It is during this time of contraction or ebb, tectonic plates and fault-lines have the greatest potential to shift causing earthquakes, and can activate volcanoes. If energy has been released by a series of small quakes or by one or more moderate to large quakes, the prospect of a mega-quake is greatly reduced.

When viewing the map below, notice the areas marked in red which show significant earthquake activity has occurred. Then notice the area marked in blue showing almost no activity. This is the area which would be at highest risk. The region marked in blue happens to be the Cascadia Subduction Zone.
See Article:The Great Danger of the Pacific Northwest.
Since an accepted method of earthquake predictability has yet been accomplished, all we can do is wait and see. However, it is always a good idea to have a 7-21 day preparedness packaging. I would also suggest there are periods of higher risk than others are.
