Like Barnes, Fitch said the depth of Saturday's quake -- 5.9 kilometers below the Earth's surface -- is "key" to ruling out the possibility that the quake was induced by human activity.

Barnes said there's "no question" that seismic activity has been triggered elsewhere in the country by injecting wastewater at high pressure deep in the Earth near a fault line.

"You inject the fluid in a fault, it gets slippery," making it easier for movement to occur, he said.

But that's not what happened here, he said.
