Existing on this earth, away from our eyes, there are many underwater mysteries that are still unveiled. One of these mysteries is the existence of underwater volcanoes. Some of these underwater volcanoes are active while others are inactive. Although these volcanoes are situated under the sea, they can still cause massive destruction if they erupt. Besides causing high intensity earthquakes, these volcanoes have the potential to push large catastrophic tidal waves towards coastal areas.

Based on the height, there are 10 underwater volcanoes that are particularly prominent.
