Explanation: You can answer that question yourself with the information that the Pacific Tectonic Plate is slowly moving to the North-West and the hotspot that creates the volcanos under the Hawaiian Islands is stationary. This is why the younger Hawaiian Islands are to the South-East of the older Hawaiian Islands.

Why is Kauai The oldest Hawaiian island?
Kauaʻi’s origins are volcanic, the island having been formed by the passage of the Pacific Plate over the Hawaii hotspot. At approximately five million years old, it is the oldest of the main islands.
Which was formed first Hawaii or Kauai?
Magma spewing from a hot spot beneath the floating Pacific Tectonic Plate formed Kauai as it did the other islands in the chain. Kauai is the oldest of the Hawai’ian islands and it is believed the volcano that created Kauai first began erupting some 10 million years ago.
Which Hawaiian island is the oldest and why?
Kauai – With an estimated geological age of 5.1 million years, Kauai is the oldest of the Hawaiian islands. Nicknamed the Garden Isle for its lush landscape, Kauai — like the other Hawaiian islands — was created by a volcanic eruption.
How did Kauai The oldest of the Hawaiian Islands move?
The six largest Hawaiian Islands—the Big Island, Maui, Lanai, Molokai, Oahu, and Kauai—form a chain of islands running to the northwest.In the case of the Hawaiian Islands, the Pacific Plate is continually moving to the northwest over the Hawaiian hot spot. This movement caused the Hawaiian chain of islands to form.
Is Kauai or Niihau older?
According to Hawaiian mythology, Ni’ihau is older than Kaua’i, as the volcano goddess Pele made her home on this island first before moving down the chain of islands ending with Hawai’i. However, geological evidence suggests that Ni’ihau was formed after Kau’i volcano began erupting.
When did Kauai last erupt?
Located along the southeastern shore of the island, the volcano is between 210,000 and 280,000 years old and emerged above sea level about 100,000 years ago. Its most recent eruption began on September 29, 2021.

Which Hawaii island is oldest?
Kaua’i Island
Volcanism on Kaua’i Island ended about 3.8 million years ago, making it the oldest of the main Hawaiian Islands. On the Island of Hawai’i, the youngest of the main Hawaiian Islands, Kīlauea and Mauna Loa are historically the two most active volcanoes, with frequent eruptions.
Is Kauai floating away?
Currently, the island of Kauai is 12 miles NNE from where it was located in 1993. This has resulted in additional fuel costs for shipping and air travel.While this project is expensive, it’s important to stop one of our islands floating away and joining another country.
Where is Kure Atoll?
Northwestern Hawaiian Islands
Kure Atoll is the most remote of the Northwestern Hawaiian Islands, and the northern-most coral atoll in the world. Kure is an oval-shaped atoll, which is 6 miles at its maximum diameter and 55 miles west-northwest of Midway Atoll at the extreme northwest end of the Hawaiian archipelago.
Why is Kauai so green?
Each Hawaiian island is unique in nature due to its specific age in geologic time. Kauai is the oldest of the eight main islands. Wave action, wind and water erosion have carved once cone shaped volcanoes into what Kauai is today, the lush green Garden Isle.
How much older is Kauai than Oahu?
The Hawaiian Islands, by Age
The main islands are positioned in order of age, from oldest to youngest, from northwest to southeast. Kauai is approximately 5.1 million years old, followed by Oahu at 2.2 to 3.4 million years old.
When was Kauai discovered?
January 1778
Captain James Cook is credited for being the first European to discover the islands; he first landed in Waimea, on the west shore of Kauai in January 1778. Cook originally named Hawaii the “Sandwich Islands” after the fourth Earl of Sandwich.
How old is the youngest Hawaiian island?
between 400,000 and 800,000 years old
Why The Big Island Is The ‘Youngest’ Island: The Big Island is somewhere between 400,000 and 800,000 years old – the youngest of any of the Hawaiian Islands. Pay a visit to Hawaii Volcanoes National Park and you can see fresh lava, days, hours and even minutes old.
Are the Hawaiian Islands sinking?
Because the rate of ice melt has been increasing significantly since 1992 and the land is sinking due to a process called subsidence, Hawaii is particularly vulnerable to an increased rate of sea level rise in the future. Click here to learn more about the causes of sea level rise.
Why are the Hawaiian Islands different ages?
The Hawaiian Islands were formed by volcanic activity.
Each island or submerged seamount in the chain is successively older toward the northwest. Near Hawaii, the age progression from island to island can be used to calculate the motion of the Pacific Oceanic plate toward the northwest.
Why is Niihau forbidden?
The island is a pristine, critical habitat for highly endangered species, and one of the most-coveted travel destinations in the world. Niihau (pronounced NEE-EE-HOW) actually became the “Forbidden Island” during a polio epidemic in the Hawaiian Islands in 1952.
