His name was Barnes Wallis. I was close but thought I would correct it after looking it up to be sure.
I have also heard of one that caused earth quakes but probably not the same as what you are talking about. This was a bomb and bunker buster of sorts. It was a 22,000lb known as "The Grand Slam" designed by a Mr. Willis ,I believe, it was for the UK's Royal Air Force in World War II. The reason it was not widely used I believe is because it was so large and only a few airplanes could carry it. Also as we all know a little later it would be over shadowed by the atomic bombs the US dropped on Hiroshima and Nagaski to end the war and when a bomb is so serious it can end a war that is note worthy. Altho "The Grand Slam" was a large bomb the only thing it really did was burrow deeply in the ground, explode and cause earth quake like trimmers that would bring down most builds.
