Whats going on at yellowstone?

That last one has been rated a 3.7

Biggest one for a long time at Yellowstone.

Edit - it has been downgraded to a 0.8 which seems a little odd

Hmmm, they've up magnitude to 3.7!! That's quite a biggie for the area, isn't it?

So that's a 2.5, 2.7 and then a 3.7

I personally think it will be downgraded to something sensibly smaller, but lets see how things will evolve.

EDIT: we're seeing a YVO "trick": they've toned it down to M0.7 (EDIT: now M0.8) so that it will disappear from the USGS list until they figure out what's its correct magnitude.

Clever 'trick'.

The quake still appears on the utah.edu site. Link here

Yep, but as pic shows above - it now reads 0.8...

Is it common practice to change such data prior to confirmation?

It clearly posted as 3.7:

I noticed that quick downgrade myself, I think they know too many people are aware of these quakes and they wish to hide the doom potential. Consider, my friends, they do have a depopulation scheme to fulfill, even if nature helps them along. So it would do them no good for people to be warned and leave the area. The max number of casualties is what counts for them.

You know, I think I have become cynical. Dang it.

Seismos just showed another one - guessing 2.3...

yes, it's common for them to change their readings

So quickly?

Why?

I like this Alert Map a lot - it tells you everything! hisz.rsoe.hu...

Indeed, Yellowstone is rockin & rollin today

Everyone makes mistakes! From that one I would suspect it was a typo... but who knows what caused the glitch. I don't hold much truck with the conspiracy ideas of covering up quakes I'm afraid.

You mean to tell me that someone manually keys in the data at USGS????

Seriously?

No way! Really???

That can't be true.

The reason for the downgrade was probably that the method used to determine automatically the earthquake magnitude got fooled by the smaller earthquake occurred immediately next to the M2.8ish (in my opinion) one. Even I was able to tell that M3.7 was not the correct magnitude, but that's because I'm a human who can tell the difference with his eyes, not an algorithm.

But in such situations I'd expect the automatically generated earthquake report to be deleted, not reduced by human intervention to another clearly inappropriate value (note that the USGS world lists includes M2.5+ earthquakes, and the US list M1.0+ ones).

This is "damage control".

Yeah but they are a little slow and not final data.

Yeah it is crazy, last year they made all sorts of "adjustments" after the fact. had everyone all freaked out.

They do monitor, yes, and I suspect it was a mixture of human intervention after a tech/interference problem causing the reading.

But yes, readings do go up and down sometimes as reassessed etc. The fact that there are so many people tracking Yellowstone right now means it was picked up on quicker than they could amend it - most amends probably go unseen (unless you're a constant refresher/equake monitor like me )

I like the graphics but it's a wee bit too slow to update...

I'm not sure what you are looking at, but does this match what you are saying?



Link.

In relationship to the others (the last blue line), it looks big enough to me to exceed a M0.8.

The last big one was slightly bigger than the previous ones, but it was definitely not M3.7. Such earthquake would generate seismic waves 10 times bigger than a M2.7 earthquake and look much larger than that in the YMR webicorder. The smaller one immediately following is also certainly bigger than M0.8.

The M0.8 value they used is totally arbitrary - put there until some seismologist will be available to properly review it.
