1. Investigation of Deep Seismic Reflections Beneath the Forearc in the South Central Chile Subduction Zone

Creator:: Zhang, Edward
Abstract:: The south central Chilean margin is one of the most seismically active subduction zones on Earth, generating some of the largest earthquakes on the planet, including the largest ever recorded in 1960 near Valdivia, Chile (Mw 9.5). Using the 15 km streamer and 6600 in3 tuned seismic airgun array aboard...

2. A 3-D Tomographic Model of the P-wave Velocity Structure of the Central Cascadia Forearc

Creator:: Kenyon, Christopher Bradford
Abstract:: Signals from the R/V Langseth’s tuned airgun array were recorded on an array of 33 EarthScope FlexArray seismometers deployed in the Oregon Coast Range from 43.5° to 45°N as part of the 2012 Ridge2Trench experiment to image the structure of the Juan de Fuca plate. This segment of the Juan...

3. Finite difference wavefield modeling of large-aperture data from the 1993 Mendocino Triple Junction Seismic Experiment

Creator:: Lendl, Christof
Abstract:: This thesis presents elastic finite difference simulations of two dimensional wavefield propagation for line-9, recorded during the 1993 part of the multi-institutional, multi-year Mendocino Triple Junction (MTJ) Seismic Experiment. Line-9 is a high-resolution, large-aperture seismic profile oriented in north-south direction, extending from the subduction regime north of the MTJ to...
