The next big one
Although the last giant earthquake hit Washington's coast 300 years ago, scientists say that the Cascadia Subduction Zone may be storing up energy to be released in the next catastrophic earthquake. The stresses detected off Washington's coast could generate a huge earthquake (magnitude 9 or more). That would rival the largest earthquake ever recorded. (A magnitude 8.7 earthquake would release 1,000 times the energy of the magnitude 6.6 earthquake that struck Los Angeles in 1994.)
When it hits
Violent shaking will last at least two minutes. The ocean floor will drop, most likely creating a tsunami that will strike long stretches of the coast. The central Olympic peninsula will suddenly rise, while some coastal areas will sink below sea level.
If an earthquake occurs at the coast
Drop, cover and hold. Get under a sturdy object and hold on. Watch for falling objects.
As soon as the shaking is over, move to high ground or inland. Do not wait for an official warning.
Stay away from the coast. Waves may continue to arrive for hours.
Listen to your local radio station for an official "All Clear" notice before returning to the coastal area.
Be alert for aftershocks.
Protect yourself and your family
Develop a family disaster plan. Everyone needs to know what to do on their own to protect themselves from an earthquake.
Be familiar with local Emergency Management earthquake and tsunami plans. Know where to go to survive a tsunami.
Be prepared to survive on your own for a minimum of three days.
Prepare a disaster supply kit for your home, automobile and work.
Take a first aid course and learn survival skills. Knowledge is your greatest defense against potential disaster.

Cascadia is truly bothering me. Very surprised that John has not said anything on the Port Hardy umm swarm? John does this have you Folks on edge also?

Any link between eclipses and earthquakes would be a great surprise to me. I don't see any reason for there to be a correlation.
Parts of the San Andreas Fault are so sensitive to stress that the faint gravitational tug of the sun and the moon may be enough to cause tiny tremors 15 miles underground, a team of UC Berkeley seismologists has found.
Ediz_Celik: Do solar eclipse affect earthquakes ?
Mitzi: There's no correlation between solar or lunar eclipses and increased earthquakes or increased storms.
Turkey's top seismologist explained to a nervous public yesterday that there is no link between eclipses and earthquakes and gave assurances that there is nothing to fear from a solar eclipse on March 29. "When we check to see whether there is a scientific or statistical model to link solar eclipses with earthquakes, we find none," Gulay Barbarasoglu, the head of the Istanbul's Kandilli observatory, said. "Right now, we unfortunately see a serious lack of knowledge and a serious mix-up of facts out there."
So how can any of you be certain that the alignment of the sun and moon, and the combined gravitational effect this alignement has on this planet’s floating crust, would not be enough added stress to trigger the release? Particularly when the alignment is precise enough to produce an eclipse?

would(to) be a great surprise to me.

Since about April 25th, there's been quite a few quakes around Northern Vancouver Island (that's where I live). Could it mean anything?
Experts say a "swarm" of small earthquakes off the northwest coast of Vancouver Island are part of the normal seismic activity in the area, and they could continue for several more days
Rogers said more small earthquakes are expected in the area over the next week.
"They often go on for days. There's been a lot of smaller ones, so eventually they'll wind down, but typically, what we've seen in the past is that most of these swarms last a few days to a week or so."
A similar but more powerful swarm that struck the same area in August 2008 included a magnitude 5.2 quake..
