Spherules can be seen in this sample taken from another meteorite impact. Then all of a sudden, you have a giant tsunami, sweeping by and ripping up the seafloor.”This graphic shows the sequence of events following the S2 giant meteorite impact. When oceans boil and evaporate, they form salts such as those observed in the rocks directly after the impact, Drabon said. The researchers studied layers in this rock and determined that a global tsunami was initiated by the S2 meteorite impact 3.26 billion years ago. “Life during the time of the S2 impact was much simpler,” she said.
