WebHeat from the Hawaiian hot spot partially melts mantle rock at depths starting about 200-400 km (125-250 mi) below Earth's surface. This melting produces magma that rises upward through the overlying Pacific Plate. As the plate moves west-northwest, each volcano moves with it from its place of origin above the hot spot. WebA seamount will be formed through volcanic activity over the hot spot, then the plate will move and displace the seamount before the hot spot produces the next seamount, and so on. In this way, over time, the seamounts are formed in chains.

A seamount is a large submarine landform that rises from the ocean floor without reaching the water surface (sea level), and thus is not an island, islet, or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
