Hawaii is a chain of volcanic islands. Volcanic activity is what formed the islands.
Under the Pacific Ocean where Hawaii is located is what is known as a volcanic hot spot. Magma erupted from under sea volcanoes as the tectonic plate moved over the hotspot forming sea mounts (islands under the sea). When these sea mounts broke the surface they became the Hawaiian islands. The hotspot under Hawaii is still active causing the volcanoes on the big sland to continue to erupt.

Actually, Hawaii has many volcanoes because Hawaii is over a hot spot. A hot spot is a place where heated rocks rise from the mantle in plumes, or thin columns. Volcanoes often develop above the plume. Although most hot spots occur far from plate boundaries, they offer a way to measure plate movement. This is because a hot spot generally stays in one place while the tectonic plate above it keeps moving.
At a hot spot, the heat from the plume partly melts some of the rock in the tectonic plate above it. Magma formed in this way can rise all the way through the plate. If the plate stays over the hot spot long enough, the rock above it will melt and a volcano will form at the surface of the plate.
After repeated eruptions, a hot-spot volcano that forms on the ocean floor may become high enough to rise above the sea as an island. For example, the Hawaiian Islands are being built as the Pacific plate moves slowly over a hot spot.
When the plate moves on, it carries the first volcano away from the hot spot. Heat from the plumes will then melt the rock at a new site forming a new volcano.
Many hot spots have a fixed point that scientists can use to measure the speed and direction of plate movements. For example, the Yellowstone hot spot under the North American Plate has formed a chain of inactive volcanoes. Scientists estimate that the North American plate is moving southwest at about 2.3 cm (1 in.) per year.

Are volcanoes located in the center plates?
Not usually. Most volcanoes are located near plate boundaries, but some volcanoes at hot spots do form in the middle of plates. A few include the volcanoes of Hawaii, the volcano at Yellowstone, and the Volcanoes of the Canary Islands.
Were can hotspot volcanoes be located?
The most famous hot spot volcano is Hawaii as all the Hawaiian islands were formed by them.
What region of the US has the most active volcanoes?
Hawaii has the most active volcanoes in the United States.
The broad slightly dome-shaped volcanoes of Hawaii are?
Most volcanoes in Hawaii are active, meaning that they still erupt. Volcanoes that are not active are referred to as dormant.
Where are the Hawaiian Volcanoes?
The islands are located on the Pacific tectonic plate. Two currently active volcanoes are located on the Big Island, Kilauea, and Mauna Loa. Historical eruptions in Hawaii have occurred at Kilauea. Mauna Loa, Loihi, Hualalai, Haleakala, and two unnamed undersea locations.
