Hello
in my free time i was trying to find a formula for each one of these natural phenomenon to give a good approximation of the AP linked to them, and i wanna know if they are reliable/usable for estimating the power;
Volcano
the method was already accepted in this calculation
"A third way is to consider how much the pressure in the magma chamber is reduced times the reduction in volume, E=ΔP⋅VE=ΔP⋅V. A pressure drop of 5 MPa is apparently typical, and the volume reduction is proportional to the ejected volume (with some scaling factor from packed rock to ejecta)" (here)
the ejecta volume can be calculated with this formula : 10^(4+i) = volume in cubic meter with i the VEI
(a VEI of 3 will give us 0.01 km^3 [10000000 m^3] which correlates with wikipedia)
we just need to put in the typical pressure change, 10000000 * 5*10^6 = 5e+13 joules, or Town level
when we put a VEI of 8 (Highest VEI), we get
10^(4+8) * 5 * 10^6 = 5e+18 Joules, which is fairly close to maximum energy possible for a volcano (if i did not misunderstand it)
"Thus, the largest eruptions release elastic energy of the same order of magnitude as the largest earthquakes, suggesting that 10^19 J may be close to the maximum elastic energy that is available for driving earthquakes and volcanic eruptions."
The final formula is 10^(4+i) * 5*10^6 = energy in joule
so can this be possibly added to the Calculation page ? as a reference for volcano based feat (the same page we have but for earthquake)
also i want to know if theres a formula for tsunamis, or do we just get the kinetic energy
