Records show that thousands of earthquakes have occurred in the northern Puget Lowland since 1969. At least fifteen of these events have been greater than magnitude 4, and one (Deming mag. 5.2, 1990) was the second largest recorded shallow crustal event in Washington for the last hundred years. Despite the evidence that suggests that the potential for great earthquakes capable of severe damage in the northern Puget Lowland is very real, the seismicity in the area is poorly understood. This is in part due to the wide scattering and apparently random assortment of recorded events. This thesis attempts to create …
