The given illustration presents information on the Hawaiian Island Chain centre of the Pacific Ocean. As is observed from the diagram, the Hawaiian island chain directly affects the Pacific tectonic plate and because of it, this plate shifts around 7-9 centimetre per year.
As is observed from the graph, below the Pacific Ocean, the Hawaiian island chain stands as several volcanos which are almost 80 million years old. These volcanos stand over the Pacific plate and the eruptions of these volcanos’ created a new volcano just over the Magna spume. The Pacific plate is situated on solid dense rock and because of the new volcano development; the hot spot spume remained static. The eruption process of the volcano’s starts from as deep as 2800 km and that has spat the solid rock layer.
Major islands within 100 km of this area are Maui, Molokai, Oahu and Kauai and because of the eruption and sliding of the plates, the centre of the Pacific Ocean is ever changing.
