Sediments and tectonics of the Gorda-Juan de Fuca plate

Creator:: Phipps, James B.
Abstract:: Cores taken from the ridge areas of the Gorda-Juan de Fuca plate have a sedimentation rate that is appropriate for the study of late Quaternary stratigraphy. An analysis of the clay and silt mineralogy of the cores using X-ray diffraction methods and by noting changes in the foraminiferan-radiolarian abundances in...

Exploring Volcano-Tectonic Connections in Cascadia – Temporal Linkages between Tephra Deposition and Megathrust Earthquakes

Creator:: Gutierrez, Joel C.
Abstract:: Explosively erupting volcanoes and megathrust earthquakes (Mw 8+ magnitude) occur at subduction zones and adjacent volcanic arcs. Volcanic eruptions are observed occurring close in time to megathrust earthquakes in the historical record from at least the 18th century CE to present in locations globally, including Japan in 1707 CE (Chesley...

Testing spatial correlation of subduction interplate coupling and forearc morpho-tectonics

Creator:: Kaye, Grant David
Abstract:: The two largest earthquakes ever recorded, the 1964 M[subscript w] 9.2 Alaskan and 1960 M[subscript w] 9.5 Chilean, occurred on seismogenic plate interfaces at subduction zones. It has been theorized that the catastrophic failure of a locked zone along the contact between the downgoing slab and the upper plate causes...

Magnetotelluric Studies of Tectonic Systems and Volcanic Areas of North America

Creator:: Bowles-Martinez, Esteban
Abstract:: Magnetotellurics is used in two geologic settings on scales ranging from 1000-km tectonic structures to local features hundreds of meters wide. These areas are the Midcontinent Rift System (MRS) and its related mantle plume in the northern Midwestern United States and Newberry Volcano in central Oregon. The MRS study uses...

Hydro‐isostatic deflection and tectonic tilting in the central Andes: Initial results of a GPS survey of Lake Minchin shorelines

Creator:: Bills, Bruce G., de Silva, Shanaka L., Currey, Donald R., Emenger, Robert S., Lillquist, Karl D., Donnellan, Andrea, and Worden, Bruce
Abstract:: Sufficiently large lake loads provide a means of probing rheological stratification of the crust and upper mantle. Lake Minchin was the largest of the late Pleistocene pluvial lakes in the central Andes. Prominent shorelines, which formed during temporary still‐stands in the climatically driven lake level history, preserve records of lateral...

Investigation of Slip and Tectonics of the Blanco Transform Fault using High-resolution Ocean Bottom Seismic Data

Creator:: Kuna, Václav M.
Abstract:: The dissertation concentrates on seismicity of the Blanco Transform Fault (BTF), a 350-km-long oceanic transform fault (OTF) in the northeast Pacific Ocean. I analyze data collected during the Blanco Transform Fault OBS experiment, which comprised of a 1-year deployment of 55 three-component seismometers co-located with differential pressure gauges on and...

Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:: Davidson, Peter C.
Abstract:: Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...
