AbstractOver the past two decades, the discovery of a broad spectrum of fault slip speeds in subduction zones – from slow tectonic rate creep to episodic tremor and slip to fast earthquakes - has ignited a burgeoning new research direction focused on understanding the physical mechanisms that cause faults to slip fast or slow, and how slower slip might potentially interact with large destructive earthquakes and tsunamis. Advancing our knowledge of subduction fault and earthquake mechanics requires a qua
