In order of increasing yield ( most yield figures are approximate ) : As a comparison , the blast yield of the GBU-43 Massive Ordnance Air Blast bomb is 0.011 kt , and that of the Oklahoma City bombing , using a truck-based fertilizer bomb , was 0.002 kt . Most artificial non-nuclear explosions are considerably smaller than even what are considered to be very small nuclear weapons
