Two end-member earthquake preparations illuminated by foreshock activity on a meter-scale laboratory fault

By tuning fault surface heterogeneity, the authors report earthquake preparation processes respectively driven by preslip and cascade-up on a meter-scale laboratory fault. The findings suggest that foreshock activity can be useful for predicting when and how the impending mainshock will occur.
