Hot Spots and Supervolcanoes
Sometimes the movement of tectonic plates creates other geological formations.
Hot spots and supervolcanoes are created as magma rises from the mantle of the Earth, creating volcanic activity.
Hot spots and supervolcanoes do not always occur at tectonic plate boundaries.
Volcanic Hot Spots
Hot spots are stationary (non-moving) plumes of magma that create volcanic activity. As tectonic plates move above a hot spot, lava plateaus, and volcanic islands or seamounts (underwater mountains) may form.
Look at the map of Hawaia above. The Hawaiian Islands were formed by a hot spot in the middle of the Pacific Ocean.
As the plate above the hot spot moved, the hot spot did not move, and that volcanic activity created each Hawaiian island we know today.
In the future, another island in the Hawaiian chain will form as the plate continues to move!
Supervolcanoes
Supervolcanoes are volcanoes that have the potential to produce enormous volcanic eruptions that spew magma and ash over large distances in a very short period of time.
Supervolcanoes usually form at convergent plate boundaries, but not always.
They are more rare than normal volcanoes, but much more powerful and destructive. Their eruptions can have global impacts!
