E= 1/2 mv squared. v is a rather large number. On earth, typically 90% would be ablated (leaving 4kg) and the cosmic velocity of a meteoroid this size would all be lost, resulting in the last few miles in free fall at terminal velocity of only 250 m/s. The bolide would more than likely break up first into smaller pieces in our atmosphere. It would give a spectacular fireball but probably never be found. A lunar colony would need a solid rock equivalent roof thickness of at least 15 metres to survive and an air tight inner layer. The depth of the crater itself would be about 8 metres. Realistically, tunnelling in to a mountain is how the lunar colony would have to be built.
