Algorithms for the Calculation of Exact Displacements, Strains, and Stresses for Triangular Dislocation Elements in a Uniform Elastic Half Space
Meade, Brendan J. (Elsevier, 2007)We present algorithms for analytically calculating the displacements, strains, and stresses associated with slip on a triangular dislocation element (TDE) in a homogeneous elastic half space. Following previous efforts, ... -
Andean Growth and the Deceleration of South American Subduction: Time Evolution of a Coupled Orogen-subduction System
Meade, Brendan J.; Conrad, Clinton P. (Elsevier, 2008)Present-day orography at the Andean margin is a result of isostasy, tectonic accretion, and erosional processes. The resulting excess mass of the Andes gives rise to frictional stresses on the seismogenic plate interface ... -
Block Modeling with Connected Fault-Network Geometries and a Linear Elastic Coupling Estimator in Spherical Coordinates
Meade, Brendan J.; Loveless, Jack (Seismological Society of America, 2009)Geodetic observations of interseismic deformation provide constraints on the partitioning of fault slip across plate boundary zones, the spatial distribution of both elastic and inelastic strain accumulation, and the ... -
Block Models of Crustal Motion in Southern California Constrained by GPS Measurements
Meade, Brendan J.; Hager, Bradford H. (American Geophysical Union, 2005)We estimate slip rates on major active faults in southern California using a block model constrained by Global Positioning System measurements of interseismic deformation. The block model includes the effects of block ... -
Controls on the Strength of Coupling Among Climate, Erosion, and Deformation in Two-sided, Frictional Orogenic Wedges at Steady State
Whipple, Kelin X.; Meade, Brendan J. (American Geophysical Union, 2004)Many important insights regarding the coupling among climate, erosion, and tectonics have come from numerical simulations using coupled tectonic and surface process models. However, analyses to date have left the strength ... -
The Current Distribution of Deformation in the Western Tien Shan from Block Models Constrained by Geodetic Data
Meade, Brendan J.; Hager, Bradford H. (Academy of Sciences of USSR, 2001)We interpret Global Positioning System measurements of interseismic deformation throughout the western Tien Shan in the context of a block model which accounts for important geologic features (faults) and physical processes ... -
Earthquake Cycle Deformation in the Tibetan Plateau with a Weak Mid-Crustal Layer
DeVries, Phoebe M. R.; Meade, Brendan J. (Wiley-Blackwell, 2013)Geodetic observations of interseismic deformation across the Tibetan plateau contain information about both tectonic and earthquake cycle processes. Time-variations in surface velocities between large earthquakes are ... -
Edge-Driven Mechanical Microplate Models of Strike-Slip Faulting in the Tibetan Plateau
Langstaff, Meredith A; Meade, Brendan J. (Wiley-Blackwell, 2013)The India-Asia collision zone accommodates the relative motion between India and Eurasia through both shortening and pervasive strike-slip faulting. To gain a mechanical understanding of how fault slip rates are driven ... -
Estimates of Seismic Potential in the Marmara Sea Region from Block Models of Secular Deformation Constrained by Global Positioning System Measurements
Meade, Brendan J.; Hager, Bradford H.; McClusky, Simon C.; Reilinger, Robert E.; Ergintav, Semih; Lenk, Onur; Barka, Aykut; Ozener, Haluk (Seismological Society of America (SSA), 2002)We model the geodetically observed secular velocity field in northwestern Turkey with a block model that accounts for recoverable elastic-strain accumulation. The block model allows us to estimate internally consistent ... -
From Decades to Epochs: Spanning the Gap between Geodesy and Structural Geology of Active Mountain Belts
Allmendinger, Richard W.; Loveless, Jack; Pritchard, Matthew E.; Meade, Brendan J. (Elsevier, 2009)Geodetic data from the Global Navigation Satellite System (GNSS), and from satellite interferometric radar (InSAR) are revolutionizing how we look at instantaneous tectonic deformation, but the significance for long-term ... -
Geodetic Constraints on San Francisco Bay Area Fault Slip Rates and Potential Seismogenic Asperities on the Partially Creeping Hayward Fault
Evans, Eileen Louise; Loveless, John P.; Meade, Brendan J. (Wiley-Blackwell, 2012)The Hayward fault in the San Francisco Bay Area (SFBA) is sometimes considered unusual among continental faults for exhibiting significant aseismic creep during the interseismic phase of the seismic cycle while also ... -
Geodetic Imaging of Coseismic Slip and Postseismic Afterslip: Sparsity Promoting Methods Applied to the Great Tohoku Earthquake
Evans, Eileen Louise; Meade, Brendan J. (Wiley-Blackwell, 2012)Geodetic observations of surface displacements during and following earthquakes such as the March 11, 2011 great Tohoku earthquake can be used to constrain the spatial extent of coseismic slip and postseismic afterslip, ... -
Geodetic Imaging of Fault System Activity
Evans, Eileen Louise (2014-06-06)Geodetic observations provide kinematic constraints on the behavior of tectonically active fault systems. Estimates of earthquake cycle activity derived from these constraints may depend on modeling assumptions and/or ... -
Geodetic Imaging of Plate Motions, Slip Rates, and Partitioning of Deformation in Japan
Loveless, Jack; Meade, Brendan J. (American Geophysical Union, 2010)Interseismic deformation in Japan results from the combined effects of tectonic processes including rotation of crustal blocks and the earthquake cycle process of elastic strain accumulation about upper plate faults and ... -
Geodetically constrained models of viscoelastic stress transfer and earthquake triggering along the North Anatolian fault
DeVries, Phoebe Maher; Krastev, Plamen; Meade, Brendan J. (Wiley-Blackwell, 2016)Over the past 80 years, 8 MW > 6.7 strike-slip earthquakes west of 40° longitude have ruptured the North Anatolian fault (NAF) from east to west. The series began with the 1939 Erzincan earthquake in eastern Turkey, and ... -
Imprints of Geodynamic Processes on the Paleoclimate Record
Austermann, Jacqueline (2016-05-18)In this thesis I investigate how solid Earth deformation associated with glacial isostatic adjustment and mantle convection impacted ice age climate. In particular, I discard approximations that treat the Earth's internal ... -
Inference of Multiple Earthquake-Cycle Relaxation Timescales from Irregular Geodetic Sampling of Interseismic Deformation
Meade, Brendan J.; Klinger, Yann; Hetland, Eric A. (Seismological Society of America (SSA), 2013)Characterizing surface deformation throughout a full earthquake cycle is a challenge due to the lack of high‐resolution geodetic observations of duration comparable to that of characteristic earthquake recurrence intervals ... -
