Question: What is the largest subaerial volcano in the Hawaiian - Emperor seamount chain?

full_context: Document 1: Hawaii (island): Hawaiʻi ( ; ] ) is the largest island located in the U.S. state of Hawaii. It is the largest and the southeastern-most of the Hawaiian Islands, a chain of volcanic islands in the North Pacific Ocean. With an area of 4028 sqmi , it is larger than all of the other islands in the archipelago combined and is the largest island in the United States. However, it only has 13% of Hawaii's people. The island of Hawaii is the third largest island in Polynesia, behind the two main islands of New Zealand.
Document 2: Puʻu ʻŌʻō: Puʻ u ʻ Ōʻ ō (often written Puu Oo, ] ) is a volcanic cone in the eastern rift zone of the Kīlauea volcano of the Hawaiian Islands. Puʻ u ʻ Ōʻ ō has been erupting continuously since January 3, 1983, making it the longest-lived rift-zone eruption of the last two centuries.
Document 3: Piton de la Fournaise: Piton de la Fournaise (French): "Peak of the Furnace" is a shield volcano on the eastern side of Réunion island (a French department) in the Indian Ocean. It is currently one of the most active volcanoes in the world, along with Kīlauea in the Hawaiian Islands (Pacific Ocean), Stromboli, Etna (Italy) and Mount Erebus in Antarctica. A previous eruption began in August 2006 and ended in January 2007. The volcano erupted again in February 2007, on 21 September 2008, on 9 December 2010, which lasted for two days. and on 1 August 2015. The most recent eruption began on 14 July 2017. The volcano is located within Réunion National Park, a World Heritage site.
Document 4: Kohala: Kohala is the oldest of five volcanoes that make up the island of Hawaii. Kohala is an estimated one million years old—so old that it experienced, and recorded, a reversal of magnetic field 780,000 years ago. It is believed to have breached sea level more than 500,000 years ago and to have last erupted 120,000 years ago. Kohala is 606 km2 in area and 14000 km3 in volume, and thus constitutes just under 6% of the island of Hawaii.
Document 5: Māhukona: Māhukona is a submerged shield volcano on the northwestern flank of the Island of Hawaiʻ i. A drowned coral reef at about 3,770 feet (-1,150 m) below sea level and a major break in slope at about 4,400 feet (-1,340 m) below sea level represent old shorelines. The summit of the shield volcano was once 800 feet (250 m) above sea level. It has now subsided below sea level. A roughly circular caldera marks the summit of Māhukona. A prominent rift zone extends to the west. A second rift zone probably extended to the east but has been buried by younger volcanoes. The main shield-building stage of volcanism ended about 470,000 years ago. The summit of the shield volcano subsided below sea level between 435,000 and 365,000 years ago.
Document 6: Lōʻihi Seamount: Lōʻihi Seamount (also known as Loihi) is an active submarine volcano about 35 km off the southeast coast of the island of Hawaiʻi. The top of the seamount is about 975 m below sea level. This seamount is on the flank of Mauna Loa, the largest shield volcano on Earth. Lōʻihi, meaning "long" in Hawaiian, is the newest volcano in the Hawaiian-Emperor seamount chain, a string of volcanoes that stretches over 5800 km 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 Hawaiʻi hotspot, and as the youngest volcano in the chain, Lōʻihi is the only Hawaiian volcano in the deep submarine preshield stage of development.
Document 7: Hawaiian–Emperor seamount chain: The Hawaiian–Emperor seamount chain is a mostly undersea mountain range in the Pacific Ocean that reaches above sea level in Hawaii. It is composed of the Hawaiian ridge, consisting of the islands of the Hawaiian chain northwest to Kure Atoll, and the Emperor Seamounts: together they form a vast underwater mountain region of islands and intervening seamounts, atolls, shallows, banks and reefs along a line trending southeast to northwest beneath the northern Pacific Ocean. The seamount chain, containing over 80 identified undersea volcanoes, stretches over 5800 km from the Aleutian Trench in the far northwest Pacific to the Loʻihi seamount, the youngest volcano in the chain, which lies about 35 km southeast of the Island of Hawaiʻi.
