[36] [37] Material shifted by subsequent earthquakes and the waves reached to what are now Texas and Florida, and may have disturbed sediments as far as 6,000 kilometers (3,700 mi) from the impact site. [38] [34] [39] The impact triggered a seismic event with an estimated moment magnitude of 9–11 M w . [31]
The Chicxulub impact is believed to have triggered earthquakes estimated at magnitude 10 – 11.5, [1]: p.8 releasing up to 4000 times the energy of the Tohoku quake.
The authors – who include Walter Alvarez – postulate that shock of the impact, equivalent to an earthquake of magnitude 10 or 11, may have led to seiches, oscillating movements of water in lakes, bays, or gulfs, that would have reached the site in North Dakota within minutes or hours of the impact. This would have led to the rapid burial of ...
The huge space rock known as the Chicxulub impactor is widely believed to have ended the reign of ... the team searched for isotopes of ruthenium in the geological remnants of the Chicxulub impact ...
By April 1st, a scientific expedition will start drilling into the Gulf's Chicxulub impact crater to study how life recovered following the mass extinction at the end of the Cretaceous period. The ...
The pure destruction of the Chicxulub impact had devastating consequences for nearly all life on Earth, wiping out roughly three quarters of all living species. It’s the sort of historical story ...
Supporters of the Alvarez hypothesis have concluded that the sandstone is the result of a massive tsunami caused by the Chicxulub impact that sandwiched the sand between the shocked quartz layer and the iridium clay. Keller's analysis of the strata between the spherules and iridium clay concludes that the material was laid down over as much as ...
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago. Dinosaur-killing asteroid was ...
