Permeability-controlled migration of induced seismicity to deeper depths near Venus in North Texas

open access: yesScientific Reports, 2022
Migration of seismic events to deeper depths along basement faults over time has been observed in the wastewater injection sites, which can be correlated spatially and temporally to the propagation or retardation of pressure fronts and corresponding ...

Recurring Slow Slip Events and Earthquake Nucleation in the Source Region of the M 7 Ibaraki‐Oki Earthquakes Revealed by Earthquake Swarm and Foreshock Activity

open access: yesJournal of Geophysical Research - Solid Earth, 2018
Slow slip events (SSEs) on the plate interface are closely related to the occurrence of earthquakes and often trigger earthquake swarms in subduction zones.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

open access: yesThe FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

How frictional ruptures and earthquakes nucleate and evolve

open access: yesNature
Frictional motion is mediated by rapidly propagating ruptures that detach the ensemble of contacts forming the frictional interface between contacting bodies1-7. These ruptures are similar to shear cracks. When this process takes place in natural faults, these rapid ruptures are essentially earthquakes8,9. Although fracture mechanics describe the rapid

An organizational capability framework for earthquake recovery

open access: yes, 2017
Engineering and construction capability affects the cost and pace of post-disaster recovery. An organizational capability framework for effective earthquake recovery was developed after studying longitudinally 15 engineering and construction ...

FEM simulations of seismic cycle along a complex normal fault

open access: yesFrontiers in Earth Science
In the assessment and prediction of seismic hazards, developing numerical methods capable of accurately simulating long-term earthquake cycles in complex fault systems is of critical importance.

Effects of frictional properties of quartz and feldspar in the crust on the depth extent of the seismogenic zone

open access: yesProgress in Earth and Planetary Science, 2019
The depth extent of the crustal seismogenic zone is closely related to the size of earthquakes. The mechanisms that control the depth of the lower transition of the seismogenic zone are important issues in seismology and disaster mitigation.

Transformational Faulting: The Case of Quartz‐Coesite

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Transformational faulting in olivine has been widely invoked as a possible triggering mechanism for deep‐focus earthquakes, yet its dynamics remain debated. It is unclear whether it requires the combined effects of heat release, volume change and mechanical strength contrast, or whether it can be triggered by any one of these alone.

Stress transmission along mid-crustal faults highlighted by the 2021 Mw 6.5 San Juan (Argentina) earthquake

open access: yesScientific Reports, 2022
Understanding the mechanisms of crustal deformation along convergent margins is critical to identifying seismogenic structures and assessing earthquake hazards for nearby urban centers. In the southern central Andes (28–33 $$^{\circ }$$ ∘ S), differences

Earthquake nucleation on faults with nonconstant normal stress [PDF]

open access: yesJournal of Geophysical Research, 2011
[1] Previous studies have found that earthquake nucleation on faults with rate-and-state dependent constitutive properties is a time dependent process involving evolution of slip rate v and frictional state variable θ. The evolution of θ is governed by an extended aging law, which accounts for the effects of normal stress variations.
