On Thursday, January 19, 2012, locals were recorded staring into a giant sinkhole in the Republic of Dagestan, which is a republic of Russia. Strange sounds seemed to be emanating from the sinkhole, reminiscent of the sounds commonly referred to as "UFO sounds" or "sounds of the Apocalypse" that began escalating in popularity in 2011 and reached a crescendo in January 2012.

According to an update by UFO Scandinavia: "The hole has been measured to be no more than 30 meters. A girl was saved at the same time. She was thrown down there by her husband. The sinkhole is not new and has been known by the locals."
