Scientists Have Identified World’s Largest Shield Volcano Twice as Big as Former Record Holder

Scientists have suspected that Mauna Loa wasn’t the world’s biggest volcano since as far back as the 1970s, but they haven’t had enough data to confirm their hypothesis. 50 years later they managed to prove that they were right.

Researchers from the University of Hawaii at Manoa named Puhahonu in the Pacific Ocean the largest and hottest shield volcano on Earth. Their study appears in the new volume of Earth and Planetary Science Letters. Puhahonu, which literally means “turtle rising for breath” in Hawaiian, is twice as big as Mauna Loa, the former record holder, which is located on the Big Island of Hawaii. Mauna Loa was long believed to be the largest on Earth. However, after studying the ocean floor along the Hawaiian volcano chain and conducting a chemical analysis of rocks, the scientists withdrew the title and gave it to nearby Puhahonu.

Puhahonu is a shield volcano, which means it is “exclusively basalt, a type of lava that is very fluid when erupted”, according to Oregon State University. Hawaii hosts the most famous shield volcanoes. Moreover, they have been erupting with some of the hottest magma on Earth, the research highlights.

The visible part of Puhahonu has been known as the Gardner Pinnacles, but researchers hope to draw attention to its original name.
