The diagram shows the development of the Hawaiian island chain in the centre of the Pacific Ocean.
Overall, the process consists of several distinct stages, including hot spot plume, volcanic development, magma plume, and others. Additionally, the process is a natural one, which requires some time.
To begin with, the eruption process initiates at the Pacific plate, around 2883 kilometers below the Earth’s surface. This is followed by an increase in volcanic activity and a transition into the hot spot plume stage, and then the second stage, characterized by magma. Eventually, the final phase of the volcano is the youngest phase, which develops through a series of eruptions.
The Pacific Ocean contains tectonic plates, with the Pacific tectonic plate moving at an approximate rate of 7 to 9 centimeters per year, which leads to the accumulation of solid, dense rocks. The Hawaiian island chain is recognized as one of the oldest volcanic regions, with its formation dating back around 80 million years.
