Volcanic Hazards and Monitoring Although 200 years have passed since the last Hualalai eruption, it is almost certain that it will erupt again. We cannot say when Hualālai will erupt, but we can offer clues as to the nature of its next eruption. As mentioned above, Hualalai is the third most active volcano after Mauna Loa and Kilauea. In the past 1000 years, Hualalai volcano has been reported to have erupted at least three times.
Volcanologists believe that Hualalai has a recurrence interval of around 200 to 300 years depending on its volcanic activity. According to records, Hualalai last erupted in 1801 after remaining dormant for more than two thousand years. Scientists, therefore, consider Hualalai to be potentially active, as it is expected to erupt again in the next 100 years. Studies have revealed that the volcanic eruption of 1801 produced fluid flows of alkaline basaltic lava with a total production volume of more than 300,000,000 cubic meters.
The huge lava flows released by the two vents eventually entered the Pacific Ocean from the western edge of the Big Island of Hawaii. Hualalai is considered the third youngest and is the westernmost of the five major volcanoes of the Hawaiian Islands. There are six volcanoes in the state that are considered active Kilauea, Mauna Loa, Hualalai and Mauna Kea on the island of Hawaii, Haleakala in Maui and the Loihi Seamount and HVO monitors them all because they have shown signs of activity in the past 10,000 years, Kauahikaua explains. Hualalai is Hawaii's fourth highest mountain peak, rising to a height of 2,521 m and has a prominence of 936 m.
Mauna Loa has not erupted since 1984, making it the volcano's longest calm period in recorded history. . Since it was discovered in 1801, Huallai has been the third most active volcano on the island of Hawaii, but it typically erupts two or three times every 1000 years ago.
A significant part of the southern slope of Hualalai is covered by a layer of volcanic ash 10 to 100 cm thick. This eight-671-foot volcano (commonly known as the 'Hualalai' volcano) on the island of Hawaii is located in the northwest of the island of Hawaii, Hawaii, U.
