 Episodic tremor and slip

Episodic tremor and slip (ETS) is a phenomenon observed in subduction zones, particularly in regions where tectonic plates interact. It refers to a cyclical behavior of the crust that involves both low-frequency tremor and slow slip events on faults. ### Components of ETS: 1. **Tremor**: This involves the continuous release of low-frequency seismic waves. These tremors are not typically felt on the surface but can be detected by sensitive seismometers.
