The working explanation boils down to indigestion: how volcanic gases build up inside Etna's underground plumbing. As with all volcanoes, the magma inside Etna holds gas bubbles, such as carbon dioxide, sulfur dioxide and water.

Yes, there are many volcanoes but they are inactive since thousands or million years. Sardinia is the only italian region without seismic risk. Some ancient volcanoes have mantained their craters and their conical shape too. There are also volcanic regions in Sardinia like the Mejlogu region, with also lava fields.

Mount Kinabalu is not an active volcano and neither was it ever a volcano. Basically, it was made from granodiorite, which is an intrusive igneous rock. ... It is relatively young mountain. 6.

Etna is considered to be, on the long-term average, the major atmospheric point source of many environmental harmful compounds. Their emission occurs in the form of gases, aerosols or particulate, both through continuous passive degassing from open-conduit activity and through sporadic paroxysmal eruptive activity.

The movement of tectonic plates has begun to actively split the African plate, forming a rift valley in East Africa[2]. The cracks and fissures of this rift allow magma to extrude upwards, causing volcanic activity and forming volcanoes such as Ol Doinyo Lengai.

Mount Vesuvius is considered to be one of the most dangerous volcanoes in the world because of its proximity to the city of Naples and the surrounding towns on the nearby slopes. The volcano is classed as a complex stratovolcano because its eruptions typically involve explosive eruptions as well as pyroclastic flows.

Mauna Loa is among Earth's most active volcanoes, having erupted 33 times since its first well-documented historical eruption in 1843. It has produced large, voluminous flows of basalt that have reached the ocean eight times since 1868.

Mount Etna consists of two edifices: an ancient shield volcano at its base, and the younger Mongibello stratovolcano, which was built on top of the shield. The basaltic shield volcano eruptions began about 500,000 years ago, while the stratovolcano began forming about 35,000 years ago from more trachytic lavas.

The volcanoes of Iceland include a high concentration of active ones due to Iceland's location on the mid-Atlantic Ridge, a divergent tectonic plate boundary, and its location over a hot spot. The island has 30 active volcanic systems, of which 13 have erupted since the settlement of Iceland in AD 874.

Mount Rainier as seen from the crater rim of Mount St. Helens, overlooking Spirit Lake. Mount Rainier is an episodically active composite volcano, also called a stratovolcano. Volcanic activity began between one half and one million years ago, with the most recent eruption cycle ending about 1,000 years ago.
