Hualālai is an active volcano on the island of Hawaii, in the Hawaiian Islands. It is the westernmost, the third youngest and the third most active of the five volcanoes that form the island of Hawaii, after Kilauea and the much larger Mauna Loa. Its peak is located at 8, 271 feet above sea level. For additional information on Hualalai Volcano, visit the USGS Hawaiian Volcano Observatory (Hualalai) page.
No magma-related seismicity or soil deformation has been detected recently in Hualalai, making it difficult to say if and when the next eruption could occur. Although 200 years have passed since the last Hualalai eruption, it is almost certain that it will erupt again. 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. Despite maintaining a very low level of activity since its last eruption in 1801, and having been unusually inactive for the past 2000 years, Hualālai is still considered to be active and is expected to erupt again sometime in the next century.
Hualalai, Mount Hualalai, Hualalai Mountain or Hualalai Volcano: it's just one name, Hualalai. 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. However, in 1929 an intense earthquake swarm hit Hualalai for a period of one month, which has been interpreted as due to an intrusion of magma near the surface, without a superficial eruption. For residents of the Kona area, keep in mind that Hualalai hasn't erupted since 1801; Mauna Loa is considered active but hasn't erupted since 1984. Alkaline eruptions in Hualalai have generally been much less explosive than those at neighboring Kohala and Mauna Kea volcanoes.
