What is the second highest mountain in Hawaii, located on the Big Island?

Mauna Loa holds the distinction of being the second highest mountain in Hawaii, situated on the Big Island. Standing at approximately 13,681 feet (4,170 meters) above sea level, it is known for its massive size and volume, making it one of the largest volcanoes in the world. Mauna Loa's most recent eruption was in 1984, and it remains an active volcano, contributing significantly to the geological landscape and volcanic activity of the region.

Mauna Kea, while taller at about 13,796 feet (4,207 meters), is the highest mountain in Hawaii. Kohala and Hualalai are both less prominent in height compared to Mauna Loa. Kohala, at about 5,480 feet (1,669 meters), is considered an older and now dormant volcano, while Hualalai stands at approximately 8,271 feet (2,521 meters) and is also an active volcano, but not as towering as Mauna Loa. Thus, Mauna Loa's relative height and status as the second highest mountain make it the correct choice.
