Listening to Crandall Canyon mine owner Robert Murray on TV the other day, I heard him but saw only rainbows, twinkling stars and happy children playing outside in the middle of January. Here was the operator of a notorious facility in a notorious industry not pulling the community together and giving us the truth about what really caused the collapse that’s trapped the six miners near Huntington, but covering his own smouldering behind and using the free air time to bad mouth reporters, environmentalists, the Democrat Congress, renewable energy advocates and- perhaps most shocking of all- seismologists (how can you knock a seismologist, Bob?).
Murray probably stands to lose billions if insurance doesn’t cover the disaster because it wasn’t an earthquake, as he insists but the evidence refutes, or other act of Nature. Despite the evidence, Murray denies his workers were engaging in “retreat mining,” the controversial and dangerous practice of closing a shaft by knocking down the coal pillars supporting its ceiling, even though his company asked for and got permission to do so in 2005. Murray’s unapologetically torqued his employees and their families, the news media, the Hispanic community and- perhaps most shocking of all- seismologists (they seem like such nice people).

he University of California at Berkeley tonight confirms what seismologists have said from the beginning: The collapse inside the Crandall Canyon Mine was not caused by an earthquake.
As we reported Monday, seismograph waveforms have fingerprints, if you will, often showing the source of ground shaking.
That report, released tonight by the University of California, confirms what the University of Utah identified on Monday -- seismic waves recorded on instruments came from an underground collapse, not an earthquake.
Scientists say the disagreement between them and the owner of the mine over the past three days has been unfortunate.
James Pechmann, with University of Utah Seismograph Stations, says, "He's not a seismologist. I think his interpretation of our data needs to take that into account."
Scientists say seismicity in the mine most likely is coming from additional movement or failures, again not from an earthquake but from the aftermath of the collapse itself.
