Inactive Volcanoes

Hualalai is located on the main Hawaiian island. The volcano is 8271 feet tall. Hualalai is the westernmost of the five major Big Island volcanoes. Hualalai is an in-active but considered the third-most active volcano after Kilauea and Mauna Loa. Six different vents erupted lava between the late 1700s and 1801. While its in its past shield stage, Haulalai is considered a potentially dangerous volcano that is likely to erupt in the next 100 years. Its summit is fifteen kilometers away from the town of Kailua-Kona and a flow as voluminous as the 1800 eruption could cover that distance in a few hours.

Mauna Kea is the largest mountain in the Hawaiian chain. "Mauna Kea" means "White Mountain." The estimated age of the volcano is one million years. It is located on the main island. The volcano has evolved beyond the shield-building stage, as indicated by the very low eruption rates compared to Mauna Loa and Kilauea; the absence of a summit caldera and elongated fissure vents that radiate its summit; steeper and more irregular topography (for example, the upper flanks of Mauna Kea are twice as steep as those of Mauna Loa); and different chemical compositions of the lava. > Both the volcanoes Mauna Loa and Mauna Kea are so high that snow falls during the winter months, accumulating to a few meters depth. > Presently Mauna Kea is a dormant volcano which hadn't erupted since 4,500 years ago. Despite this, Mauna Kea is likely to erupt again. A swarm of earthquakes beneath Mauna Kea might signal that an eruption could occure within a short time, but such swarms do not always result in an eruptions.
