Answer
Volcanoes are found along the weak zones of the earth’s crust where due to continuous tussle by tectonic forces maximum active volcanoes have created. The important volcanic zones of the world are-
Circum-Pacific Belt — The volcanoes occur near the earthquake belts around the young fold mountains. It is also known as 'Pacific Ring of Fire' because over 80% of the total number of active volcanoes are concentrated in this region. Among these are included 40 active volcanoes in Andes, over 100 in the Philippines, 70 in Indonesia and 40 in Japan.
Mid-World Mountain Belt — Mt. Stromboli, Mt. Vesuvius and Mt. Etna are located in the Midworld Mountain Belt. The only active volcano in India, in Andaman and Nicobar Islands is also located in this belt. The Hawaiian Islands, Canary Islands, Mt. Kenya are all in the Midworld Mountain belt.
