^aUTM zone 43. The horizontal mislocation of this explosion is 1,047 m; the vertical mislocation is 730 m. Exact parameters from Mikhailova and Sinyova (2010). In addition, the exact parameters are compared to the location of the Preliminary Determinations of Epicenters (PDE) and GEOFON catalog (differences relative to exact location).
