   What is an archipelagic apron?

   • An archipelagic apron is a fanlike slope of volcanic rock that forms around groups of ancient or recent islands, most commonly in the central and southern Pacific Ocean. These aprons have a slope of 1° to 2°, with the slope decreasing near the shore. The upper parts of the aprons may be indented by deep-sea channels.

   What is an archipelago made up of?

   • An archipelago is a group of islands closely scattered in a body of water. Usually, this body of water is the ocean, but it can also be a lake or river. Most archipelagoes are made of oceanic islands. This means the islands were formed by volcanoes erupting from the ocean floor. An archipelago made up of oceanic islands is called an island arc.

   Why are most archipelagos made of oceanic islands?

   • Most archipelagoes are made of oceanic islands. This means the islands were formed by volcanoes erupting from the ocean floor. An archipelago made up of oceanic islands is called an island arc. Many island arcs were formed over a single “ hot spot.”

   Do aprons have a noticeable slope?

   • Aprons typically have a slope of 1° to 2°, with the slope decreasing near the shore. Some aprons have noticeable relief, but they are more typically smooth due to a veneer of sediments deposited during the last 10,000 years or so.

   What is an island arc?

   • An archipelago made up of oceanic islands is called an island arc. Many island arcs were formed over a single “ hot spot.” The Earth’s crust shifted while the hot spot stayed put, creating a line of islands that show exactly the direction the crust moved.

   An archipelagic apron is a fan-shaped gently sloping region of sea floor found around oceanic islands, particularly in the south Pacific Ocean. The name was first proposed by Henry William Menard in 1956 because of the resemblance of the slope to an apron.

   Archipelagic aprons are submarine landslide complexes composed of erosion and deposition-al gravity flows that involve both sediment and blocks of the insular flanks. Aprons have been recognized as common bathymetric features on the lower flanks of oceanic islands, seamounts, guyots, and ridges for more than half a century.

   Seismic refraction measurements show that volcanic rocks are kilometers thick in the vicinity of all islands where studies have been made. This material forms the bulk of the archipelagic aprons and buries the pre-existing hilly terrane of the sea floor so as to form a relatively smooth plain.
