Why is Mauna Loa sometimes referred to as the biggest mountain on Earth
and Mauna Kea the tallest?
Mauna Loa has the greatest volume of any volcano, 10,200 cubic miles
(42,500 cubic kilometers) on Earth. Both Mauna Loa and Mauna Kea rise
30,000 feet (10 km) from the sea floor, nearly the elevation of Mt.
Everest.
