This reminds me of the video I saw on a TV show called Real Video. A small beach town on the east cost had a huge whale beach itself in 1970. It was dead, and they a lot of TNT laying around, so...
100 lbs. chunks were flying as far as 300 yards. Smaller pieces were found a mile away. No need to worry, though. The watching towns folk were at a safe 100 yards away from the exploding whale at the time of detonation.
Amazingly, no one was hurt or killed. But, a few cars needed some body work and the local cleaners were hiring.
