The Bermuda Triangle is an area in the Atlantic Ocean between Bermuda, Puerto Rico, and Florida where over 1000 ships and planes have disappeared under mysterious circumstances without evidence of bad weather or mechanical failures. Some theories for disappearances in the Bermuda Triangle include methane gas eruptions from the seafloor that could lower water density and cause sinkings, faulty compasses that led to navigation errors, strange electromagnetic fogs that engulfed vessels, and supernatural explanations. Many famous disappearances in the Bermuda Triangle include Flight 19, the USS Cyclops cargo ship, and the Mary Celeste ghost ship.
