I'm aware that Derpaholic already calculated this, but I found some good stuff while going back over it.

Derpaholic got the blue moon to be 2,039.8km in diameter. The yellow moon is at least as big, considering it's much, much, much farther away from Earth and the gravity is greater.
Anyway, the gravity on this moon is about the same as Earth's. According the Derpaholic's blog, the formula for the mass of this celestial body would be m=gr^2/G.
m=(9.8*(2039800/2)^2)/6.673e-11
m=1.53e23kg
Now that we have mass, we need velocity.
(2039800/88)655=15,182,602.3m
The material expands that far in 17 frames, while the video runs a frame-rate of 29fps. For anyone who asks, those chunks of rock in the middle are actually flying toward perspective, not caught in the middle of the blast.
(15182602.3/2)/(17/29)=12,949,866.67m/s
KE=.5mv^2
KE=.5*1.53e23*12949866.67^2
KE=1.283e37J
or about 3 ninatons.
But wait, there's more
After Lucemon kicks the shit out of the Chosen Children, Patamon, Salamon, and Lopmon escape the explosion, which means radius of the explosion minus radius of the moon divided by a time-frame. We know for a fact that the three Digimon are on the surface when the moon cracks, and we see that happen 23 frames before the above screen cap.
((15182602.3/2)-(2039800/2))/(23/29)=8285679.71m/s
or about mach 24,370.
