The Pyroclastic deposits of Mount Etna volcano, Sicily
Geological Journal, 1987AbstractThroughout most of its geological evolution Etna has been characterized by the eruption of lava flows of a predominantly hawaiitic composition, but within the stratigraphical record there are four major sequences of pyroclastic materials: the Acireale tephra and lahars (˜100000 B.P.); the ‘lower tephra’ and Milo lahars (both ˜26000 B.P.); the ...

Forests in a Changing Environment on the Etna Volcano
1992The changes which have taken place in the environment of the Etna volcano situated in the Mediterranean region, have conditioned the forests of the region in various ways. Volcanic activity has destroyed part of the forests, it has produced a new morphology, and has forced the vegetation to colonize new lava substrata.

A statistical analysis of flank eruptions on Etna volcano
Journal of Volcanology and Geothermal Research, 1985Abstract A singularly complete record exists for the eruptive activity of Etna volcano. The time series of occurrence of flank eruptions in the period 1600–1980, in which the record is presumably complete, is found to follow a stationary Poisson process.

Silicate microspherules intercepted in the plume of Etna volcano
Nature, 1986A possible volcanic origin has been suggested for the micrometre-sized spherules that have been discovered in polar snows or ice-cores1–5, and in the stratosphere6,7. However, although such particles, especially when black and magnetic, have been identified among the tephra deposits of some volcanoes3,8–12, their volcanic emission has never been ...

Mt. Etna volcano: A seismological framework
2004Mount Etna is one of the most active and powerful basaltic volcanoes in the world, with an historical record of documented eruptions going back over 2000 years. It is located in eastern Sicily in a complex geodynamic framework, where major regional structural lineaments play a key role in the dynamic processes of the volcano [e.g., Bonaccorso et al ...

Large ground deformation on Mount Etna volcano
Nature, 1977AN 11-km traverse of benchmarks for precise levelling across the summit of Mount Etna was established and levelled in July 1975. The traverse runs from a reference benchmark near the Piccolo Rifugio (about 2515 m a.s.l.) in the south, across the summit cone (highest station about 3210 m a.s.l.) and down to the rim of the Cratere Ellittico Caldera near ...

Accumulation of fluoride by lichens in the vicinity of Etna volcano
Water, Air, and Soil Pollution, 1988Volcanoes are known to discharge gaseous fluorides to the atmosphere, but measurement of these is difficult, and the dispersion characteristics have not previously been studied in detail. Samples of lichens were collected from the slopes of Etna Volcano in 1985 and 1987, in order to monitor these gases.

An analysis of hazard from Mount Etna volcano
Journal of the Geological Society, 1979The eruptive history of Mt. Etna during the last 400 years is well documented; by assuming that previous activity is representative of that in the future, it is possible to evaluate in a general way the hazard to land and property on different parts of the mountain by lava.

Etna Eruption Puts Volcano Monitoring to the Test
Science, 2001MOUNT ETNA, SICILY-- Etna9s latest eruptions, which began on 17 July, have attracted scores of volcanologists eager to use the latest technologies to study this awesome display. So far, Etna9s pyrotechnics show no signs of abating. As Science went to press, the half-million-year-old volcano9s activity posed little threat to surrounding ...

Selenium around Etna Volcano, Italy
2010Humans are attracted by the fertile properties of volcanic soils and currently around 10% of the world population lives within active volcanic areas. Volcanoes emit significantly amounts of potentially toxic elements such as selenium (Se), even in the absence of obvious volcanic activity.
