Medford, Ore. -- After California was struck with a 6.0 magnitude earthquake, the largest to strike since 1989, many wondered it is any indication that the "Big One" in Northwest is about to erupt?
According to Geologist Charles Lane the answer is likely not.
Napa's earthquake is on fault line associated with the San Andreas fault.
That works different than the the Cascadia Fault Line off the Oregon coast.
Scientists predict the Cascadia could break at any point, which could potentially be devastating to the northwest.
"Once you get north of Cape Mendocino, the entire tectonic scenario or situation changes. And instead of those deck of cards sliding by each other, now you get this convergence where they are butting head on together," Lane explained.
The last major quake on the Cascadia Fault hit in January of 1700 at a magnitude of around 9.0.
