Is there a sinkhole in the ocean?
Scientists are flocking to Florida’s Gulf Coast for a glimpse of a mysterious 425-feet-deep “blue hole” on the ocean floor. The glowing mystery hole, about 155 feet below the water’s surface, is similar to the sinkholes seen on solid land, according to the National Oceanic and Atmospheric Administration.

How do sinkholes happen?
Sinkholes are formed when the land surface above collapses or sinks into the cavities or when surface material is carried downward into the voids. … Sinkholes can be triggered by human activities such as: Overwithdrawal of groundwater. Diverting surface water from a large area and concentrating it in a single point.
Can a sinkhole be fixed?
If the sinkhole is not affecting a house or other structure, and has a reasonable size — 2 to 5 feet in both diameter and depth — then you can repair it yourself. A large sinkhole will most likely require excavation and a more complex filling operation.
Do humans cause sinkholes?
Human activity can create sinkholes, too, for example, via collapsed or broken sewer and drain pipes or broken septic tanks, improperly compacted soil after excavation work, and buried trash, logs and other debris. They can also occur from the overpumping and extraction of groundwater and subsurface fluids.
What is inside a sinkhole?
A sinkhole has no natural external surface drainage – when it rains, all the water stays inside the sinkhole and typically drains into the subsurface. … Some actually form water, and you’ve probably seen this in the form of little ponds in limestone.
