A cartoon incorporating both the seismic observations and the computer simulations, summarising the sequence of events that we hypothesise formed the Nadir Crater. These show the initial impact of a 400 m diameter asteroid in (A), the immediate effects of the impact after a few seconds in (B), including vaporisation of sediment and water, the formation of a large fireball, the generation of shock waves and pressure waves equivalent to a magnitude 6.5 earthquake and the formation of an 'ejecta curtain' of rock and water several kilometers high. After 30 seconds (C) the ejecta curtain collapses to form an initial rim wave tsunami. Meanwhile, in the subsurface, the rocks below the crater floor rebound to form the central uplift. In (D), we can see that the weakened sediments/rocks on the side of the crater collapse in towards the crater and that the water resurges back into the crater, transporting some of the sediment that was initially ejected back into the crater itself.
