New paper in Natural Hazards

July 10, 2024 – 5:50 pm

Cooper, Audrey, Michele Cooke, Kota Takayama, Danielle Sumy and Sara McBride, From alert to action: earthquake early warning and deaf communities, Natural Hazards, (2024). https://doi.org/10.1007/s11069-024-06719-6

literature maps shows three distinct custers of papers. 1) DHH+ experiences with disasters, 2) social vulnerability and 3) earthquake early warning. While some DHH+ and EEW papers cite social vulnerability papers, no papers from either DHH or EEW cite papers in the other cluster.

New paper in Tectonics the on early evolution of restraining bends in the eastern california shear zone

June 21, 2024 – 8:18 pm

each of seven different configurations of faults results in different uplift patterns. dipping faults produce greater uplift

Garvue, Max M,. James A. Spotila, Michele L. Cooke and Elizabeth R. Curtiss, 2024, What Controls Early Restraining Bend Growth? Structural, Morphometric, and Numerical Modeling Analyses From the Eastern California Shear Zone, Tectonics, https://doi.org/10.1029/2023TC008148

Max did a great job combining careful field data and numerical models to decipher the relationships between fault configuration and uplift patterns.

New paper on inverting for slip rate using GPS and focal mechanism data

January 28, 2024 – 11:23 pm

Hanna Elston’s new paper “A New Method to Invert for Interseismic Deep Slip Along Closely Spaced Faults Using Surface Velocities and Subsurface Stressing-Rate Tensors” is out in Earth and Space Sciences

Locations of regularly spaced (a) surface velocities (triangles) and (b) stressing-rate tensors (circles) for the complex fault model. Red fault trace indicates the inactive portion of the northern slip pathway in forward models. (a) Map view with black box indicating the region used for misfit calculations. (b) Oblique view of San Andreas fault system and San Jacinto fault system geometry colored by the forward model slip rates.

New Paper in Geosphere

September 24, 2022 – 2:21 pm

The paper shows the connectivity of faults and the directivity of rupture control whether earthquakes can pass through the San Gorgonio Pass.

Tarnowski, Jennifer, Christodoulos Kyriakopoulos, David. D. Oglesby,Michele L. Cooke, and Aviel Stern, 2022. The effects of pre-stress assumptions on dynamic rupture with complex fault geometry in the San Gorgonio Pass, CA region, Geosphere. https://doi.org/10.1130/GES02511.1

Initial magnitudes of shear (A) and normal (B) traction vectors for the regional stress models. GH, ESG, WSG, and SB indicate the Garnet Hill, eastern and western San Gorgonio Pass, and San Bernardino fault segments, respectively. Darker blue colors indicate lower stress, and red colors indicate relatively higher stress.

New Frontiers paper on coalescence of microcracks using work optimization

April 26, 2022 – 7:50 pm

Fattaruso, Laura, Michele L. Cooke, Jessica McBeck, 2022. The influence of fracture growth and coalescence on the energy budget leading to failure, Frontiers in Earth Science, doi.org/10.3389/feart.2022.853030

image of 8 plots. the left column shows the stress around the pre-cut faults. The right 6 show the opening and sliding on microcracks with fault evolution.

This plot shows the partitioning of energy between frictional work and internal work for both homogeneous and heterogeneous (with microcrack) models. The heterogeneous model requires greater energy to fail.

My Frontiers in Earth Science paper written with @geomechCooke and Jess McBeck is up! Here's the (open access) link. We investigated how fracture growth in rocks is affected by natural variation of weaknesses, like grain boundaries.https://t.co/aHCyzkCodR pic.twitter.com/tufI5L1lov

New paper on long-term slip rate variability

February 17, 2022 – 10:08 pm

Should we expect site slip rates around restraining bends to remain constant over the 10-100k time scales? Probably not ’cause sites migrate and fault systems evolve! Hanna Elston led this new paper out in Geology.

Strain map on the top and slip rate at sites indicted with colored boxes.
