In April 2014, scientists reported finding evidence of the largest terrestrial meteor impact event to date near the Barberton Greenstone Belt. They estimated the impact occurred about 3.26 billion years ago (during the Paleoarchean era of the Archean eon of the Precambrian supereon) and that the impactor was approximately 37 to 58 kilometers (23 to 36 miles) wide, roughly five times larger than the impactor responsible for the Chicxulub crater in the Yucatán Peninsula, which was around the size of Mount Everest. The gigantic impactor was estimated to have collided with the Earth at a speed of 20 kilometers per second (12 miles per second), releasing an enormous amount of energy and triggering magnitude 10.8 earthquakes across the planet, as well as generating megatsunamis thousands of meters high. The crater from this event, if it still exists, has not yet been found.
