Scientists have yet to reach the bottom of the Taam Ja' Blue Hole in Mexico's Chetumal Bay, which new measurements hint could be connected to a labyrinth of submarine caves and tunnels.
Mexico's Taam Ja' Blue Hole is the deepest known underwater sinkhole in the world, researchers have discovered — and they haven't even reached the bottom yet.
New measurements indicate the Taam Ja' Blue Hole (TJBH), which sits in Chetumal Bay off the southeast coast of the Yucatan Peninsula, extends at least 1,380 feet (420 meters) below sea level.
That's 480 feet (146 m) deeper than scientists initially documented when they first discovered the blue hole in 2021, and 390 feet (119 m) deeper than the previous record holder — the 990-foot-deep (301 m) Sansha Yongle Blue Hole, also known as the Dragon Hole, in the South China Sea.
It’s not far from it, but this is on the eastern side of the Yucatán peninsula. The Chicxulub crater is on the Northwestern side of the peninsula. I’m not equipped to weigh in on if it may be related, though.
Blue holes are generally created via similar methods to sink holes. Basically sandstone erosion, also I dont think an impact like that would leave any cave systems. Remember that asteroid was about the size of Texas, im pretty sure most things in the region we're nuked and I cant imagine much more than a crater could be created.
I can actually correct myself, apparently at the edge of the crater sink holes do form. But I still suspect the two are pretty much unrelated due to distance.
