SEATTLE ? At the Seismology Lab at the University of Washington, there is concern that the 7.7 magnitude earthquake that occurred on the British Columbia coast over the weekend could affect Washington.
?Earthquakes trigger more earthquakes," said Washington State seismologist John Vidale, who has long studied how different fault zones in Southern California affect each other, and is looking at the potential for the same effects here.
?We need to watch the whole region with extra care,? said Vidale.

Release the pressure in a major way along one fault, and it can then add to the pressure on another fault. As of early Monday afternoon, more than 130 aftershocks were recorded, including one more than 100 miles south of the quake?s epicenter, thought to be on the Cascadia Subduction zone.
The subduction zone threatens a much larger quake of approximately a magnitude 9 from the northern tip of Vancouver Island to Cape Mendicino California. The Haida Gwaii quake is not located along a subduction zone.
