Hualālai last erupted in 1801 and, more recently, had a damaging seismic swarm in 1929 that was probably the result of a superficial magma intrusion. Our editors will review what you submitted and determine if they should review the article.
Hualalaiis one of five active shield volcanoes in the Hawaiian Islands that form the Big Island of Hawaii. This large shield volcano is located in the northwestern part of the Big Island of Hawaii, in the US state of Hawaii.
Hualalai is Hawaii's fourth highest mountain peak, rising to a height of 2,521 m and has a prominence of 936 m. It is also the third most active volcano after Kilauea and Mauna Loa on the island of Hawaii. Geological studies have revealed that over the past 5,000 years, a significant part of the Hualalai volcano's surface has been covered by lava flows formed by alkaline basalt shield. Studies have revealed that the volcanic cone is made up of trachyte, which is only found in the Hualalai volcano and not in any other volcano that forms the island of Hawaii.
Volcanologists believe that Hualalai has a recurrence interval of approximately 200 to 300 years depending on its volcanic activity. Hualalai's west coasts are also ideal for resorts, including the Kona Village Resort, Four Seasons Resort, etc. Hualalai's most important secondary feature is Pu'u Wa'awa'a, a 372 m high volcanic cone located north of the summit with a diameter of more than 1.6 km. last erupted in 1801 after remaining dormant for more than two thousand years.
Lava flows from Hualalai and Kohala volcanoes (along with coral deposits) have buried most of Mahukona volcano. For additional information on Hualalai Volcano, visit the USGS Hawaiian Volcano Observatory (Hualalai) page. The Pohakuloa training area, located on a high plateau between the Hualalai, Mauna Loa and Mauna Kea volcanoes, provides a remote training ground for the United States Army and the U.S. UU.
Lava flows represent by far the greatest danger in a possible future Hualalai eruption, because although explosive pyroclastic eruptions have occurred during the Holocene epoch (the last 10,000 years), they are relatively rare and cover only limited parts of the volcano. During this period, no microearthquake swarms or harmonic tremors (both indicative of magma migration) have been recorded, although Hualalai experiences several magnitude 4 earthquakes each year. Hundreds of years ago, the “Ahu A Umi Heiau” shrine was built on a dry plateau east of Hualalai. Therefore, Hualalai volcano is relatively rougher in shape and structure compared to the active Mauna Loa and Kilauea volcanoes.
In the past 1000 years, Hualalai volcano has been reported to have erupted at least three times.
