New calculations show that the deadly Crandall Canyon mine collapse -- which registered as a magnitude-3.9 earthquake -- began near where miners were excavating coal and quickly grew to a 50-acre cave-in, seismologists say in a report on the tragedy. The University of Utah Seismograph Stations estimated the size of the collapse is about four times larger than was thought shortly after the time of the Aug. 6, 2007, disaster.
