Potential Lake Trio durability upgrade

[The_real_cal_howard]

I'm going through my Pearl play through again, and remembered the galactic bomb, which was felt all the way in Canalave City starting from Valor Lakefront. And all this did was draw out Azelf. (P.S. A bunch of Magikarp tanked it too lol). Can someone tell me if this is above island level?

That's a range feat. It's yield is probably insignificant to actually destroying the Lake.

I was hoping we could use an earthquake calculator to get a yield.
