Cascadia Subduction Zone

Hi All. While searching for some new information concerning the ECSZ I came across this. Take Care…Don in creepy town

The observed horizontal strain rates indicate that strain is accumulating everywhere along the CSZ from Cape Mendocino to the Strait of Juan de Fuca. These observations do not indicate whether the strain will ultimately be released by a single great M9 earthquake, by a sequence of smaller M8 earthquakes, or by some other scenario. However, we find no evidence that the megathrust is segmented by shallow regions where strain is not accumulating, so the hypothesis that the strain could be released by a single great earthquake cannot be rejected. Measurements by recent GPS surveys and permanent GPS stations installed since 1996 [e.g.,Khazaradze et al., 1999], should soon provide greater spatial resolution of deformation and strain accumulation along the CSZ.
