1. The ages of rocks from several locations in the Hawaii chain of islands demonstrate that the islands get older as they move northwest, with the Big Island (Hawaii) being the youngest at less than 0.7 million years old and continuously developing.

The notion of a tectonic plate sliding slowly across a hotspot explains this tendency."

2. The next Hawaiian eruption should erupt east or south of the Big Island. There is plenty of indications that such a potential volcano exists on a seamount around 20 miles from the coast.

3. Along the plate borders, chains develop. They are in a parallel  line.

4.The Hawaiian Islanders are thought to have formed and continue to form as a result of recurrent volcanic explosions hundreds of feet beneath the ocean.

These volcanoes' summits can be seen as visible islands. Volcanoes develop when tectonic plates meet or in the center of the plate caused by the movement of plate tectonics, which make up the Upper mantle crust. A hot point in the center of the Pacific Plate created the Hawaiian Island nation in this example.
