[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] I study the regional seismic phase attenuation to (1) infer rheology and temperature of the crust and uppermost mantle and to (2) develop reliable and ...

As part of the NorthEast Tibetan plateau Seismic (NETS) project, we performed receiver functions analysis across the northeastern Tibetan plateau and adjacent boundaries. Using the data of about 500 events obtained from ...

In the present dissertation, I describe two studies of the regional upper mantle shear wave velocity structure. In order to derive the absolute velocity structure of the upper mantle, I have applied surface wave tomography ...

The region encompassing the collision of northern Arabia with Eurasia is a tectonically heterogeneous region of distributed deformation. The northern Arabia plate is bounded to the west by the subducting Sinai plate and ...

I present three studies in two regions, both within the Central Andes. In both regions it is clear that there are significant variations in the subduction geometry. I have used surface wave tomography to investigate the ...

This dissertation focuses on two specific research topics: First, I study the lithospheric structure beneath E. Tibetan Plateau, using new data from INDEPTH-IV (INternational Deep Profiling of Tibet and the Himalayas) ...

Temperature and composition are two major causes for subsurface seismic anomalies. Positive temperature anomalies will lead to a reduction in both attenuation and velocity; however, compositional anomalies should not ...

The central Andean plateau is a prime region to study mantle flow above an active plateau margin, where it has been suggested that a link exists between plateau uplift and removal of the lower crust and lithospheric mantle. ...

Both body and surface wave tomography has been applied to some significant intraplate seismic zones to explore the cause of intraplate earthquakes. Pn tomography in the Central and Eastern United States reveals that the ...
