Researchers turn to specific volcanoes such as Etna in Sicily to gain insight into volcanic and non-volcanic activities of the Earth. By Fiona Boni, Science Writer A professor at the University of Roma Tre, Valerio Acocella focuses his research on understanding what triggers eruptions and what causes the propagation of the magma to the earth’s surface. He has a special interest in advancing what we know about the structure and pre-eruptive behaviour of the most disruptive type of volcanoes, known as calderas. These are large volcanic depressions formed when a magma chamber is emptied by a volcanic eruption. “Knowledge and prevention are the essential ingredients to mitigate risks,” says Acocella. “Understanding how calderas work is important when forecasting volcanic activity, and also in forecasting large eruptions.” Using similar mechanisms that have been used in studying calderas, Acocella and his team are now also trying to understand and forecast eruptions in composite volcanoes, such as Etna, using a combination of tools. “Volcano Etna has had some interesting eruptions in the last decades. In close collaboration with colleague Marco Neri (INGV Catania), we have been researching how this volcano works along with other processes that are really aren’t strictly volcanic, such as the instability of the volcano flank,” he explains. Based on […]

by Simon Watt, Frontiers Science Writer One vent just isn’t enough for some volcanoes: the curious case of Mount Etna’s wandering craters. Volcanoes are geology at its most exciting. They seem so fiery, dangerous and thrillingly explosive. That may be true, but most old and mature volcanoes are surprisingly stuck in their ways and even if when they will blow is difficult to forecast, where they will blow from is often more predictable. The majority of volcanoes look as they do in a child’s drawing; like a steep mountain with its head cut off. They have a summit crater and, if they erupt, it is from this rocky orifice that lava and ash spews. But this is not the case with Mount Etna on the Island of Sicily, Italy, a study published in the open-access journal Frontiers in Earth Science found. Etna has been collecting new summits as though they are Pokémon. It is as if the mountain has had an outbreak of acne, with multiple cones forming in a geologically short space of time. According to Professor Valerio Acocella, of Roma Tre University and his colleagues from Ingv Catania, this makes Etna “perfect for study”. Valerio and […]
