Transients

Automated transient detection in Cascadia using RSI approach. (a) Tectonic settings of Cascadia subduction zone. Red dots: nonvolcanic tremors. Dashed line: isodepth contour of plate interface. Triangles: CGPS sites. (b) top-bottom: East component of displacement for station ALBH in N. Cascadia (see (a)), smoothed RSI and transient event probability, respectively. Source: (Crowell et al., 2016).

(a) Total surface displacements for 2014 November ETS event along the Cascadia subduction zone; (b) Accumulated transient slip from slip inversion. Red dots: tremor from PNSN catalog.
