ETS, or 'episodic tremor and slip', is a recently discovered phenomenon in seismic research. Similar to earthquakes but much smaller in magnitude, ETS events are associated with the subduction zone of some convergent plate boundaries. One such region, the Cascadia subduction zone under the Puget Sound, is the focus of an experiment by Ken Creager's group at the University of Washington (UW), called Array of Arrays.

In July and August of 2009, seven scientists deployed several seismic sensors for a two-year multidisciplinary study of one of the world's most active volcanoes, the Sierra Negra Volcano of the Galápagos Islands. The project's official name is “Collaborative Research: An integrated seismic-geodetic study of active magmatic processes at Sierra Negra volcano, Galápagos Islands.”
