Florida’s ocean floor just collapsed without warning, as sudden oceanic sinkholes emerged offshore. Divers first spotted the bizarre craters after routine sonar scans revealed massive depressions opening directly in the sandy seabed.
A home has collapsed into the ocean in Wilbur by the Sea, in Volusia County, due to severe coastal erosion. The incident has drawn renewed attention to long-term geological changes affecting Florida’s coastline. While the state is known for its beaches and tourism, scientists have documented a range of ongoing developments in nearby waters that are reshaping the seafloor.Researchers are monitoring…
Lake Michigan hides a secret that researchers have spent decades trying to explain. Sonar scans of the deep floor have revealed stone structures that look far too organized to be natural.
Lake Superior is the largest freshwater lake in the world by surface area, covering roughly 31,700 square miles. It holds about three quadrillion gallons of water, which is half of the entire volume of the Great Lakes system. The lake is so deep that its lowest point reaches about 1,333 feet below the surface, and its average depth is around 483 feet.The lake formed through a different process tha…
The ground beneath Lake Michigan just unleashed a massive 8.8 magnitude tremor, and scientists say something profound is shifting far below the surface. Seismographs near the region captured readings that immediately triggered alarms, as the quake’s depth and force defied normal expectations for the area.
In 2022, a team of researchers mapping the floor of Lake Michigan with sonar detected a series of large, circular depressions at a depth of roughly 500 feet. The features, which number in the dozens, range from 300 to 600 feet in width and reach depths of about 40 feet. Their near-perfect circular shape and alignment initially puzzled the scientists, who could not identify a natural process that w…
Twenty-five years after divers first mapped Cuba’s mysterious underwater pyramids, a new expedition finally returned—and the sonar screens went dark before the images ever surfaced. The ancient stone structures, discovered off the coast in 2001, were long dismissed as a geological fluke.
In May 2001, a marine survey team working off Cuba’s Guanahacabibes Peninsula detected unusual formations on the seafloor at a depth of roughly 2,000 feet. The team, led by engineer Paulina Zelitsky and her husband Paul Weinzweig, was under contract with the Cuban government to search for colonial-era shipwrecks. Using side-scan sonar, they located what appeared to be straight edges, circular outl…
For decades, scientists mapped the Great Lakes as a familiar, ancient landscape—until sonar scans revealed something buried beneath the waves that defied everything they thought they knew. The
In 2022, a team of researchers set out to map the floor of Lake Michigan and search for shipwrecks. They expected typical rocky terrain and sandy patches. Instead, their sonar screens revealed vast, perfectly circular craters scattered across the lakebed, sitting about 500 feet beneath the surface.The formations are enormous, ranging from 300 to 600 feet wide and plunging nearly 40 feet deep. Doze…
