Cascadia subduction zone: two 6.6+ quakes within minutes off Vancouver Island.

[catbyte]

Cascadia makes me nervous. It's the only sector of the Pacific Ring of Fire that hasn't produced a megaquake this century. I know a full rip of the fault may be hundreds of years away, but it could happen tomorrow. I hope all DUers in the Pacific northwest have disaster plans in place. Precautions are the cheapest things you can invest in.

1. Thanks for the report!

Those were deep enough not to pose much of a tsunami threat, I think.

2. didn't feel a thing in seattle.

5. Me, neither...

Sure makes me nervous.

However, if these release some of the stress, perhaps it staves off the "big one" for a while longer.

ps: I'm a few miles south of Seattle.

3. Wow. I use the Earthquake 3D app

and it says 6.8, 4.4, 4.3, 4.9, 6.6, 6.8 all near Port Hardy Canada so far this morning. Those are nothing to sneeze at. 😳

4. Thanks for the reminder to complete disaster preparedness kit. Will do.

6. Get 3 days of supplies first

Of food, medicine and water. First steps are often the hardest. Then build to 7 days. We are at almost at a month. 2 bottles of Jack too

Did not feel it in Portland today. Too true about the Pacific Rim of fire. The night they stole the elections I had 2 thoughts; what regressive world will my daughter be in and when the big one hit the Pacific NW, FEMA will be politicized by how much love we show to The Baby King.

In other words, assuming no help for a while.

7. Subduction zone earthquakes in that region

always have me watching volcanoes in the region. They're related to the subduction zones.

8. Regular small quakes are good, tolerable energy release instead of storing it

Energy / friction builds constantly, better to have it released than stored
