The 100-foot deep, 66-foot wide circular hole is actually a “piping feature” according to geologists, caused by the fact that much of Guatemala City is build on pumice fill, up to 600 feet of it in some areas.
I still find it odd that it is so round. More like Mel Water’s Devil’s Hole, near Ellensburg Washington, or the glowing The Door to Hell outside Darvaz Turkmenistan (or Uzbekistan), with out the creepy dead sheep or red glow.
In 2007, a 330-foot-deep sinkhole claimed the lives of three people in Guatemala City. This one credited to a broken sewer line.
The pit emitted foul odors, loud noises and tremors, shaking the surrounding ground. A rush of water could be heard from its depths, and authorities feared it could widen or other sinkholes could open up.
The hole in in 2007 was blamed on UFOs by some and it seems a lot of the chatter about the new one being related to a UFO sighting is recycled from then.
