Magikarp, the worst Pokémon. But, we have been underestimating his power. The splash. In Magikarp Jump, the impact of Magikarp landing is so hard, that it pulverizes the ground, which you see is rock. Lets get to that.
Magikarp height: 544 px/0.889 meters
Magikarp length: 521 px/0.85141360294 meters
Magikarp length: 142 px/0.85141360294 meters
Distance from Magikarp and the ground: 49 px/0.29379765171 meters
Timeframe: 0.18 seconds
0.29379765171/0.18 is 1.63220917617 m/s for the speed.
Time Magikarp was in the hole: 0.54 seconds
(1.63220917617/0.54)/2 (due to the round trip) is 1.51130479275 meters for the depth of the hole. That will be the height.
Magikarp length: 119.5 px/0.85141360294 meters
Hole diameter (eyeballing due to the awkward shape of Magikarp, so this is the estimated diameter overall): 107 px/0.76235360263 meters (0.38117680131 meters for the radius)
(Pi*0.38117680131^2)*1.51130479275 is 0.68985029589 m^3 for the volume, or 689850.2958900001 cm^3
This appears to be pulverization since the fragments are nowhere to be seen.
689850.2958900001*214.35 is 147869410.924 joules/147.869410924 megajoules, or Small Building Level.
This should pretty much scale to its strength and durability, as they are able to harm each other who could do the same feat.
I think Violent Fragmentation may be the case here, as suggested by DMUA, considering the pieces were just scattered off screen, probably.
689850.2958900001*69 is 47599670.4164 joules/47.5996704164 megajoules, or Small Building Level.
