Māhukona
From Wikipedia, the free encyclopedia
Māhukona is a submerged extinct shield volcano, with a prominent rift zone to its west. It is located off the northwestern shore of the island of Hawaiʻi and was the first volcano to form part of the island of Hawaiʻi. It is believed to have risen about 250 m (800 feet) above sea level. Māhukona became extinct between the shield and postshield stages about 470,000 years ago and subsided between 435,000 and 365,000 years ago.[1]
