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.
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.
Definitely not the size of Texas. Estimated 10-15 km across.
I’m not a planetary geologist, but I was just thinking more like afterwards, as the planet healed, and water shifted around.

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.
