Subduction zones

Marine electromagnetic (EM) geophysics is an up-and-coming branch of the geosciences that is allowing for the advancement in our understanding of key properties of the oceanic lithosphere and subduction dynamics, particularly in how deformation manifests geophysically and how it…

Recent advances in seismic instrumentation have allowed researchers to undertake focused investigations of regions previously inaccessible. From the bottom of the sea to the coldest, driest places on earth, we are now able to deploy seismometers to remote locations and be certai…

Advances in seismology allow us to obtain "high-resolution" images of the Earth's subsurface. This dissertation summarizes the results of three seismic studies on three different continents, with the aim of better understanding the crust and upper mantle structure of seemingly d…

The Philippine Sea Plate has been surrounded by subduction zones throughout Cenozoic time due to the convergence of the Eurasian, Pacific and Indian-Australian plates. Existing Philippine Sea Plate reconstructions have been made based primarily on magnetic lineations produced by…

Geographically, the Indonesian archipelago is often divided into eastern and western parts, the boundary between them being placed at the 200 m bathymetric contours passing through the Makassar Strait in the north to Lombok Strait in the south. In this study, a new subdivision i…
