What is the most recent eruption of Mount Etna?
Its most recent eruptive period began in September 2013 and more recently has been characterized by Strombolian explosions, ash plumes, lava fountaining, and flows (BGVN 46:04).
What is the flank of the volcano?
Flank – The side of a volcano. Lava – Molten rock that erupts from a volcano that solidifies as it cools.
What volcanoes have flank eruptions?
At some volcanoes, flank eruptions are common, and occur along clearly defined rift zones. This is the case at Mauna Loa and Kilauea volcanoes in Hawaii, Piton de la Fournaise on Reunion Island, and Mount Etna in Italy. Flank and summit eruptions may occur at the same time.
How many eruption has Mount Etna had?
The volcano has experienced more than 200 eruptions since then, although most are moderately small. Etna’s most powerful recorded eruption was in 1669, when explosions destroyed part of the summit and lava flows from a fissure on the volcano’s flank reached the sea and the town of Catania, more than ten miles away.
Where would a flank eruption happen on a volcano?
A flank eruption occurs where the lava-filled fractures intersect the slope of the volcano.
What do you mean by flank?
1a : the fleshy part of the side between the ribs and the hip broadly : the side of a quadruped She gently patted the horse’s flank. b : a cut of meat from this part of an animal — see beef illustration. 2a : side the eastern flank of a volcano. b : the right or left of a formation attacked the enemy on both flanks.
Where do flank eruptions occur?
A flank eruption is a volcanic eruption which occurs on the flanks of a volcano, instead of at its summit. Such eruptions occur when the conduit connecting the summit to the magma chamber below is blocked, forcing the magma to move laterally.

Has Mount Etna erupted in 2021?
Europe’s most active volcano, Mt Etna, has been spewing out lava, gas and ash since February. Italy’s Mount Etna volcano erupted for the 50th time this year over the weekend and the European Sentinel 2 satellite captured the epic view from space.
How many times has Mount Etna erupted since 2000?
Since the year AD 1600, at least 60 flank eruptions and countless summit eruptions have occurred; nearly half of these have happened since the start of the 20th century. Since 2000, Etna has had four flank eruptions – in 2001, 2002–2003, 2004–2005, and 2008–2009.
How far away can you find ash from Mount Etna?
From about 35,000 to 15,000 years ago, Etna experienced some highly explosive eruptions, generating large pyroclastic flows, which left extensive ignimbrite deposits. Ash from these eruptions has been found as far away as south of Rome’s border, 800 km (497 mi) to the north.
How deep is Etna’s volcano?
Experts at the INGV estimate that Etna’s main reservoir, and also its largest, is 12km (7.5 miles) underground. The Sicilian geophysicist Rosanna Corsaro, who studies Etna’s core from INGV headquarters, says: “The magma that’s been surfacing in these recent eruptions seems to come from about 10km underground.”
Where does Mount Etna’s magma come from?
Etna’s magma originates from several reservoirs located miles underground. Experts at the INGV estimate that Etna’s main reservoir, and also its largest, is 12km (7.5 miles) underground.
