High‐Frequency Ground Motions of Earthquakes Correlate With Fault Network Complexity
GEOPHYSICAL RESEARCH LETTERS
14 june 2024
Avigyan Chatterjee, Greg Hirth, Jaeseok Lee, Danie...
Understanding the generation of damaging, high‐frequency ground motions during earthquakes is essential both for fundamental science and for ...
Role of Crack Interaction on Shear Localization in Porous Granular Rocks Deformed in the Brittle and Ductile Fields
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
17 april 2024
Taka Kanaya, Greg Hirth
Crack interactions leading to shear localization were quantified using microstructural analysis for brittle faults and high‐temperature ducti...
Hematite Frictional Behavior and He Loss From Comminution During Deformation Experiments at Slow Slip Rates
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
12 march 2024
Alexandra DiMonte, Alexis K. Ault, Greg Hirth, Cam...
Deformation experiments on hematite characterize its slip‐rate dependent frictional properties and deformation mechanisms. These data inform ...
Correlation of textures and slip behavior of hematite in natural and experimental faults
ONLINE POSTER SESSION FOR TECTONOPHYSICS I
tectonophysics | 22 january 2024
Alexandra DiMonte, Alexis K. Ault, Greg Hirth, Cam...
Common secondary minerals such as hematite influence fault rheology, and its variable grain size and textures reflect its formation and deformation co...

Can Clay Minerals Record the Dates and Rates of Deformation During Earthquake Cycles?
RATES AND DATES OF LITHOSPHERIC PROCESSES II ORAL
tectonophysics | 15 december 2023
Lydia Bailey, Alexis K. Ault, Sidney R. Hemming, A...
Clay minerals are common constituents of fault damage and govern the frictional strength, slip stability, and permeability of fault zones. However, we...

Creep Experiments on Talc-Quartz Aggregates at Slow Slip Conditions
RUPTURE AND DEFORMATION PROCESSES, FROM SLOW TO FAST AND FROM MICRO TO MACRO III POSTER
mineral and rock physics | 15 december 2023
Hannah Shabtian, Cameron D. Meyers, Greg Hirth
Slow slip events are quasi-stable, aseismic displacements along the subduction interface. The mechanisms of slow slip are not well understood, partly ...

Experimental Constraints on the Rheology and Deformation Mechanisms of Monazite Aggregates
RATES AND DATES OF LITHOSPHERIC PROCESSES I POSTER
tectonophysics | 15 december 2023
Keren Levine, Cameron D. Meyers, Calvin Mako, Will...
Deformation experiments on monazite aggregates were performed to investigate the effects of deformation and recrystallization on the interpretation of...

Influence of Subducting Sediment Properties and Fluid Pressure on Seismic Activity along the Subduction Zone Interface
SUBDUCTION TOP TO BOTTOM (ST2B): THE NATURE OF THE SUBDUCTION INTERFACE, EARTHQUAKES, AND THE ROLES OF FLUIDS II POSTER
tectonophysics | 14 december 2023
JiaXun Lin, Jiaqi Fang, Wei Mao, Emma Armstrong, Z...
Seismicity in different subduction zones exhibits significant variation in the spatial, temporal, and size distribution of earthquakes. The frequency ...
