The Chicxulub crater (IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo (not the larger coastal town of Chicxulub Puerto ). [ 3 ]

The top of the melt sheet, which is the, "crater floor" and base of the post-impact sedimentary fill, ranges from 1.2 to 1.6 km below sea level as confirmed by drilling (Gulick et al. 2013:44). Interpretation of geophysical data indicates that the sedimentary fill on top of the melt sheet is as deep as 1.9 km (Gulick et al. 2013:44).
As originally proposed in 1980 [9] by a team of scientists led by Luis Alvarez and his son Walter, it is now generally thought that the K–Pg extinction was caused by the impact of a massive asteroid 10 to 15 km (6 to 9 mi) wide, [10] [11] 66 million years ago causing the Chicxulub crater, which devastated the global environment, mainly ...
Chicxulub Pueblo (Mayan pronunciation: [tʃʼikʃuluɓ] Ch’ik Xulub) is a town, and surrounding municipality of the same name, in the Mexican state of Yucatán. At the census of 2010, the town had a population of 4,080 people. The center of the Chicxulub Impact Crater (approx 21°20'N 89°30'W) is off the Yucatan coast, near Chicxulub Puerto
"The size and damage that would have been wrought by the Chicxulub impact is in agreement with the theory postulated by the late physicist Luis Alvarez and his son, geologist Walter Alvarez, for the extinction of the dinosaurs." I feel this sentence needs a re-write; the proposed damage caused by the impact cannot be in "agreement" with the ...
A volcanic crater is a bowl-shaped depression in the ground caused by volcanic activity, usually located above the volcano's vent. [11] During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava.
