Analysis of the swarm has found no link between this relatively shallow drilling and the earthquakes, but has instead suggested a link with deep waste disposal drilling similar to that identified at the Rocky Mountain Arsenal in the 1960s, and has led to a moratorium on such drilling being proposed covering an area of {{convert|1150|mi2|comma=off|-1}}.[4] See also
