is a dormant shield volcano
on the island of Hawaiʻi
in the Hawaiian Islands
. It is the third-youngest and the third most active of the five volcanoes that form the island of Hawaiʻi
, following Kīlauea
and the much larger Mauna Loa
, and also the westernmost. Its peak is 8,271 feet (2,521 m) above sea level
Hualālai is estimated to have risen above sea level about 300,000 years ago. Despite maintaining a very low level of activity since its last eruption in 1801, Hualālai is still considered active, and is expected to erupt again some time within the next century. The volcano has been inhabited for centuries by Hawaiian natives, predating recorded history. The ecologically important volcano is home to many rare species and contains several nature reserves near the summit.
