BRKG Idaho Earthquake

Carl2

Pass it forward...
Having spent 30 years living in the area near the Mendocino Triple Junction, we rode that one through fine here in Gem County. I always worry the shaker we feel is big and far away. We had no damage here 15 miles northwest of Boise. Our collie dog was scared. A friend who lives in central Idaho about 50 miles closer to the epicenter reported no damage.

That's already happening crazy locust invasion in east Africa can eat as much as 35000 people in a day.
2nd way on its way to new location

LOL - oh man I had to read this a couple of times. I briefly though you were saying that they were eating around 35000 PEOPLE a day.
My warped mind quickly thought "well, direct them to China to help get rid of all the bodies they have piling up over there from the WuFlu."

Luckily the epicenter was in the remote mountains at Challis, about 80 miles from Boise. Here in Eagle (Northwest Boise area), I heard a loud rumbling noise and then everything began to sway from side to side, the pendant lights swung, the floor felt like it was moving from side to side, and I could see the walls swaying. It was over nearly as quickly as I figured out what was happening, but the pendant lights kept swaying for several more minutes. As far as I can tell the house wasn't damaged, though some nearby neighbors said they have cracks in their walls now. Felt an aftershock a short while later, but didn't feel any more after that - so far.

Supposedly this sort of earthquake is unusual for Idaho because it wasn't the typical up & down type of quake but rather it was a fault line quake (the kind typical in California). Local geologists from Idaho Univ. are excited about it and are sending a team to the area to learn more about the fault and check the aftermath.

Neither here nor there.

After a quake that big you should be experiencing multiple aftershocks which tells me that this is a foreshock to a much, much, bigger quake.

No disrespect for you intended, but I sincerely hope that you are wrong! LOL

Let's see...
Disruptive weather patterns
Worldwide pandemic
Economic crash
Earthquake....
What's next - locusts???

Already happening in Africa, India, Pakistan, etc., it's only a matter of time before they wind up here.

It was felt all the way up here in the northern most part of Idaho. I was blissfully unaware, taking a nap at the time. Oddly, my husband felt a rumbling while driving home.

It’s almost as if this was the beginning of Judgements upon the Earth, huh?
nah, can’t be. That would be for the superstitious, right?

I wasnt making lite Packy, I promise, the SLC eq was only a 5.4 and it had a lot of aftershocks.

I wasn’t making light either, there should have been far more aftershocks! I still think this is a foreshock to a much bigger quake!

No, actually that’s very few compared to other large quakes.

I thought you were dismissing seventy aftershocks as not qualifying for "multiple aftershocks," whereas if I was at the epicenter that would probably seem like almost continuous rocking and rolling to me. As far as I know there have been at least four greater-than-4.0 events since the main event but nothing greater than 5.0. While all of that may well be foreshocks rather than aftershocks, I suspect the 6.5 was likely the main event in this particular grouping. That area has had quite a few individual earthquakes over the years and of course there's no reason there can't be future events (even big ones) there as well, but I don't know that central/western Idaho is particularly known for its huge earthquakes. Yellowstone (which also means eastern Idaho) yes, but central/western Idaho?

As a member posted earlier in this thread that lives not far from the epicenter this quake wasn't the typical up and down type quakes that are common to the area, this one was completely different in how it behaved. I'm going with this is a foreshock.

That fault line is in the Sawtooth Mountains... mount ranges do move and in a major way from time to time, look at Mt. Everest.

I think i'm the only person in idaho who didn't feel it. I was outside when it happened. When I came in it was all over the news.

The largest earthquake in Idaho's recorded history measured 6.9 magnitude (the 1983 Borah Peak event), so this 6.5 likely ranks in the top few for all of Idaho. The 6.9 event was in central Idaho and not all that far from this 6.5, so I was wrong and central/western Idaho does have a history of big earthquakes. It's also worth noting that the Craters of the Moon (a series of lava flows) is not far from Borah Peak. Note that the lava flows were practically yesterday in geologic terms -- from Wikipedia: "The 60 distinct solidified lava flows that form the Craters of the Moon Lava Field range in age from 15,000 to just 2,000 years."

The epicenter looks to be fairly close to Deadwood Reservoir. It came through the earthquake intact, and I hope it withstands any aftershocks. It is an old dam and the first in a chain of dams. . .
