How is Mount Etna formed?
Most of the surface of Mount Etna is covered by historic lava flows dating back to eruptions as old as 300,000 years. Scientists believe Mount Etna started as a submarine volcano that gradually grew to stand above sea level on layer upon layer of solidified lava.
What type of rock is Mount Etna made of?
basalt
Mount Etna is an active stratovolcano located at the eastern coast of Sicily which is composed mainly of basalt. Its formation began at about 0.5 Ma when submarine volcanism occurred at the Gela foredeep and formed tholeiitic pillow lava.
Is Mount Etna composite?
Composite volcanoes are steep-sided and cone-shaped, made up of layers of ash and lava and containing sticky lava which doesn’t flow very far. Mount Etna in Italy is a composite volcano. Shield volcanoes have gently sloping sides and runny lava that covers a wide area.
How many craters does Mount Etna have?
four
Today, Mount Etna has four summit craters, dozens of cinder and lava cones on its flanks and the debris of frequent pyroclastic flows of gas, ash and lapilli.
Has Mount Etna killed anyone?
A study on the damage and fatalities caused by eruptions of Etna in historical times reveals that only 77 human deaths are attributable with certainty to eruptions of Etna, most recently in 1987 when two tourists were killed by a sudden explosion near the summit.
What did Mount Etna destroy?
In November 1928 there was an eruption of Mount Etna, Sicily, which led to lava largely destroying the town of Mascali, situated low on the eastern flank of the volcano.

Is it safe to visit Mount Etna now?
During the eruption period, the highest part of the volcano is usually closed to tourists. However, Mount Etna is huge, so even if there are explosions at the height of the summit craters, you can safely hike the lower parts of the volcano.
Is it safe to visit Mount Etna?
Mt. Etna sits closest to the city of Catania, yet on a clear day the volcano is visible from well over half of Sicily. Counterintuitively, they also make it a very safe volcano to visit. Without major buildups up lava and gas, eruptions tend more toward lava flows as opposed to massive explosions.
How safe is Mount Etna?
Are all eruptions dangerous? Etna produces both terminal or subterminal eruptions whose flows cannot reach the inhabited centres because they cool down before reaching them, and lateral eruptions during which eruptive mouths can be opened along the slopes of the volcano, and for this reason they are the most dangerous.
Can you outrun lava?
Could I outrun the lava and make it to safety? Well, technically, yes. Most lava flows — especially those from shield volcanoes, the less explosive type found in Hawaii — are pretty sluggish. As long as the lava doesn’t find its way into a tube- or chute-shaped valley, it will probably move slower than a mile per hour.

What kind of eruption does Mount Etna have?
The volcano’s slopes currently host several large calderas which formed when the roofs of magma chambers collapsed inward, including the east-facing, horseshoe-shaped Valle de Bove. Etna’s current activity consists of continuous summit degassing, explosive Strombolian eruptions, and frequent basaltic lava flows.
