Sure enough, the prehistoric Earth was rocky.
New research found it The asteroid that killed the dinosaurswhich hit Mexico’s Yucatan Peninsula 66 million years ago, also caused a “massive earthquake” that shook the planet weeks or months after the impact, EurekAlert reports.
After a 10-kilometer impact of space rock, seismic activity estimated to be 50,000 times stronger than the devastating 9.1 earthquake that struck Sumatra, Indonesia, in 2004 occurred.
Geologist Herman Dario Bermudez – who spent the last year in Texas, Alabama and Mississippi studying famous rock formations that still show probable faults and fractures from an extinction event – says this new dataset complements his findings in the hemisphere. austral in 2014.
While on Gorgonilla Island in Colombia, Bermúdez found spherical deposits – also known as rock strata with tiny glass grains – among further evidence of a major earthquake. These grains are the result of the asteroid’s heat and pressure melting to Earth upon impact, ejecting molten lumps into the atmosphere, which land on the planet like glass due to gravity.
He also found fragments called “tektites” and “microtikites”, which were thrown to Earth by asteroids.
The Colombian stable rocks are thought to “speak from the bottom of the sea”, particularly at a depth of about 2 kilometers. Bermudez found that millions of years old layers of clay and sandstone are still preserved in today’s outcrops due to the vibrations of the impact.
“This is one of the best preserved and is found deep in the sea, so it’s not affected by tidal waves,” he said.
Just above the deposit, fern spores have also been preserved showing the first recovery of plant life after the asteroid impact.
Bermúdez also documented large-scale tsunami evidence resulting from these impacts.
Recently reported Flood waters have risen near space The entire planet is practically flooded while the “miles of elevation” effect is reproduced.
