What is the largest subaerial volcano in the Hawaiian - Emperor seamount chain?
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.
Savai'i Savaiʻ i is the largest (area 1700 km) and highest (Mt Silisili at 1,858 m) island in Samoa and the Samoa Islands chain. The island is the fifth largest in Polynesia, behind the two main islands of New Zealand and the Hawaiian Islands of Hawaii and Maui.
