So why post a little 1.5? Just so happens this just occurred in Clintonville, WI where there have been loud booming sounds for the last three nights. Sorry if I messed up the format, first post to this thread.

Clarification: Although this was just posted to USGS, it occurred a couple days ago (Tuesday) just after midnight. Sorry for the confusion.

As I have been perusing this thread all day off and on, I saw that these mysterious subsurface booms are manifesting far beyond Wisconsin. Right on time with the 188th day theorum. Well, otherwise, I'm getting majorly creeped out. It means something. But what? And it can't be good.

when I clicked the usgs link it doesn't say clintonville, do you think they removed it?

also I too am getting a little creeped out over this now.

Introductions ATS, I've been lurking here for a while, quietly learning about these earthquakes and their patterns, and I am impressed with the dedication that some of you have shown to this thread. I was just on the Global incident quake map and saw a 3.1 tremor in Wyoming and my heart just about jumped outta my chest! I know this isn't a big one but I've not seen a whole lot of activity there in the past couple of years. I really hope the sleeping giant isn't stirring at yellowstone. Any body else see this? Thoughts? Just noticed that the usgs site doesn't list the 3.1 at all, yet the globalincident quake map shows it coming from the USGS feed... WTH?

I know most of you have rummaged through multiple news stories pertaining to these unexplained booms in the land of the cheese heads. I also know that it did not escape most of us that the USGS insisted that there was NO seismic activity in the area in question.

And then presto.......all of the sudden they thought they would just throw a 1.5 for good measure.

I do not want to sound like a conspiracy nutter, but what the #@$% is going on up there at that chicken $#!^ outfit.......man..... the way our institutions of Gov't treat the people of America, just plain pisses me off

There is always a possibility of a bigger quake, but so far this seems like a classic Mag 7 and aftershocks. There should be a Mag 6 within the next 6 months, but I doubt most people will remember it being part of the aftershock sequence if it longer than a couple of months from now.

note I said "so far". That was early on, and I was covering my ass
In fact it pans out that it doesn't look like a classic 7 aftershock sequence at all.
Heres a graph for the first 53 hours (based on SSN data, USGS are useless below 4.6 for Mexico)
* also note SSN have downgraded their mainshock from 7.8 to 7.4


and here's the ones I'm comparing it to, that I did before

Still 19 hours to go to the 72hr timeline I use but it doesn't quite look like the other quakes.
I'm wondering if its due to the larger size of the main shock.
Its hard to get decent aftershock lists of land based quakes of the Mag 7 range, as most 7's either happen offshore or if they are on land its somewhere they don't have a very good seismic monitoring network, like the Gobi Desert.
SNN is not a bad organisation, but I wonder if they have missed or been unable to ID some of the Mag 4's, there seems to be a low number of mag 4 aftershocks.
I'll finish the graph when the 72 hrs are up and add it to the World 7+ project 2012 page

a bit more to post by muzzy


Not a lot to compare with locally, the SSN data only goes back to 2006 and the only big quake during that time in Oaxaca was this one, which ANSS called a 6.3Mw (its also shown on the Oaxaca eq history map a page back)

Inconclusive, not many 4's above 4.2, no aftershock with a reading one less than the main shock (in this case no mag 5).
Not much to go on, but I didn't go beyond 72 hours, and I didn't cross the border to Guerrero either.

No mention of Clintonville in the current listing.

The coordinates have not been changed from the listing posted by AnonymousCitizen; all you missed were the 'ex' tags to denote offsite content, but this is a prime example of a low magnitude quake that is of interest due to the other activity around the noises.

If you plunk those numbers in to google maps or google earth, it shows up right smack dab in the middle of Clintonville (105 Main Street in google maps), so I don't know why that would have been removed from the listing. Oddness

Can anyone cross-reference the time and location of the quake with the booms? I'm on my son's iPhone (been having bad luck technology-wise with my gadgets, so I am handicapped resource-wise) to see if there is any correlation?



Edit to add:

I am very glad you caught the original listing that shwwd Clintonville as the epicenter and I also want to say that I've always loved your avatar, AnonymousCitizen!

For some reason that just cracks me up...

same magnitude as the newcastle earthquake back in 1989. from the looks of it this is pretty much well into the outback. so no major structures or city populations out that way. bet it scared the bejeezers out of the kangaroos though..lol

jeez...just remembered seeing that video on ats last week that showed the lines or something across the world of the next predicted quakes and i had a slight chuckle as a line ran directely through australia from the top end down to south australia. i have just looked at the location of this quake and i will be buggered if its not exactly where that line went.

My aunty lives in Alice springs. Ill have to contact her soon. Isnt it very rear to get quakes in central Aussie. Are there major faultlines around that area?

reply to post by aarys


i reckon she could have felt it in alice springs as the it would be the biggest near township probably from the epicentre. its very rare, that rare in fact that i need to check out the fault lines and do some research.
