Descr: An integrated field experiment is undertaken in the Cascadia subduction zone to elucidate the relationship between water transport, aseismic slip, episodic tremor, and arc magmatism. The basic experiment has two field components: a broadband imaging array of flexible-array instruments integrated with Bigfoot and three small-aperture seismic arrays near sources of non-volcanic tremor. All will operate in the southern Puget Sound region for up to two years to sample teleseismic arrivals and at least two expected ETS events.
