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 island of Hawaiʻi comprises five volcanoes, of which two (Kilauea and Mauna Loa) are still active. Kamaʻehuakanaloa Seamount (formerly Lōʻihi) continues to grow offshore, and is the only known volcano in the chain in the submarine pre-shield stage. [1]
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.

Hualālai is the third most active volcano on the island of Hawaiʻi, behind Kīlauea and Mauna Loa. Although the two larger volcanos have each erupted over 150 times in the last 1,000 years, Hualālai has done so only thrice. Activity seems to recur at the volcano every 200 to 300 years. [12]
Kilauea and Mauna Loa are located in Hawaii Volcanoes National Park on the Big Island of Hawaii. The park is about 30 miles away from Hilo and the nearest airport, Hilo International Airport.
