Dynamic Emergence of Plate Motions and Great Megathrust Earthquakes Across Length and Time Scales
SUBDUCTION TOP TO BOTTOM: CONVERGENT MARGIN PROCESSES TRENCH TO ARC (ALEUTIANS/ALASKA AND BEYOND) III POSTER
tectonophysics | 13 december 2024
Jiaqi Fang, Michael Gurnis, Nadia Lapusta
The slow motion of tectonic plates over thousands of kilometers is intermittently interrupted by great earthquakes with sudden slips localized near co...

Bayesian Inversion of Rate-and-State Parameters from Frictional Sliding Experiments on Quartz Gouge
CRUSTAL DEFORMATION AND HETEROGENEITY FROM LABORATORY EXPERIMENTS TO LARGE EARTHQUAKE CYCLES III ORAL
mineral and rock physics | 12 december 2024
Taeho Kim, Nadia Lapusta, Dan Faulkner, John D. Be...
Despite the ubiquity of fine granular gouge in fault cores, small grain sizes are often avoided in experiments due to their propensity for unstable fr...

Scaling of Episodic Slow-Slip Events Simulated on Rate-and-State Faults: Effects of data processing and physical parameters
SLOW-TO-FAST EARTHQUAKES FROM SHALLOW TO DEEP: MULTISCALE RHEOLOGY OF PLATE BOUNDARY FAULTS IV ORAL
seismology | 12 december 2024
Auden Reid-McLaughlin, Nadia Lapusta, Luca Dal Zil...
Slow-slip events (SSEs) release significant tectonic strain through aseismic slip and are observed at nearly every subduction zone across the globe. T...

Effects of Bulk Poroelasticity on Repeating Earthquakes: Implications from Numerical Modeling
THMC PROCESSES IN SEISMOGENESIS ELIGHTNING
seismology | 11 december 2024
Linxuan Li, Nadia Lapusta
Most earthquake source studies ignore poroelastic effects activated by fault slip, in which bulk pore-fluid pressure (PFP) evolves due to shear-induce...

Experimentally deciphering shallow slow slip events along Nankai Trough-like subduction zones for realistic in-situ conditions and slip velocities
SHALLOW FAULT ZONE DEFORMATION OVER THE EARTHQUAKE CYCLE: OBSERVATIONS, EXPERIMENTS, AND MODELS I POSTER
tectonophysics | 11 december 2024
Piercarlo Giacomel, Dan Faulkner, Nadia Lapusta, J...
Episodic slow-slip events (SSEs) commonly occur and have been most notably recognized along subductions zones. Several mechanisms have been hypothesiz...

Slide-modified-hold friction tests: a promising tool for better constraining the state evolution laws in the framework of rate-and-state friction
MECHANISMS OF PROGRESSIVE ROCK FAILURE AND FRICTION ACROSS TIME AND SPACE II POSTER
mineral and rock physics | 10 december 2024
Piercarlo Giacomel, Dan Faulkner, Nadia Lapusta
Understanding and modeling fault stability, earthquake nucleation, and other features of earthquake source rely on the accurate determination of rate-...

Supershear transition on 3D faults with favorable heterogeneity
ASYNCHRONOUS ONLINE POSTER PRESENTATIONS: TECTONOPHYSICS
tectonophysics | 09 december 2024
Mary Agajanian, Nadia Lapusta
Supershear ruptures are characterized by propagation speeds which exceed the shear wave speed of the surrounding bulk. These ruptures have a character...
