The Five Volcanoes of Hawaii Island

The Island of Hawaiʻi (Big Island) comprises five shield volcanoes (oldest to youngest):

1. Kohala – Extinct, deeply eroded, northern tip.
2. Mauna Kea – Dormant, highest summit (13,803 ft), world-class astronomy.
3. Hualālai – Dormant (last erupted 1801), western slope.
4. Mauna Loa – Active (last erupted 2022), largest subaerial volcano on Earth.
5. Kīlauea – Highly active (almost continuous 1983–2018, 2020–2023), southeastern flank.

A sixth, Lōʻihi Seamount, grows underwater off the southeast coast—future island.
