Offshore Subduction Zone Structure and Seismicity Along Pacific Northwest: From the Gorda Plate to the Queen Charlotte Fault
Date: 4/24/2019
Time: 4:15 PM to 5:30 PM
Room: Puget Sound
The Cascadia subduction zone extends along the Pacific Northwest from Cape Mendocino in the south to northern Vancouver Island in the north. However, convergence continues farther north beneath Haida Gwaii along the Queen Charlotte Fault, where the Pacific and North America plates meet. Across this entire area, several oceanic plates (Explorer, Juan de Fuca, Gorda, Pacific) and one continental plate (North America) interact forming a myriad of structures and a complex stress regime, with most of the important tectonic boundaries and associated seismicity located offshore. In this session we invite contributions that focus on investigating the offshore structure and convergent tectonics along the Cascadia subduction zone and the Queen Charlotte Fault using marine geophysical data, especially those that are centered on or include active and/or passive source seismic studies. We also welcome contributions that use other observational or modeling techniques to characterize stress or deformation along the margin and those that that summarize past, present and future offshore instrument deployments along the Pacific Northwest.
