Aftershocks Follow Slip Heterogeneity

The claim

Aftershock decay constants correlate with the heterogeneity of mainshock slip rather than with mainshock magnitude.

01Mechanism

Rough slip leaves unequilibrated stress patches that relax over time; heterogeneity sets how much remains.

02Prediction

Decay should track slip roughness.

03Refutation

Decay tracking magnitude would remove heterogeneity.
