A study published Jan. 14 estimates the crater at 69 to 93 miles in diameter, more than twice as big as previously thought. If the projections are correct, the so-called Alamo impact would rank as Lonar Impact Crater is a simple meteorite impact crater carved out on the ~ 65 Ma old Deccan tholeiitic flood basalts. The crater, though scoured in a basaltic terrain, is still preserved in its most pristine form, with a central crater lake. The geomorphology, geochemistry, geochronology, hydrology, geophysical parameters, and structural aspects of Lonar Crater have been explored in detail Across the history of our planet, around 190 terrestrial impact craters have been identified that still survive the Earth’s geological processes, with the most recent event occurring in 1947 at the Sikhote-Alin Mountains of south-eastern Russia. The largest of these events occurred at Vredefort in the present-day Free State province of South The Canyon Diablo meteorite impacted the Earth about 50,000 years ago, creating the Meteor Crater. The crater is about 4,000 feet wide and 600 feet deep. The impact of the meteorite excavated the crater, lifting up 175 million tons of sandstone and limestone, and tossing much of it outside the crater. The crater is one of the world’s best The Vredefort crater is the largest certified impact crater on Earth. In the present Free State Province of South Africa, what remains of it is more than 300 kilometers (190 mi) from when it was created. It is named after the town of Vredefort, near its center. Although the crater itself has long been worn away, it is known as the Vredefort 1. South Pole–Aitken basin, the moon. Our first crater is a big one: the biggest, deepest and oldest impact crater on the moon. It is 2,500km diameter, 6.2 to 8.2km deep and formed roughly 4.2 The asteroid smashed into Earth, leaving a thirty-one-kilometer-wide, one-kilometer-deep crater. The crater is big enough to contain the entire city of Washington D.C. Here's what it could do to Earth. Comet Bernardinelli-Bernstein, the largest comet ever discovered, has a nucleus that's approximately 119 kilometers across. If such an object were to strike Earth PG2H.
