Here is the seismograph on a nearby station::

t looks like 2 quakes, the first and smaller a minute earlier.

Since the collapse happened the media has had on all sorts of folks (lots of union people with a grudge) saying it wasn’t an earthquake. And, some scientists at a Utah university are saying it wasn’t.

There’s also a mindset with many that coal mining is evil, so you have some that want to believe the worst.

I don’t know, I don’t think anyone does at this time, what caused the collapse, despite the theories being thrown around. I feel the mine owner was going to be portrayed as evil no matter what. I feel really bad for him, he is distraught. But from I understand the mine operation was approved by the fed agency responsible for overseeing operations.

The location of the quake being shown near a place called “Minersville.” How ironic.

And what a strange place for a quake, and very shallow too. I wonder if there’s a mine nearby (ya think? I mean, it’s called Minersville...) I think there was another quake about this size near this location (Nevada/Utah border) a couple of weeks ago...

[muawiyah]

Some group called National Mine Safety Administration ~ believe that's correct ~ was directing the rescue.

They do that stuff.

[varina davis]

You are correct. The rescue operation was also approved by the safety feds.

It seems whenever a tragedy occurs, everyone want someone to blame. In this case, it’s Murray.

I am not at all sure it wasn’t an earthquake originally.

In any case, mining was, is and will alway be a dangerous profession. I doubt there are any guarantees for the safety of miners.

[muawiyah]

The trick is that when you dig under a mountain it might "shift" and drop rocks on you.

That's not an earthquake ~ it just is.

[sodpoodle]

“”””It seems whenever a tragedy occurs, everyone want someone to blame. In this case, it’s Murray.”””

Murray is damned if he does (step up to the mike) and damned if he doesn’t (comment on loss of rescue workers)

The press is determined to interview everyone in Utah for their personal opinion of Bob Murray and why he is a nutcase. What kind of useless information is that? The man is a miner, has coal dust on his face, has stayed on site for the whole rescue effort. He is having to deal with the biased media questions, the care of family members, while the fate of his six employees has been in jeopardy for over a week. IMHO the man shows more courage than anyone involved, with the exception of the rescue teams.

I have a friend who is a mining geologist in Utah with no affiliation with this disaster. He tells me that no mine accident EVER has produced a seismic event with a Richter reading over 2.0. He believes that the mine owner is blameless. He also noted that seismic activity on the entire Pacific rim has increased substantially in the last few weeks, so an event like this in Utah is likely coincident.

He also told me that the professor Fox as a consultant is using is a total jerk. I did note that he did falsely indicated that each Richter number ,as a factor of ten, therefore meant that a 4.0 was 30 times the magnitude of a 1.0, which is of course total bs. The Richter scale is logarithmic: i.e., a 4.0 event is a thousand times the energy of a 1.0.

With "expertise" like that, I would take what the mediots say with a bucket of rock salt.

[TMSuchman]

With all of the mining going on there is it possible that the mountian is falling in on itself, filling the void left behind with the coal be extracted.

Nature hates voids and does her best to fill it in with something....

[ghostrider]

I hope you are the only idiot who thinks this.

I don't know if he is an idiot for asking a question, but your answer reveals a lot about you.

[ontap]

It seems odd that they were so fast to jump on this old man from the gitgo. The first question by the press were telling to me and then 10 days after the event what do we get , a seismic event.

[libbylu]

I agree with you. Also they were consulting with mining experts from all over and are planning on bringing them on site. It is human nature to try to make the mine owners evil. I feel for Murray, I don’t think he is a bad man, seemed to be a real mine.

[ItisaReligionofPeace]

Yes, it says that I think that someone who believes that there is a conspiracy by the US Government, thereby including the scientists at the USGS, is an unbelievably stupid person with an obvious lack of any sense of reality. I could care less what you think about what I wrote.

[ontap]

Have a nice day!!

[B4Ranch]

Most of the charts I have seen that are being used by the media do NOT have USGS logos.

If you think the US Government has ethics and or integrity, your brain is frozen.

[Carry_Okie]

See post 30 genius. It's not as closed a case as you think. The seismologists at University of Colorado have an entirely different take on this event.
