Sharkano

Sharknado was a cheap, campy movie about sharks in a tornado that became surprisingly popular. It was intentionally ridiculous and silly. But if they wanted a dash of truth, they should have chosen the sharkano, a shark-filled volcano that was actually found by scientists in 2015.

The Solomon Islands' coast is 20 miles from the Kavachi volcano. Even though it was evidently not erupting at the time, it is one of the most active volcanoes in the ocean. The water is still warm, acidic, and sediment-filled. You wouldn't expect to discover life there, and sharks are definitely not to be found there.

They captured footage of hammerhead and silky sharks swimming inside the volcano. As the volcano erupted, scientists intended to tag sharks to observe how their habits changed. According to rumor, either the sharks are aware of an eruption and flee the region, or they erupt with the volcano.
