DLESE description of Animations of Episodic Tremor and Slip

This collection of animations shows episodic tremor and slip (slow earthquakes) from a subducting plate with locked, slow slip, and no slip zones. The first two show wood blocks being pulled over sandpaper to simulate buildup and release of strain in locked and slow slip zones of a subducting tectonic plate, and to simulate episodic movement of a subducting tectonic plate. Graphs display time versus strain or time versus distance for each of the blocks. The third animation shows a cross-section through a subducting plate illustrating the movements of a GPS station as subduction proceeds. Graphs show time versus distance under three scenarios: locked plates, slow slip, and no slip. The last animation shows horizontal movement of a GPS station as a graph displays time versus distance and a seismogram denotes shaking events.
