a Steep Cratonic Margin in Idaho
… Idaho shear zone. We found a 7 km offset in Moho depth, separating crust with different seismic velocities and Poisson's ratios. The crust beneath the Blue Mountains terranes is consistent with an intermediate lithology dominated by diorite. In the lower crust there is evidence of magmatic …

Crustal structure of the Eratosthenes Seamount, Cyprus and S. Turkey from an amphibian wide-angle seismic profile
… km and (3) an upper crustal reflection at 5 km depth beneath the ESM. Two land shots on Turkey, also recorded on Cyprus, airgun shots south of Cyprus and geological and previous seismic investigations provide the information to derive a layered velocity model beneath the Anatolian plateau and …

A study of the structure of the Belgian crust by Moho determination and local seismic tomography
… This will be achieved by determining the Moho depth and performing a local seismic tomography. The Moho is rather flat underneath Belgium with Moho depths ranging from 31 km underneath the Brabant Massif (BM) over 31-33 km underneath the Roer Valley Graben (RVG) and the Ardennes Allochthon …

Seismic imaging of the western Hellenic subduction zone : the relationship between slab composition, retreat rate, and overriding lithosphere genesis
… lithospheric structure. I find a continuous slab Moho across northern and southern Greece between ~40 and 80 km depth, with a gentle, trench-parallel component of dip accommodating the observed differential slab retreat. The overriding Moho is deepest beneath the northern Hellenides (35-40 km) and …

Vertical Motions at the Fringes of the Icelandic Plume
… well as a Bayesian, trans-dimensional algorithm. Moho depths thus obtained are combined with seismic wide-angle and deep reflection data to produce a comprehensive crustal thickness map of northwestern Europe. Moho depth is found to decrease from southeast (37 km) to northwest (26 km) in the …

Insight from thermochronology, magnetotellurics, and structural analysis into the tectonic evolution of the Ozark Dome-Illinois Basin region, Midcontinent USA
… structural relief across it, as manifested by depth changes in the Great Unconformity? What is the surface manifestation of the IB/OD boundary, and does it correlate with deeper structures? What is the character of fault-and-fold zones (both at the surface and at depth in the lithosphere) in …
