Yellowstone Quake Swarm Ongoing- Produces M4.5 Quake

Nope, looks like Norris area is not dead yet. Just had another estimated 1.6 to 1.9 hit in that swarm area to the west of Norris. Good luck on getting the USGS or UU to post THAT on a holiday. But no worries, we got this.

And, just when I thought it was nearly over, an abrupt increase and flurry of events just occurred in the main swarm area, starting with about an estimated 2.2 to 2.5 quake, and then followed by a bunch of smaller ones. Maybe this was its last hurrah, dunno. Seems to be tapering off again now, we'll see.

Well I just woke up to someone saying there was a 5.8 up near Great Falls, Mt. That's quite a bit away from these current swarms, but close enough to make me wonder about correlation....actually she posted there were 9 total, 3 of which she felt.

After consulting the map, I see there were a total of 16 up there, and a 2.5 down in the swarm area by Yellowstone.

TA has an ongoing thread about the event HERE.

Cheers

Latest Update:
Well the swarm has calmed down to pretty much nothing for the last day or two. At present, it has been many hours since even the smallest event has happened, so it might be over. It MIGHT.

I guess nature was considering putting on the most impressive 4th July fireworks display in history....

a reply to: TrueAmerican My daughter posted on F.B. and she called out as fake, a Yellowstone Geyser, with molten lava spitting out. Some of this click bait B.S. isn't helping us determine what the real quakes are doing in N.W. Montana. My son was still up in Lewiston, Idaho, on the Wash. State border, and he felt the sofa under him start to "buzz". Some photo frames hanging on his wall, also started banging back and forth.

Lewiston is pretty much West of Missoula, Mt. and the 5.8 quake is pretty much East of Missoula. So this shaker propagated pretty far to the West, from it's epicenter. Lewiston is still on top of the massive granites of the North American Plate. Not too far to the West, in Washington State, the Granite breaks away to Lord knows what. There's a mile deep puddle of solidified basalt members, on top of the basement rocks.

Haystack Rock on the Oregon coastline, flowed from the Kamiah Basalts off to the East of Lewiston. At that time in Geologic History, ( Miocene ), things were extremely flat, all the way to the Pacific Ocean. The Cascades weren't even beginning to uplift, then.

This latest quake was only part of the continental divide's normal creaking. I doubt that it's connected to the Yellowstone Plateau, except that near Craig Pass, the Continental Divide runs through, near here.

a reply to: carpooler

Yeah, I have no idea why people gotta post totally BS stories like that, of that "lava geyser." Click factor high is all. They ought to nail him for inciting public unrest based upon falsified information. *shakes head*

Latest Update on swarm:
We've had another estimated 2.5 or so, plus several smaller quakes today at YS. USGS/UU has not posted it yet- it's Saturday. So it looks like it can still pack a punch, or is potentially prone to cranking up again. Anyone who would like to monitor the park live can join our live stream of live seismos here:

I'm just going to plant this here to see if anyone sees what I see.


I still think that little landslide in the Bighorns that made national doom news awhile back was caused by the floor of the Bighorn Basin sinking a bit.

I think I see where you're going with this; could be, I'd like to see a recent InSAR image of the area in the map.

a reply to: jadedANDcynical

Thanks for the reply, Jaded!
Yeah, I need to put more time into it.
The whole outlined area is ringed with hot springs, I could spend a year placemarking them.

To Add: If I could find an inSAR animation like JPL did for Etna, that would just be peachy.

Hey guys, thought you might like to see this.
Hope this doesn't raise too much of a stir, but it sure raised an eyebrow here.
In the EQ feed, I was talking with TA about the area here and mentioned Thermopolis, WY.
It's in Hot Springs County and is home to the World's largest mineral hot springs.
Just North of Thermopolis , is the town of Worland.
A couple days ago, there were reports of a sulfur fire burning there.
Hearing a bit more on the news this morning, apparently is was started by a motorcycle exhaust spark.
I originally thought that maybe it was at some kind of sulfur processing facility, but it sounds like it was just a concentration of it on the landscape that got ignited. Typing a quick post before heading out to work, but wanted to get this video up before I did.

Hi Sage.

I found an article refering to the video.

It says "A sulfur mound left over from Gulf sulfur Plant."

Sounds like they knew what they were dealing with.

Thanks Kat, it was too late to edit the last post so I was just now going to put up the correction as I read a little closer.

There's definitely enough sulfur around to harvest it.
Apologize for the off-topic.
Being from the place and having traveled it extensively, I associate the Worland / Thermopolis area as being part of the beast - Or at least an extreme by-product.

boom boom boom
the swarm continues near Yellowstone
Montana takes a break and then Yellowstone wakes up
it's a call back
like birds calling to one another.
