Usually we’re finding D.U.M.Bs with a consistent depth of 10 km, this is different. I experienced two earthquakes last year, a 5.7 was exactly 10 km down and the epicenter was directly underneath a copper mine with some known trafficking activities. The other that was also a 6.5 was about 20 km down, but the above ground location was like 7,500 feet above sea level.
what is the significance of that depth?
