Yes, absolutely, it’s coming, however we can not currently predict earthquakes, so any claims to a timeframe are purely speculative.

Its is ok you will join the island of California.

Stolen from Wikipedia: "In the 1970s, scientists were optimistic that a practical method for predicting earthquakes would soon be found, but by the 1990s continuing failure led many to question whether it was even possible.[4] Demonstrably successful predictions of large earthquakes have not occurred and the few claims of success are controversial. For example, the most famous claim of a successful prediction is that alleged for the 1975 Haicheng earthquake.[5] A later study said that there was no valid short-term prediction.[6] Extensive searches have reported many possible earthquake precursors, but, so far, such precursors have not been reliably identified across significant spatial and temporal scales.[7] While part of the scientific community hold that, taking into account non-seismic precursors and given enough resources to study them extensively, prediction might be possible, most scientists are pessimistic and some maintain that earthquake prediction is inherently impossible.[8]" [en.wikipedia.org]

So to sum up, predicting when earthquakes will happen and how severe they will be is extremely difficult and perhaps even impossible (certainly impossible right now). What we can estimate, however, is the probability of a major earthquake happening in a given number of years - as a result of the Juan de Fuca plate, the North-West region is more likely than not to experience a major quake every 430 years. The last one was in 1700, so while there's a fairly high chance that another may occur in the next 130 years or so, saying so with certainty is impossible.
