An asteroid impact with Earth of Consequences


Geological studies conducted over the last decades have shown us that our planet has undergone a similar meteoric bombardment suffered by the Moon, and even more intense. In fact, due to its greater gravity, the impact rate on Earth is 1.5 times higher than our natural satellite. 


The size range of objects striking bodies is between a few meters to others of several kilometers across, and producing very different effects of different factors: the diameter of the shock, their speed, their density, the place to occur impact either on sea or land, etc.. An example of this was the "Tunguska Event" which little impact (June 30, 1908) has gone unnoticed, because it took place on a spot on the planet virtually underpopulated. What would have happened if the case occurred on an urban or densely populated area?
