Hualalai volcano, at the western end of the island, is Hawaii's third youngest shield volcano. Three rift zones, dotted with ash cones and splash cones, tend to the north, northwest and SE, and converge about 5 km E from the summit. Hualalai, the third of Hawaii's active shield volcanoes, is located northwest and west of its giant neighbors Mauna Loa and Mauna Kea.
Hualalai
volcano last erupted between 1800-1801, when it produced lava flows from 5 fissure vents that reached the sea and buried Hawaiian villages.The Hualalai began to erupt about 800,000 years ago and broke the surface of the sea about 300,000 years ago. The volcano has 3 rift zones, the most prominent being the northwest rift, which is about 40 km long and continues into the sea to a depth of 3000 m. For additional information on Hualalai volcano, visit the USGS Hawaiian Volcanic Observatory (Hualalai) page. Hualalai is the westernmost shield volcano on the island of Hawaii.
There was also a protective volcano around Hawaii called Kilauea and Mount Mauna Loa at that time. A network of Hawaiian-Emperor seamounts that extends 6,000 km (3,700 miles) and is more than 70 million years old, recently confirmed by volcanoes on the Hawaiian Islands, seems to originate during this period. In terms of activity, it ranks third in Hawaii's next five volcanoes, after Klauea and Mauna Loa as the largest and most active of them.
North Kona Fall The North Kona depression is a landslide feature located on the western flank of Hualalai volcano. Alkaline eruptions in Hualalai have generally been much less explosive than those at neighboring Kohala and Mauna Kea volcanoes. The Haleakala VOLCANO, or “the house of the sun”, is located in eastern Maui, near the Hawaiian volcano Haleakala. This also presents a clear danger to the surrounding communities; for example, in the event of an eruption similar to that of 1801, Kailua-Kona, which is 15 miles (24 km) from the summit of the volcano, could be completely covered in a matter of hours.
You can enjoy much more of the big island of Hawaii if you travel to Kilauea or Mauna Loa, two of the most popular volcanic destinations. During shield construction (basically the creation and discharge of earth-moving basalt) in Hawaii and other continents, this type is extremely rare.
