Ps receiver function imaging of crustal structure and Moho topography beneath the Northeast Caribbean.
… to ~30 km in the east, which we interpret as the Moho. We also image a feature at ~80 km, which we conclude to be a subducting North America (NA) slab pushing against the Caribbean lithosphere. The next step in seismological studies of the Northeast Caribbean region is seismic tomography using …

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 …

Metacognition and MoHO collide: Creating effective tutor and mentoring programs for college students on academic probation
… were trained in the Model of Human Occupation (MoHO) theory and metacognitive strategies. An assessment derived from theoretical underpinnings of MoHO was completed by students and facilitated by tutors and mentors exploring self-perception of motivation, habituation and performance in …

Seismic investigation of the Matador Arch and Central Basin Platform
… in western Texas have on the topography of the Moho and distinct boundaries in the mid-to-upper crust. Seismic data was processed using the traditional and wavefield iterative deconvolution receiver function methods before being stacked. The Moho and midcrustal discontinuity both deepen in the …

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 …

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 …

The CAFE Experiment : a joint seismic and MT investigation of the Cascadia Subduction System
… we clearly image the top of the slab and oceanic Moho, as well as a velocity increase corresponding to the eclogitization of the hydrated upper crust. A deeper velocity increase is interpreted as the eclogitization of metastable gabbros, assisted by fluids released from the dehydration of upper …

Receiver function study in northeast Tibet and adjacent boundaries
… stations, we provided a detailed image of the Moho geometry and constraints on the lithosphere-asthenosphere boundaries (LAB). The average crustal thickness is about 50km for the northeastern corner of the Tibetan plateau. The deepest Moho is found along the Kunlun Fault zone in the northern …

Seismic study of the crust and upper mantle structure in eastern Asia using ambient noise correlation and earthquake data
… 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. Significant …

Seismic imaging of the lithosphere-asthenosphere boundary with a dense broadband array in central California
… in Sp arrivals near and shallower than the Moho are consistent with a previously imaged west dipping sub-crustal shear zone extending down to about 30 km depth beneath the Great Valley. The Moho detected 45 km below the Sierra Nevada foothills shows that at least locally there is not a Moho …

A search for layering in the oceanic crust
… seismic signature of the crust/mantle boundary (Moho) is a prominent event on multichannel seismic (MCS) reflection data. In the Western North Atlantic, the character of the Moho reflection event varies from a single well-defined phase to a more complex event consisting of two or more overlapping …

Der obere Mantel in der Eifel-Region untersucht mit der Receiver Function Methode
… Analyse ergab klare Konversionen von der Moho und den beiden Manteldiskontinuitäten in 410 km und 660 km Tiefe, sowie Hinweise auf einen Mantel-Plume in der Region der Eifel. Die Moho wurde bei ungefähr 30 km Tiefe beobachtet und zeigt nur geringe Variationen im Bereich des Netzwerkes. Die …

Participants in both groups completed the Self-Assessment of Clinical Reflection and …

Crustal velocity structure in the southern coast belt, British Columbia, from a seismic refraction survey

A geophysical study of the earth's crust in central Virginia with implications for lower crustal reflections and Appalachian crustal structure
