Evolution Of Hawaiian Volcanoes
The fifteen volcanoes that make up the eight principal islands of Hawaiʻi are the youngest in a chain of more than 129 volcanoes that stretch 5,800 kilometres (3,600 mi) across the North Pacific Ocean, called the Hawaiian-Emperor seamount chain. Hawaiʻi's volcanoes rise an average of 4,572 metres (15,000 ft) to reach sea level from their base. The largest and most famous, Mauna Loa, has built itself up to a height of 4,169 metres (13,678 ft). As shield volcanoes, they are built by accumulated lava flows, growing no more than 3 metres (10 ft) at a time to form a broad and gently sloping shape.
Hawaiian volcanoes all follow a specific pattern of eruption, building, and erosion. Hawaiian islands undergo a systematic pattern of submarine and subaerial growth that is followed by erosion. An island's stage of development reflects its distance from the Hawaiʻi hotspot.
