The Pacific Ocean is known for being violent. It is hard to believe that there are actually volcanoes that are underwater. These can be just as deadly because they can trigger tsunamis and earthquakes. Then there will be three natural disasters nearest the land. Some of these volcanoes include the Bowie Seamount, Adams Seamount, Axial Seamount, Bounty Seamount, Cleft Segment, Coaxial Segment, Foundation Seamounts, Hawaiian Emperor seamount chain, Loihi Seamount and the Tamu Massif.
Probably of these ten volcanoes, the volcano that is the most deadly would probably be the Hawaiian Emperor seamount chain due to its recent last eruption. It occurred in 2015. A few others erupted recently too. They erupted in the 1980s and 1990s. They were the Axial Seamount, Cleft Segment and the Coaxial Segment.
