Thanks guys. I think that's solved it. I found that A 10,000 kg rock, with 10 m drop, is about 1 MJ, which is about 0.28 kWh And, 1 ton dynamite/tnt is approx 4.184 gigajoules = 1162 kWh So there is no real possibility to create an impact on the ground by dropping a large boulder, equivalent...

Thanks guys. To clarify my question, what I am after is, what mass of rock I would need to drop from say 20 meters, that would send an equivalent seismic wave into the ground to match a 1 ton dynamite blast. Hope that's clearer. The physics units are pretty complex for a novice, so I'll avoid...

Can someone help me to calculate the approximate impact on the Earth (as in a mining explosion), of 1 ton of dynamite. And also the equivalent impact of say a 1 ton rock dropped from 10 meters. Trying to estimate this for writing purposes, I very roughly got: Impact of 1 ton of dynamite, Work...
