A reef that surrounds a volcanic island is known as a fringing reef. These reefs usually form close to the shoreline and develop on the shallow-water platform around the island. The growth of corals on the fringing reef is influenced by the volcanic activity and the geography of the island.
Coral reefs can take four forms; fringing reef, platform reefs, barrier reefs and atolls. Fringing reefs are narrow and shallow, and generally occur near the shore, they literally are a thin 'fringe' along the coast. Platform reefs are reef outcroppings far from shore that occur in calm water. They often have a shallow lagoon, and are flat on top. Barrier reefs are reefs growing along a coastline that are separated from the coastline by a lagoon. Barrier reefs are very similar to fringings except that they are much larger. Atolls are ring reefs that usually form at the base of a volcano. Over time the volcano dissapears, leaving a rin of reef surrounded by deep ocean.

Fringing Reef
The three types of reefs are fringing reefs, barrier reefs, and atolls. Fringing reefs grow close to the shorelines of islands or continents, barrier reefs are separated by a lagoon from the land, and atolls are circular coral reefs surrounding a central lagoon, often found in the open ocean.

Fringing reefs form very close to the shoreline of a volcanic island. They are the most common type of reef and directly attached to the shore without a lagoon separating them.
An atoll is an island (or islands) of coral that encircles a lagoon partially or completely.
A circular coral island that encloses a lagoon is called an atoll. Atolls are typically formed from coral reefs that grow around the rim of a submerged volcanic island.
