What are these mysterious circles discovered underwater in the vicinity of Dugi Otok Island, Croatia?
Each measures 50 meters diameter and is separated by 300 meters from the next one.
These mysterious and unknown circles are evenly spaced apart and are found around several Croatian islands in the Adriatic Sea.
They consist of unexpectedly rough terrain, devoid of any floral life, as if some Godzilla-like being walked the Adriatic’s bottom, leaving its circular footsteps in the underwater grassland.
These weird and still unexplained circles baffle scientists and worry residents.
Some believe, these strange underwater ‘craters’ were created by aliens, since many have reported weird lights in the sky at the exact same locations.
Plate boundary movements? Illegal dynamite fisherman? Oil drilling near Dugi Otok? War protection (anti-submarine bombs or mines) to prevent from invasions? Time will tell!
