## Main Question or Discussion Point

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 = approx 1/2 megawatt.

Equivalent dropping a 1 ton rock 10 meters, approx 2/3 megawatt. Probably way off.

I didn't work very long at this and as I'll likely not be confident of getting the answer right, I thought I'd ask some people who would know how to do these calculations.

Appreciate any feedback.
