The Chicxulub crater (/ˈtʃiːkʃᵿluːb/; Mayan pronunciation:[tʃʼikʃuluɓ]) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. The date of the Chicxulub impactor, which created it, coincides precisely with the Cretaceous–Paleogene boundary (K–Pg boundary). The crater is more than 180 kilometers (110 miles) in diameter and 20km (12mi) in depth, making the feature the third of the largest confirmed impact structures on Earth; the impacting bolide that formed the crater was at least 10km (6mi) in diameter.
The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater, and gave up his search. Through contact with Alan Hildebrand, Penfield obtained samples that suggested it was an impact feature. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas.

The Impact Crater in Mexico which Wiped out the Dinosaurs; Chicxulub Crater
The largest impact crater on the planet to form in the last 1 billion years is located on the Yucatan Peninsula. Known as the Chicxulub Crater, it measures 180 kilometers or 110 miles wide. Its formation caused the extinction of the non avian dinosaurs 66 million years ago, causing a long term impact winter. If not for this ancient event, the dominant life forms on the planet would still be giant reptiles. This video will discuss this massive impact crater and how it formed.

Chicxulub impact visualization
A visualization of the immediate and long-term environmental effects of the impact event which marked the end of the Cretaceous period, circa 65 mya. Produced by Radek Michalik and David Dolak in collaboration with the Science Institute at Chicago's Columbia College. I DID NOT MAKE THIS.
If such an impact were to occur today, the best strategy for immediate survival would be to be in a different hemisphere when it happened. The kinetic energy of a six-mile-wide rock piling into the earth at 50,000 mph must be conserved, and in order to do this much of this energy is converted to thermal energy - enough to cause third-degree burns from seven hundred and fifty miles away, and to light you on fire if you are much closer. Little to nothing would survive within six hundred miles of the impac...

Since the 1980s, scientists have believed that the main culprit for the dinosaur extinction was an asteroid. It came from the far reaches of the solar system, and was the size of Mount Everest.

If such an impact were to occur today, the best strategy for immediate survival would be to be in a different hemisphere when it happened. The kinetic energy of a six-mile-wide rock piling into the earth at 50,000 mph must be conserved, and in order to do this much of this energy is converted to thermal energy - enough to cause third-degree burns from seven hundred and fifty miles away, and to light you on fire if you are much closer. Little to nothing would survive within six hundred miles of the impact zone - note the "scorched earth" appearance of the North American continent at KT + 2 weeks. Other immediate effects include a major earthquake, an airblast capable of leveling forests and buildings, semi-molten ejecta raining from the sky and sparking global wildfires and, once the shockwave reaches the antipodal point of the Earth, massive volcanic eruptions which can last for many thousands of years (such as those that formed the Siberian Traps).
A modern theory states that not one, but several impacts ushered forth the mass extinction to follow, including the impacts which created the Silverpit Crater in the English Channel, and Boltysh Crater in the Ukraine; though neither were as large or devastating as Chicxulub, they are possibly the result of an impact similar to comet Shoemaker-Levy 9 on Jupiter.
The University of Arizona has released a calculator for estimating the effects of small- to large-scale impact events.

The Chicxulub crater (/ˈtʃiːkʃᵿluːb/; Mayan pronunciation:[tʃʼikʃuluɓ]) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named. The date of the Chicxulub impactor, which created it, coincides precisely with the Cretaceous–Paleogene boundary (K–Pg boundary). The crater is more than 180 kilometers (110 miles) in diameter and 20km (12mi) in depth, making the feature the third of the largest confirmed impact structures on Earth; the impacting bolide that formed the crater was at least 10km (6mi) in diameter.
The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán during the late 1970s. Penfield was initially unable to obtain evidence that the geological feature was a crater, and gave up his search. Through contact with Alan Hildebrand, Penfield obtained samples that suggested it was an impact feature. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas.
