the seattle rattle..


i have some important news for my friends up in the pacific northwest.. the next 2 weeks, you're on an 'earthquake watch'

live science is reporting that the chance of a major earthquake is 30 times more likely for the next two or so weeks..

from live science:

The slip began Sept. 3 on the Olympic Peninsula of Washington State and has migrated north to the Vancouver Island area, Cassidy wrote. Victoria moved 0.12 inches (3 millimeters) to the West over the course of two days. The events are thought to last six to 15 days.
Cassidy's colleague, Stephane Mazzotti, has done some calculations on the odds of a large temblor.
"The probability of occurrence of a megathrust earthquake is about 30 times higher during this approximately two-week window, than during the rest of the 14.5 month cycle," Cassidy told LiveScience. "Having said that, 30 times a small number is still a small number."
Geologists simply don't know when one of these events will trigger a major quake, Cassidy said.
The immediate importance of the event is that it occurred as predicted and can now be used to improve understanding of the region's seismology.
"By better understanding these events, we will be able to better predict the effects (and perhaps timing) of future magnitude 9 earthquakes along the West Coast," Cassidy and his colleague write.
A
separate study recently concluded that a major earthquake along the fault could be overdue, given clusters of the events seen in the geologic record. Because the fault is offshore, scientists say its rupture could create a devastating tsunami.
