I already made a calc for a feat of this nature here but now I’m unsure if I did it right
Primary calc: https://vsbattles.fandom.com/wiki/User_blog:GraveDigger84/Enceladus_shakes_Mount_Diablo
Secondary calc: https://vsbattles.fandom.com/wiki/User_blog:GraveDigger84/Percy_shakes_Hubbard_Glacier
So I had a few questions about using the Mercalli scale to calc shaking things
1. Formula? I thought it was 0.5*(Mass)*(Velocity from Mercalli scale)^2 = Energy in Joules but then I saw other users computing it a different way, including using mass instead of volume.
2. Use case? In the cases I showed where either a mountain or glacier is being shaken by a character striking it (the second one might be caused by powers but eh), is this formula good to use in these cases?
3. Units? This tends to trip me up sometimes. M^3 for volume, kg for mass, that’s all fine right? And when I’m bringing in densities that come in g/cm^3, can I compute the mass in grams and then convert it later? Also for mountains, what material do I choose to get the density?
4. Velocity: if the graph for example on intensity IV says 1.41-4.65, which one do I put in the formula? And let’s say I used 4.65, do I have to input it as .0465? Since that’s what I saw other people doing. Also, how do I decide which velocities to use?
