<P> Lōihi Seamount ( also known as Lōʻihi ) is an active submarine volcano about 35 km ( 22 mi ) off the southeast coast of the island of Hawaii . The top of the seamount is about 975 m ( 3,000 ft ) below sea level . This seamount is on the flank of Mauna Loa , the largest shield volcano on Earth . Lōihi , meaning `` long '' in Hawaiian , is the newest volcano in the Hawaiian - Emperor seamount chain , a string of volcanoes that stretches over 5,800 km ( 3,600 mi ) northwest of Lōʻihi . Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire , Lōʻihi and the other volcanoes of the Hawaiian - Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary . Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot , and as the youngest volcano in the chain , Lōihi is the only Hawaiian volcano in the deep submarine preshield stage of development . </P>
