Fuuko summons a meteorite which destroys a building and creates a large crater

Andy steals a knife from this dude and cuts down him and his buddies before he can even fully comprehend it.

First time doing a calc ever so if I do anything wrong feel free to correct me.

Average temperature of a glacier is -60°C to 0°C so I'll split it into 3 ends Low (0°C), Mid (-30°C), High (-60°C).

1. Low End

Weight = 10,000 Ton = 10,000,000 kg = 1e+7 kg

Heat of Fusion of Water = 334000 J/kg = 3.34e+5 J/kg

Weight * Heat of Fusion = 1e+7 * 3.34e+5 = 3.34e+12 J

3.34e+12 J = 798.28 Tons of TNT [Multi-City Block]

2. Mid End

Specific Heat of Water = 4,184 J/kg°C

Temperature Change = 30°C

Weight * Specific Heat * Temperature = 1e+7 * 4,184 * 30 = 1.25e+12 J

1.25e+12 + 3.34e+12 = 4.59e+12 J

4.59e+12 J = 1.09 Kilotons of TNT [Small Town]

3. High End

Temperature Change = 60°C

Weight * Specific Heat * Temperature = 1e+7 * 4,184 * 60 = 2.51e+12 J

2.51e+12 + 3.34e+12 = 5.85e+12 J

5.85e+12 J = 1.39 Kilotons of TNT [Small Town]

Assume the Explosion takes place at the Karman Line and it looks about as big as the moon does from Earth's Surface
