Orginal Calc: User blog:KamiYasha/One Piece Calc - Enel's Theoretical Island Destruction (Revised)
Feat Description: Enel destroyed Angel Island from his 1st Raigou. He wanted to destroy the entire Skypiea with his 2nd one. So this is a theoritical Raigou
Current calculation for this is invalid due to not using the currently accepted size of Upperyard;

First Calculation
Picture here: Media:SkypieaIslands.jpg
Upperyard Diameter = 550 px = 10460.906 m
Upperyard Width = 320 px = (320/550)*10460.9058 = 6086.3452 m
Bay Diameter = 224 px = (224/550)*10460.9058 = 4260.442 m
Bay Width = 108 px = (108/550)*10460.9058 = 2054.141 m
Volume of the Bay = (4/3)*pi*(4260.442/2)^3 = 40491381497 m^3
Volume of the Upperyard = (4/3)*pi*(10460.906/2)^3 = 599385898341 m^3
Total Volume = 599385898341 - 40491381497 = 558894516844 m^3 or 5.5889452e17 cm^3
Pulverization = 5.5889452e17*214.35 = 1.1979904e20 Joules or 28.63 Gigatons [Island level]
Vaporization = 5.5889452e17*25700 = 1.4363589e22 Joules or 3.43 Terratons [Small Country level]
RE-CALCULATION
Apparently the latest Databook has given the official height and length of both Going Merry and Thousand Sunny, which is much lower than the one Stefano4444 got by scaling to Usopp, which change the results of Beanstalk and Upperyard’s size and thus the results of the Theoretical Raigou’s feat as well.
