Like all Hawaiian volcanoes, Mauna Loa was created as the Pacific tectonic plate moved over the Hawaii hotspot in the Earth's underlying mantle. [10] The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 3,700 mi (6,000 km)-long Hawaiian–Emperor seamount chain. [11]
This is the youngest part of the chain and includes volcanoes with ages ranging from 400,000 years [2] to 5.1 million years. [3] The island of Hawaiʻi comprises five volcanoes, of which two (Kilauea and Mauna Loa) are still active.
The first formed the broad tholeiitic shield volcano of West Molokai that ended 1.89 million years ago. The second volcanic phase produced postshield alkalic volcanics 1.76 million years ago. [ 1 ] There is no evidence for a rejuvenated phase of the West Molokai Volcano, whilst the East Molokai Volcano does.
