Where Does Volcanic Activity Occur? Myth: Most of the Earth's igneous rocks are produced at the Ring of Fire.. Fact: 70% of the Earth's surface is ocean floor, which is made of basalt, an igneous rock produced at mid-ocean ridges. The ridges are the most volcanically active features on the planet. Plate boundary volcanism. Volcanic activity occurs at two types of plate boundaries: mid-ocean ridges and subduction zones. At mid-ocean ridges, basaltic eruptions produce new sea-floor crust. These underwater eruptions don't produce big mountainous volcanoes, which is why they are often overlooked as the most volcanically active features on Earth.
Answers. Best Answer: Basalt eruptions are most prevalent in oceanic eruptions, at sea floor spreading zones and formation of island arcs. Felsic eruptions, which are typically granitic or rhyolytic, are more common in continental eruptions.The predominant eruptions are oceanic, so basaltic eruptions are more common.A theory of the evolution of a volcano maintains that eruptions of young volcanoes start out basaltic and become more and more felsic as the volcano matures. This is thought to be to magma differentiation and fractionation. Source(s):elsic eruptions, which are typically granitic or rhyolytic, are more common in continental eruptions.
