To fully understand the earthquake potential along the coastal United States, one must first understand the extremes before attempting to predict upcoming quakes.
Anyone can predict a quake in a highly active zone...they happen daily only the intensity is the variable. Most quakes, 3 and under are seldom felt and are quite common.
There is an area in California's coast known as the 'Lost Coast' located in the southern portion of Humboldt County that has the highest number of recorded earthquakes.

Recent Earthquakes on California's North Coast
Updated January 23, 1997
California's North Coast, particularly in the vicinity of Cape Mendocino and the coastal and offshore areas of Humboldt County, is one of the most seismically active areas of the United States. About 25% of California's annual release of seismic energy comes in this region. Since 1980, there have been five earthquakes close to magnitude 7, and an additional 6 of magnitude 6 or larger. In the past 5 years, 7 earthquakes in the region have been strong enough to produce Modified Mercalli Intensities of VII or greater. The high rate of seismic activity in the region is related to the complex geologic setting resulting in a number of different sources of potentially damaging earthquakes. Recent earthquakes demonstrate both the high activity rate and the diversity.
Also the uppermost beginning of the San Andreas fault where it enters the mainland.
Also the location of the continental plates.
Also the most westerly portion extension of U. S. land along the Pacific Ocean.
Also has the highest rainfall in the United States recording 200 inches plus annually.
Also the least explored land in the U. S.
Also the most inaccessible land in the U. S.
