Why does hawaii have volcanoes

Why does Hawaii have volcanoes but is not on a plate boundary?

Hawaii is geologically a unique place on Earth because it is caused by a ‘hot spot.’ Most islands are found at tectonic plate boundaries either from spreading centers (like Iceland) or from subduction zones (like the Aleutian Islands). Some of these volcanoes build up to the surface of the ocean and become islands.

Why do volcanoes occur in Hawaii?

Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the seafloor, at what is called a “hot spot.” The Hawaiian Islands were formed by such a hot spot occurring in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving.

Are Hawaii Volcanoes dangerous?

They’re very explosive volcanoes because they’re highly charged with gases. And so when they erupt, it’s very destructive. But Hawaiian volcanoes don’t contain a lot of water or other volatiles. Generally speaking, the Hawaiian volcanoes don’t erupt explosively; they produce relatively very slow-moving lava flows.