Document 8: Meiji Seamount: Meiji Seamount, named after Emperor Meiji, the 122nd Emperor of Japan, is the oldest seamount in the Hawaiian-Emperor seamount chain, with an estimated age of 82 million years. It lies at the northernmost end of the chain, and is perched at the outer slope of the Kuril-Kamchatka Trench. Like the rest of the Emperor seamounts, it was formed by the Hawaii hotspot volcanism, grew to become an island, and has since subsided to below sea level, all while being carried first north and now northwest by the motion of the Pacific Plate. Meiji Seamount is thus an example of a particular type of seamount known as a guyot, and some publications refer to it as Meiji Guyot.
Document 9: Kīlauea: Kīlauea ( , ; ] ) is a currently active shield volcano in the Hawaiian Islands, and the most active of the five volcanoes that together form the island of Hawaiʻ i. Located along the southern shore of the island, the volcano is between 300,000 and 600,000 years old and emerged above sea level about 100,000 years ago. It is the second youngest product of the Hawaiian hotspot and the current eruptive center of the Hawaiian–Emperor seamount chain. Because it lacks topographic prominence and its activities historically coincided with those of Mauna Loa, Kīlauea was once thought to be a satellite of its much larger neighbor. Structurally, Kīlauea has a large, fairly recently formed caldera at its summit and two active rift zones, one extending 125 km east and the other 35 km west, as an active fault of unknown depth moving vertically an average of 2 to per year.
Document 10: Evolution of Hawaiian volcanoes: The fifteen volcanoes that make up the eight principal islands of Hawaiʻ i are the youngest in a chain of more than 129 volcanoes that stretch 5800 km across the North Pacific Ocean, called the Hawaiian-Emperor seamount chain. Hawaiʻ i's volcanoes rise an average of 4572 m to reach sea level from their base. The largest and most famous, Mauna Loa, has built itself up to a height of 4169 m . As shield volcanoes, they are built by accumulated lava flows, growing no more than 3 m at a time to form a broad and gently sloping shape.
Document 11: Hawaiʻi Volcanoes National Park: Hawaiʻ i Volcanoes National Park, established on August 1, 1916, is an American National Park located in the U.S. state of Hawaii on the island of Hawaii. It encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive shield volcano. The park delivers scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of volcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna.
Document 12: Mauna Loa: Mauna Loa ( or ; Hawaiian: ] ; English: Long Mountain ) is one of five volcanoes that form the Island of Hawaii in the U.S. state of Hawaiʻi in the Pacific Ocean. The largest subaerial volcano in both mass and volume, Mauna Loa has historically been considered the largest volcano on Earth. It is an active shield volcano with relatively gentle slopes, with a volume estimated at approximately 18000 mi3 , although its peak is about 120 ft lower than that of its neighbor, Mauna Kea. Lava eruptions from Mauna Loa are silica-poor and very fluid, and they tend to be non-explosive.
Document 13: Kilauea Military Camp: Kīlauea Military Camp (KMC) is operated as a Morale, Welfare and Recreation (MWR) facility on Hawai‘i Island, also known as the Big Island, in Hawaiʻi. It is located inside Hawaiʻi Volcanoes National Park. This U.S. Department of Defense (DOD) facility is at an elevation of 4000 feet, within walking distance from Kilauea Volcano, the world’s most active volcano.
Document 14: Hilina Slump: The Hilina Slump is a 5,000 cubic mile (20,000 kilometre³) section of the Big Island of Hawaii on the south flank of the Kilauea volcano. Between 1990 and 1993, Global Positioning System measurements showed a southward displacement of the south flank of Kilauea up to approximately 10 centimeters per year. The slump has the potential of breaking away at a faster pace in the form of an underwater landslide. In Hawaii, landslides of this nature are called debris avalanches. If the entire Hilina Slump were to slide into the ocean at once, it could cause an earthquake in excess of a 9 in magnitude, and a megatsunami. Previous megatsunamis in Hawaii 110,000 years ago caused by similar geological phenomena may have created waves 1,600 feet (500 m) tall.
Document 15: Detroit Seamount: Detroit Seamount, which was formed around 76 million years ago, is one of the oldest seamounts of the Hawaiian-Emperor seamount chain (Meiji Seamount is the oldest, at 82 million years). It lies near the northernmost end of the chain and is south of Aleutian Islands (near Russia), at It is a seamount in the chain, located north of the hinge of the "V" in the image at right.
