Spatial Relationships Between Coseismic Slip, Aseismic Afterslip, and On‐Fault Aftershock Density in Continental Earthquakes
JOURNAL OF GEOPHYSICAL RESEARCH: SOLID EARTH
23 january 2024
Robert Churchill, Maximilian J. Werner, Juliet Big...
Damaging aftershock sequences often exhibit considerable spatio‐temporal complexity. The stress changes associated with coseismic slip and as...
Relative Afterslip Moment Does Not Correlate With Aftershock Productivity: Implications for the Relationship Between Afterslip and Aftershocks
GEOPHYSICAL RESEARCH LETTERS
22 december 2022
Robert Churchill, Maximilian J. Werner, Juliet Big...
Aseismic afterslip has been proposed to drive aftershock sequences. Both afterslip moment and aftershock number broadly increase with mainshock siz...
Non-linear viscous shear zones and a potential slow slip mechanism
COMPARATIVE INVESTIGATIONS OF SLOW-TO-FAST EARTHQUAKES: OBSERVATIONS, EXPERIMENTS, AND NUMERICAL MODELING V ORAL
tectonophysics | 15 december 2022
Lucy Lu, Ake Fagereng
Slow slip events (SSEs) are episodes of aseismic slip at rates of 0.1-1 m/year that are commonly temporally associated with tremors. SSEs have been ob...
