Huntington, Utah — A seismologist who detected ground tremors was the first to notify authorities of the cave-in that trapped six miners, even before mine officials called for an ambulance, according to 911 recordings.
University of Utah seismologist Walter Arabasz made his call about a potential problem at the Crandall Canyon mine early on Aug. 6, four minutes before mine officials made their call.
The 911 tapes obtained Monday by The Associated Press showed that from the earliest moments scientists suspected the shaking came from a mine collapse, not a natural earthquake, as mine co-owner Bob Murray has maintained throughout the ordeal that has entered its fourth week.
"Just from the general character of the seismic event, it looks like it might be a coal-mining event," Arabasz said on the tapes.
Also Monday, bad weather delayed drilling on a seventh hole and also postponed plans to drop a $100,000 robotic camera into an earlier hole for a long-shot effort to locate the men.
"There's a lot of rain," Colin King, an attorney for the families, said after a briefing from federal mine safety officials. He said the road had been washed out in places.
As the saga entered a fourth week, Emery County authorities released tapes that described the early hours of the disaster.
The first 911 call came at 3:47 a.m. from Arabasz in Salt Lake City, 120 miles north of the mine. At 3:51 a.m., a mine employee called for an ambulance.
"We had a big cave-in up here, and we are probably gonna need an ambulance. We're not for sure yet because we haven't heard from anybody in the section," a voice identifying himself as Mark Toomer told a 911 dispatcher. "But we're mostly likely going to need one up here."
Arabasz told the dispatcher the seismic event registered as 4.0 magnitude at 2:48 a.m., and it was 3.1 miles west-southwest of the mine entrance. The severity of the event was later revised to 3.9 magnitude.
The six miners have not been heard from since the cave-in, which filled a mine shaft with rock and coal in the area where the men were working. No one knows whether the men survived the collapse.
Mine officials and federal regulators have worked unsuccessfully to locate the miners, drilling a half-dozen vertical holes into the mountain in hopes of finding signs of life.
Horizontal tunneling through the tons of debris inside was halted Aug. 16 after a second cave-in killed three rescuers, including a federal safety inspector, and injured six others.
