Hawaii is not just one volcano, but a chain of volcanoes, and they are all shield volcanoes.

Here's why:

* Shield volcanoes are characterized by their broad, gently sloping shape, resembling a warrior's shield.

* They are formed by highly fluid, basaltic lava flows that spread out over large areas.

* The Hawaiian volcanoes are known for their effusive eruptions, where lava flows out slowly and steadily rather than explosively.

So, while Hawaii is a volcanic island chain, the individual volcanoes that make up the islands are all shield volcanoes.
