Earth: 12 742 km and 3737px
Split diameter: 730px or 2.4891e6m
split height: 135px or 406 307m
Volume of half ellisoid (more actually but whatever) :  1.49325e18m^3
Density of water: 1000kg/m^3
Mass: 1.49325e21 kg
Distance travelled by wave: 2 522 044 meters
Speed: 21 017 030m/s or 7%c sub relativistic+
KE= 3.298e35 Joules or 78.8 Yottatons 
However it's and omnidirectional wave type thing so it's atleast twice this at 157.6 yottatons
