Assuming Apophis is a 325-metre-wide (1,066 ft) stony asteroid, if it were to impact into sedimentary rock, Apophis would create a 4.3-kilometre (14,000 ft) impact crater.[
[I]f a 2036 Earth impact were to occur... a narrow corridor a few kilometres wide...extending across southern Russia, across the north Pacific... then right between Nicaragua and Costa Rica, crossing northern Colombia and Venezuela, ending in the Atlantic...
[T]he hypothetical impact of Apophis in countries such as Colombia and Venezuela, which were in the path of risk, could have more than 10 million casualties.
However, the exact location of the impact would be known weeks or even months in advance, allowing any nearby inhabited areas to be completely evacuated and significantly decreasing the potential loss of life and property.
A deep-water impact in the Atlantic or Pacific oceans would produce an incoherent short-range tsunami with a potential destructive radius (inundation height of >2 m) of roughly 1,000 kilometres (620 mi) for most of North America, Brazil and Africa, 3,000 kilometres (1,900 mi) for Japan and 4,500 kilometres (2,800 mi) for some areas in Hawaii.
