From article: "But compressing MDA and then releasing the pressure and heating it released a large burst of energy. That energy, released as the amorphous ice recrystallizes, could set off icequakes, for example." Probably not large, but enough to melt some surrounding normal ice? Or causes material to expand rapidly by several percent?
