That was a good one!

6.4?

Can't believe it was only a 6.4, haven't had such a long ride since the Loma Prieta quake.

It says 7.1 across from Anchor point......woke me up here in Delta

We lost a picture off the wall and some knick knacks off a shelf. And of course got a screaming infant out of the deal. Roller coaster for sure

Shelf of reloading components collapsed, wide awake now!

7.1 is pretty major. Did you guys sleep through the after shock? 4.3? Hope all is well.

Felt that one real well here in Kenai. 7.1 is the official at this point. Looks like the eppi was under Pedro Bay.

Shook us awake. I'll bet it shook here close to 1 min.

Damaged K-beach road about 1 mile from Sterling HWY. 1+ lane closed.

7.1 initially, now I read a 6.79.

Not getting comm from several friends in Seward....power or cell tower problems?

The depth (76 miles) and location of this earthquake indicate that it occurred inside the subducting Pacific Plate rather than at the place interface. The rupture was caused by extension of the plate as it is pulled into the mantle by its own weight.

This is a common type of event for this region and depth. However, at magnitude 7.1 it is the largest intermediate-depth earthquake recorded beneath Cook Inlet since the regional seismic network was established in late 1960s. Earthquakes of similar sizes occurred in the Lower Cook Inlet in 1912 and 1933, but we do not have precise magnitudes and locations for that time period.

We recorded about 30 aftershocks in the first 2.5 hours after the earthquake. The largest was a magnitude 4.3 at 12:37 UTC (3:37 am local). Aftershocks are continuing at a steady rate and can be expected to go on for several months, although the rate of aftershocks should decrease considerably after a couple of weeks.

10K homes without power in SC.

It woke Etta and I out of a sound sleep here in Wasilla. No real damage other than one of her angel figurines lost a few body parts when it fell to the floor.

The wife rousted me outa bed, or would have slept through it! It sure had some hang time. Hope all is well on the KP Ironbeder, et al(that means and others )

Jeff

For non-Alaskans, what is "SC"?

South Central

Thanks, Jeff. Seems OK, very minor damage seen at the hacienda so far.

Some pics and video online (radiokenai.net and FB) of grocery store items on floor.

Good to hear!

Didn't wake me in North Pole.

Ironbender,

I have lots of friends in Kasilof (used to have a place there myself). Is that area without power now?

John

Not sure where power is out. The 10K number came from a news report.

K-Beach Rd is damaged at the Kasilof end.

Just talked with a buddy about 3 miles up the highway north of the K-Beach road and Sterling highway intersection and he has power.

Wasn't sure how to grab a screen shot, but the map at the bottom of the page shows the location for those not familiar with the area

ps

here's one

That's right In waterrats backyard. Hope he and Marlene are ok.

Fairbanks street lights swayed from that quaker, 29 gallon fish tank had a tsunami. Pretty good quaker that shimmies 400 miles away. (I'm sure I would have slept through but for our earthquake sensor, a cheap wood closet door, that started creaking for a good while before the shimmying hit.) Glad people closer seem to be okay.

Just walked through the door getting home from SHOT when it started. Knocked stuff around pretty good.

Offshore platform cook inlet - I know what the tip of a spinning rod feels like now. Cleared shelves and shut stuff down.

didn't feel a thing here in Pa. beagle is still asleep on the couch.

Interesting plot.



Earthquake cross section through the Cook Inlet region
Here is a cross section through the Cook Inlet region. The circles are historical earthquakes. Note that this morning’s earthquake occurred inside the Pacific Plate. This is a frequent source of earthquakes in the region. Its depth is very important because it demonstrates that the earthquake has nothing to do with processes in the crust including known faults, volcanoes, bodies of water, sedimentary basins---or any other type of local geology. This earthquake occurred in what was once (millions of years ago) the crust under the Pacific Ocean. As the Pacific Plate is pulled slowly into the earth (a couple inches per year), the stretching creates earthquake. The location, fault orientation, and slip of the M7.1 earthquake align perfectly with this stretching action.

Sadly, that may be the most excitement you get all year. We get told we are in the Ring of Fire regularly.

I'm going with the theory that "Alaskan Frackers Do It Deeper". That's my plot and I'm sticking to it.

We were rolling pretty good in the 4th floor of the Marriot anchorage last night. We spent 2 hours outside in the truck, waiting for the lobby to clear of folks and mgmt to give the all clear that gas lines were intact. That was one of two big ones I remember since I got here in 95. My lovely bride lived thru the Loma Prieta quake in 89, so keeping her calm was probably the most exciting part of the evening!

Can't have happened. The universe is 6,000 years old and was created as is, unchanging.

That's great! Where did you get this?

Really shows the subduction zone. Funny how this wasn't really known until plate tectonics theory in the 1960's!

Only criticism is the directions (NW-SE) should be reversed!

Cheers, Chris

Not sure why you think directions should be reversed. The pacific plate moves in a SE-->NW direction and is the plate being subducted.

Yeah yeah

Heard from our friend out on FRR, said it shook him awake and emptied some of his cupboards, gonna need some new wine glasses by the sounds of it. No structural damage.

Thank you Ironbender, that's just the geo in me with cross sections. Usually do x-sections south left to north right, west to east same. That one I would do SE to NW left to right. Mining engineers on the other hand often do them back to front.....

Thanks, Chris

Gotcha.

Because of the thrust direction, it's pretty much a straight cross section just not compass-aligned.

Hope all you folks are safe up there.

Missed me it did.….
