Scientists at the University of Hawaii in Manoah have proven that appearance can be deceptive.
Scientists surveyed the ocean floor and using quantitative modeling determined that the volcano, which is about 171 miles long and 56 miles wide, is twice the size of the Mauna Loa.
According to the survey, “Pahnu is huge” is the reason why it is sinking the earth’s crust.
Michael Garcia, the study’s lead author, told CNN, “The rapid loading of the crust could cause it to shrink.” “When a giant volcano is formed, the heated mantle can flow away from the weight and the volcano can sink.”
Located about 1000 kilometers northwest of Honolulu, Pahanu’s name translates to “turtle surfing for wind” in Hawaiian. The small peaks above sea level are also known as “Gardner Pinclusks”.
The American whale maroon first saw Pahanhunu in 1820, and the crew of a Russian ship first landed on it in 1828. The volcano is now part of the Papahanamokueka Marine National Monument, founded in 2006.
A 1974 survey, based on limited survey data, found Pahunhu to be the largest volcano in the Hawaiian-Emperor chain. Subsequent surveys, which verified both the top and bottom of the ocean floor, concluded that Mauna Loa was the largest volcano. Concluding that the current study updates.
Pahanu is not only the largest volcano in the world, it is also the hottest. The two things are interconnected, Garcia said.
Garcia told CNN, “Volume and temperature go together. Large amounts of hot come from hot magma.
Analysis of volcanic-sampled rocks was used to determine the temperature of the magma, and it was found to be about 1,700 degrees Celsius (3,092 degrees Fahrenheit).
“The discovery of the world’s largest ieldal volcano in the 21st century is a surprising discovery, but then we can learn more about the surface of Mars than the bottom of the Earth’s ocean,” Garcia told CNN.
“We’re still discovering things about our physical planets that we didn’t know. We still have a lot to learn about planet Earth.”
