Did We Discover a Large Undersea Alien Base in the South-East of Puerto Rico?

The archipelago of Puerto Rico, in the Caribbean Greater Antilles, is a land full of riddles and surprises that for many decades has been a hot spot of UFO / extraterrestrial activity. This activity has been connected, in many occasions, with the sea surrounding our territory. Now, we have made a startling finding which may, perhaps, shed more light on this enigma.

A year ago we discovered mysterious anomalous structures which lie on the seafloor in the south and east of Puerto Rico, which extend from a point in the south of the city of Ponce to another point in the south of the island-municipality of Vieques, in the east. 

We discovered them while studying the seabed around the island using NOAA images derived from that agency’s studies by means of satellite imaging and sonar bathymetry, etc. The structures are much too geometrical in shape, and that detail makes us think they are complex artificial structures, and not the product of casual natural geological formations. 

The first anomalous structure consists of an extremely large rectangular structure which shows at its left end what appears to be an entrance into the seafloor. The structure and its ‘entrance’ are geometrically-shaped too, and again, they seem to be of an artificial origin.  

But also, starting right out from the top left of that structure there is what seems to be huge roads or tunnels which connect to the continental shelf in the south of the city of Ponce, in southern Puerto Rico. 

‘Coincidentally’, back in the late 1980s many citizens of the city of Ponce pleaded the media to ask the local and state authorities to investigate something that worried them: at night loud noises and loud buzzing sounds were being felt. It was as if someone was drilling or boring underground with some powerful machines. They also reported hearing great noises like those of large falling rocks which tumbled underground. 

For several days the locals and other curious citizens from nearby towns made night vigils, but eventually the media stopped covering the issue and it was silenced. Subsequently the noises and vibrations stopped and the mystery was forgotten. 

Now, after discovering the submerged roads or tunnels that connect with the continental shelf in the south of the city of Ponce, I think on the possibility that the two things are related. Did the builders of the structures on the seabed south and southeast of Puerto Rico also built an underground access to the city of Ponce? Maybe another underground facility there?
