Hualalai

The Big Island of Hawaii was formed entirely by volcanic activity. There are five separate volcanoes on the Island. One of those is Hualalai. Hualalai is part of Hawaii Volcanoes National Park Island of Hawaii. This volcano is on the western side of the Big Island and is the third youngest volcano. It is also the third most active volcano on the island.

It was most active in the 1700s. In fact six different vents erupted with lava during that century. Two of the vents produced lava flows that went as far as the sea. The Kona International Airport was built on the larger of the two lava flows. There are several homes, businesses and roads that go up the flows of Hualalai.

It is a bit worrisome that all of this has been built up when the volcano is still active. It is said that in the next 100 years the volcano will most likely erupt again, which would cause a lot of devastation to the homes, businesses and roads maintained today.

The oldest volcano on the Big Island is Kohala, which emerged from the sea roughly 500,000 years ago. All of the volcanoes can be seen during hikes of the national park.
