How to analyze GBU-57 results

A 1 kt explosion has to have 100 m depth of burial for full containment in hard rocks. No debris. No immediate crater. No gas venting. A well-known measure to achieve containment is to collapse the tunnel/borehole by shock wave. If one sees gas venting from the hole (borehole) - the bomb has not reached the underground void space. The damage radius (no damages beyond and progressively increasing to the epicentre) in hard rocks is approximately 100[m]*yield [kt**(1/3)] (see the case with 1 kt bomb). For 100 tons it would be ~50 m, for 10 tons - 21 m. The charge of GBU-57 in 2.5 tons with the potential of 5 ton TNT. Damage zone - 17 m. These are basics for underground testing known since the 1940s.

Overall, one has to get information from various accurate physical observations to get a professional opinion on the result of the action. The absence of results of such a scientific analysis in open public/professional discussion says about the case more than the "absence of the Epstein list" about the US democracy.
