A tsunami warning was initially issued, then canceled when a tsunami didn't materialize.

Aftershocks in the 5 range. Still moderate sized earthquakes in their own right.

Videos on the internet of rooms shaking and people hiding under desks. Lots of damage to roads broken by what looks like land slippage. Traffic in and out of Anchorage all snarled up.

No reports of any deaths or injuries at this time.

All in all, it sounds like things could have been a lot worse.

completely agree, however !
i suspect that because of the permafrost and lack of regular movement, there could be a significant amount of liquifaction that has yet to take place.
as things dry out and then after rain, it will rinse through.
additionaly more rain etc.

looking at the picture of the road that collapsed on top of a culvert

loose shale and historic erosion with new fill sitting on top

i would suggest caution around road dirt ramps and such like places where over the decades loose gravel and shale has been used as fill.

Ever the sensationalist alarmists, our local news mentioned that the earthquake that at any minute will rock the Pacific Northwest will be 30 times worse than this Alaska quake. I don't care. We live for today. And after tomorrow, we keep going. Que sera sera..

It's for real MR. The Pacific northwest is due for a giant earthquake. Your earthquakes are less frequent but bigger than our bay area ones. It's the same thing that makes the Cascade volcanoes. The Pacific plate is getting shoved under the North American plate, where it melts and some of the magma finds its way up to form the volcanoes. If the subduction process kind of jerks, all hell breaks loose earthquake-wise.

The same thing is happening up in Alaska. (And in BC, I'm guessing.) Alaska's got no end of volcanoes and it received a 9+ earthquake in the 1960's. It was the biggest in recorded US history. One of the biggest ever recorded. Luckily it was centered out in the wilderness, yet something like 130 people died, mostly in the Anchorage area.

But "expected today", in geological time, could be generations from now. We humans are short-lived little things by the standards of the Earth.

That's how Portland is.

I don't lose sleep worrying about our coming "Big One" either. But it's coming all the same.

I saw an episode of S.W.A.T. last nite about an earthquake that hits L.A. It got me worrying again about the Big One destined to shake the entire Pacific Northwest from Vancouver BC to northern California. AS usual I ran over my drill---get underneath my dining room table until the madness stops, which they estimate to be about 4-6 minutes. The Oregon and Washington Pacific coastline will be lifted 6 feet! Wooden buildings bolted to their foundations, (in compliance with a 1974 building code) should be ok. My apt is one of those. The number of casualities/wounded expected for a 9.0 magnitude earthquake like this are expected to be in the tens of thousands, with 500,000 displaced from their homes. With the tsunami there will be many more. After the quake I figure I would move back to Texas with whatever I can fit inside my SUV since it would be a long time til water and sewage is restored to my dwelling.

In any case, I DID relieve myself of the horror of this inevitability when I learned the chances of this happening over the next 50 years is about 15-20 %. That's good news to me. I don't plan on being here much beyond 30 yrs, so short of moving from Portland my chances sound pretty good. Again...breathe MR breathe...The end is not here yet. Smile
