Vredefort Crater - Asteroid impact date: Estimated 2 billion years ago

263, pp. 786-806. 1965. The Vredefort Impact Crater is the largest crater in the world. While the ridge of the crater itself has worn away over time, the base of the formation remains and is known as the Vredefort Dome or the Vredefort Impact Structure. The Vredefort Crater is one of the biggest known impact craters on earth.

The Vredefort crater is the largest verified impact crater on Earth, Almost immediately after impact, the crater widened and shallowed as the rock below started to rebound and the walls collapsed. The world’s oldest and largest known impact structure was formed. Scientists estimate that when the rebound and collapse ceased, Vredefort Crater measured somewhere between 180 and 300 kilometers wide.

The Vredefort structure is currently regarded the biggest and oldest clearly visible impact structure on Earth. Figure 2 shows how the Vredefort crater formed. The meteorite exploded in a fireball as hot as 20 000 °C and brighter than the Sun. This blasted rock, dust and melted rock into the air but also pressed the rock underneaththe crater violently downwards for a short time. When this rock bounced back a few minutes later, it formed the Vredefort Dome.
