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...

Long-Term Time-Dependent Probabilities for the Third Uniform California Earthquake Rupture Forecast (UCERF3)

Creator:: Field, Edward H., Biasi, Glenn P., Bird, Peter, Madden, Christopher, Dawson, Timothy E., Felzer, Karen R., Jackson, David D., Johnson, Kaj M., Jordan, Thomas H., Michael, Andrew J., Milner, Kevin R., Page, Morgan T., Parsons, Tom, Powers, Peter M., Shaw, Bruce E., Thatcher, Wayne R., Weldon, Ray J., II, and Zeng, Yuehua
Abstract:: The 2014 Working Group on California Earthquake Probabilities (WGCEP 2014) presents time-dependent earthquake probabilities for the third Uniform California Earthquake Rupture Forecast (UCERF3). Building on the UCERF3 time-independent model published previously, renewal models are utilized to represent elastic-rebound-implied probabilities. A new methodology has been developed that solves applicability issues in...

Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3) —The Time-Independent Model

Creator:: Field, Edward H., Arrowsmith, Ramon J., Biasi, Glenn P., Bird, Peter, Dawson, Timothy E., Felzer, Karen R., Jackson, David D., Johnson, Kaj M., Jordan, Thomas H., Madden, Christopher, Michael, Andrew J., Milner, Kevin R., Page, Morgan T., Parsons, Tom, Powers, Peter M., Shaw, Bruce E., Thatcher, Wayne R., Weldon, Ray J., II, and Zeng, Yuehua
Abstract:: The 2014 Working Group on California Earthquake Probabilities (WGCEP14) present the time-independent component of the Uniform California Earthquake Rupture Forecast, Version 3 (UCERF3), which provides authoritative estimates of the magnitude, location, and time-averaged frequency of potentially damaging earthquakes in California. The primary achievements have been to relax fault segmentation and...

Magnitude Limits of Subduction Zone Earthquakes

Creator:: Rong, Yufang, Jackson, David D., Magistrale, Harold, and Goldfinger, Chris
Abstract:: Maximum earthquake magnitude (m[subscript x]) is a critical parameter in seismic hazard and risk analysis. However, some recent large earthquakes have shown that most of the existing methods for estimating m[subscript x] are inadequate. Moreover, m[subscript x] itself is ill-defined because its meaning largely depends on the context, and it...

Source Parameter Scaling and the Cascadia Paleoseismic Record

Creator:: Tréhu, Anne M.
Abstract:: Several approaches to interpreting the Cascadia paleoseismic record are used to derive relationships between fault area, slip, and moment and to compare the results with the scaling relationships determined by Somerville et al. (2015) for recent subduction-zone events. In two models (CA12a and CA12b), taken from Goldfinger et al. (2012),...

Abstract:: This article summarizes the geotechnical effects of the 25 April 2015 M 7.8 Gorkha, Nepal, earthquake and aftershocks, as documented by a reconnaissance team that undertook a broad engineering and scientific assessment of the damage and collected perishable data for future analysis. Brief descriptions are provided of ground shaking, surface...

Validation of meter-scale surface faulting offset measurements from high-resolution topographic data

Creator:: Salisbury, J. Barrett, Haddad, D. E., Rockwell, T., Arrowsmith, J. R., Madugo, C., Zielke, O., and Scharer, K.
Abstract:: Studies of active fault zones have flourished with the availability of high-resolution topographic data, particularly where airborne light detection and ranging (lidar) and structure from motion (SfM) data sets provide a means to remotely analyze submeter-scale fault geomorphology. To determine surface offset at a point along a strike-slip earthquake rupture,...

Environmental and Ecological Effects of Ocean Renewable Energy Development: A Current Synthesis

Creator:: Boehlert, George W. and Gill, Andrew B.
Abstract:: Marine renewable energy promises to assist in the effort to reduce carbon emissions worldwide. As with any large-scale development in the marine environment, however, it comes with uncertainty about potential environmental impacts, most of which have not been adequately evaluated—in part because many of the devices have yet to be...

The Cascadia Initiative: A Sea Change In Seismological Studies of Subduction Zones

Creator:: Toomey, Douglas R., Allen, Richard M., Barclay, Andrew H., Dziak, Robert P., Tréhu, Anne M., Bell, Samuel W., Bromirski, Peter D., Carlson, Richard L., Chen, Xiaowei, Collins, John A., Evers, Brent, Forsyth, Donald W., Gerstoft, Peter, Hooft, Emilie E. E., Livelybrooks, Dean, Lodewyk, Jessica A., Luther, Douglass S., McGuire, Jeffrey J., Schwartz, Susan Y., Tolstoy, Maya, Weirathmueller, Michelle, and Wilcock, William S. D.
Abstract:: Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore/offshore seismic and geodetic experiment that takes advantage of an amphibious array to study questions ranging from megathrust earthquakes, to volcanic arc structure,...
