Shear-wave-induced softening and simultaneous compaction in dense granular media through acoustic lubrication at flow heterogeneities
Charles K. C. Lieou, Jerome Laurent, Paul A. Johnson +1
We report the simultaneous softening and compaction of a confined dense granular pack in acoustic resonance experiments. Elastic softening is manifested by a reduction of the shear…

The temporal limits of predicting fault failure
Kun Wang, Christopher W. Johnson, Kane C. Bennett +1
Machine learning models using seismic emissions can predict instantaneous fault characteristics such as displacement in laboratory experiments and slow slip in Earth. Here, we addr…
