Seismic Investigations

of the Deep Earth

Imaging the Earth’s crustal and mantle structure by mining tens of terabytes of seismic data using computationally intensive techniques, including machine learning. Current projects include crustal and mantle structure beneath North America, initiation and development of rifted valleys in African and Asia, spatial and temporal distributions of earthquakes, and lithospheric imaging beneath the Tibetan Plateau associated with continental collision between the Indian and Eurasian plates. Major research tools include shear wave splitting analysis; receiver function stacking; seismic body and surface wave tomography; seismic wave attenuation measurements; gravity and magnetic data modeling; and deep machine learning using convolutional neural networks.
