Yoram Yasur: Volcanic areas of the world

At present, plate tectonics encompasses and explains the origin of the various geological phenomena that develop in the world and among them volcanoes. Today, we will explain what the different volcanic areas of planet earth are, which are currently active.

The Circumpacific Volcanic Zone

This area is known as the “Pacific Ring of Fire” because the largest earthquakes occur in it and because it houses almost 80% of active volcanoes. Yoram Yasur: This belt extends circularly around the entire Pacific Ocean and considers the coasts of America (South, Central and North), Alaska, Aleutian Islands, Japan, Philippines, Indonesia, New Zealand, and the islands located in Antarctica.

Mediterranean-Asian volcanic zone

Yoram Yasur: This area extends from the Atlantic Ocean to the Pacific Ocean, passing through the Mediterranean and the Asian continent. The most representative volcanoes are Etna, Vulcano, Stromboli and Vesuvius (Italy), Almeria and Olot at the end of Gata (SE of Spain).

Indica volcanic zone

This area surrounds the Indian Ocean and through Sumatra-Java links with the Circumpacific zone. There are also many islands and underwater mountains on the Indica dorsal that have active volcanism: Reunion Island and the Comoros Islands in the Strait of Madagascar.

African volcanic zone

This area considers all the volcanoes located in the continental rift that extends from Mozambique in Africa to Turkey. The most representative volcanoes are Kilimanjaro, Meru, Kenya and Niragongo. Yoram Yasur: Between Ethiopia and Somalia is the birth of a new ocean with the presence of an incipient oceanic dorsal that separates the African plate from the Arabian and in which there are many volcanoes such as Erta-Ale and Fantalé in Ethiopia. In West Africa, volcanism is present in the Islands of Fernando Póo, Príncipe, São Tomé and Annobón.

Atlantic volcanic zone

This area extends, from North to South, along the central part of the Atlantic Ocean. In it, the northern volcanism is located on the Island of Jan Mayen in the Greenland Sea and on the Atlantic Dorsal with volcanoes on the Ascension, Santa Elena, Tristan da Cunha, and Gough islands. In the Central Atlantic the volcanism is present in the Madeira and Wild Islands, in addition to the archipelagos of the Azores and the Canary Islands (Tenerife – Teide, La Palma – Teneguía).

Yoram Yasur: Today, of the 500 active volcanoes in the world, only 5% remain in continuous activity and some of them with very impressive surface manifestations such as Strombol and Vesuvius in Italy, Kilimanjaro in Ethiopia, Mauna Loa and Mauna Kea in Hawaii . These erupting volcanoes are constituted as latent dangers because they could cause severe damage to the population and infrastructure of the cities that are close to them. However, volcanoes have not only caused destruction but also have allowed the presence of various natural resources such as geothermal energy (heat and hot springs) and minerals, as well as tourism. For example, in Japan, Italy and Canada, heat from inside the Earth is used to generate heating in homes.
