Exclusive events for central collision of [sup 94]Kr on Ag/Br emulsion at a bombarding energy of 70--120 MeV per nucleon point to an extremely large flow energy of the order of 10 MeV per nucleon for intermediate mass fragments. We show that this large radial flow energy is associated with an explosive breakup of the excited matter in the very early stage of the collision process.
