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]
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.
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 Hawaiʻi hotspot is a volcanic hotspot located near the namesake Hawaiian Islands, in the northern Pacific Ocean.One of the best known and intensively studied hotspots in the world, [1] [2] the Hawaii plume is responsible for the creation of the Hawaiian–Emperor seamount chain, a 6,200-kilometer (3,900 mi) mostly undersea volcanic mountain range.
STORY: The skies of Hawaii’s Big Island turned a hellish bright red on Sunday (November 27) as the world’s largest active volcano, Mauna Loa, began erupting for the first time since 1984 ...
This is a list of volcanic eruptions from Mauna Loa, an active shield volcano in the Hawaiian Islands that last erupted in 2022. These eruptions have taken place from the main caldera and fissures along rift zones.
