Hawaii hotspot - Wikipedia
The large difference between the youngest and oldest lavas between Emperor and Hawaiian volcanoes indicates that the hotspot's velocity is increasing. For example, Kohala, the oldest volcano on Hawaiʻi island, is one million years old and last erupted 120,000 years ago, a period of just under 900,000 years; whereas one of the oldest, Detroit ...

Kohala, at the northwestern corner of the island, is the oldest, having ceased eruptive activity about 120,000 years ago. The second oldest is Mauna Kea, which last erupted about 4,000 years ago; next is Hualälai, which has had only one eruption (1800-1801) in written history.
What happened to the age of the Hawaiian Islands moving away
Jun 20, 2024 · The Hawaiian Islands have different ages, with the oldest being approximately 5.1 million years old. The islands get progressively older as you move from southeast to northwest along the island chain. What is Hawaii’s youngest island? The youngest island in the Hawaiian Island chain is the Big Island, also known as Hawai’i.

Oct 19, 2023 · The oldest of the major Hawaiian Islands, Kauai, doesn’t have any active volcanoes because it’s no longer over the Hawaiian hot spot. Instead, the dominant ecological process occurring there is erosion, which has sculpted Kauai’s landscape into beautiful cliffs.

The progressive northwesterly drift of the islands from their point of origin over the hot spot is well shown by the ages of the principal lava flows on the various Hawaiian Islands from northwest (oldest) to southeast (youngest), given in millions of years: Kauai, 5.6 to 3.8; Oahu, 3.4 to 2.2; Molokai, 1.8 to 1.3; Maui, 1.3 to 0.8; and Hawaii ...

And the youngest island is the 'Big Island' of Hawaii itself, with surface lavas all less than one million years old. It still has active volcanism. On the seafloor 20 miles to the southeast of Hawaii is an active volcanic area with periodic eruptions.
the Hawaiian hotspot, magma periodically erupts to form volcanoes that become islands. The oldest island is Kure at the northwestern end of the archi-pelago. The youngest is the Big Island of Hawaii at the southeastern end. Loihi, east of the Big Island, is the newest volcano in the chain and may eventu-ally form another island.

Over the past 70 million years, the combined processes of magma formation, volcano eruption and growth, and continued movement of the Pacific Plate over the stationary Hawaiian "hot-spot" have left a long trail of volcanoes across the Pacific Ocean floor.
