An Abrupt Transition in the Mechanical Response of the Upper Crust to Transpression along the Queen Charlotte Fault

Creator:

Tréhu, Anne M., Scheidhauer, Maren, Rohr, Kristin M. M., Tikoff, Basil, Walton, Maureen A. L., Gulick, Sean P. S., and Roland, Emily C.

Abstract:

The Queen Charlotte Fault (QCF) is a major strike-slip fault that forms the boundary between the Pacific and North American plates from 51° to 58° N. Near 53.2° N, the angle of oblique convergence predicted by the Mid-Ocean Ridge VELocity (MORVEL) interplate pole of rotation decreases from >15° in the...

Basement and Regional Structure Along Strike of the Queen Charlotte Fault in the Context of Modern and Historical Earthquake Ruptures

Creator:

Walton, Maureen A. L., Gulick, Sean P. S., Haeussler, Peter J., Roland, Emily C., and Tréhu, Anne M.

Abstract:

The Queen Charlotte fault (QCF) is a dextral transform system located offshore of southeastern Alaska and western Canada, accommodating ∼4.4 cm/yr of relative motion between the Pacific and North American plates. Oblique convergence along the fault increases southward, and how this convergence is accommodated is still debated. Using seismic reflection...
