Not All Heterogeneity Is Equal: Length Scale of Frictional Property Variation as a Control on Subduction Megathrust Sliding Behavior
GEOPHYSICAL RESEARCH LETTERS
25 april 2025
Rob M. Skarbek, Demian M. Saffer, Heather M. Savag...
Heterogeneity in geometry, stress, and material properties is widely invoked to explain the observed spectrum of slow earthquake phenomena. However...
