Aftershock Analysis for SPE2
Jerry J. Sweeney, Office of Defense Nuclear Nonproliferation USDOE National Nuclear Security Administration (NNSA), P.E. Harben · 2012
This is the second report on a study of possible seismic aftershocks associated with chemical explosions in granitic rock. The Source Physics 2 experiment (SPE2), consisting of a 2000 kg TNT equivalent chemical explosion at a depth of 45 m, was detonated on October 25, 2011 (day 298). A report by Sweeney and Harben (2011) describes results of aftershock analysis of the SPE1 experiment – a smaller 100 kg explosion at 60 m depth -- that took place in the same location on May 3, 2011.
