Metrics details. In recent years, it has displayed enhanced explosive activity, causing concern amongst local inhabitants who frequently have to live with, and clean up, substantial ashfall. However, a previous study by the authors showed the capability of basaltic ash to generate the hydroxyl radical, a highly-reactive species which may cause cell damage. That study investigated a single sample of Etna ash, amongst others, with data giving an early indication that the Etnean ash may be uniquely reactive. In this study, we analyse a suite of Etnean samples from recent and historical eruptions. Given the recent increase in explosivity of Etna, the potential hazard of similarly, or more-explosive, eruptions should be assessed.

Our helicopter hovered like a mayfly just a hundred feet above the southeast crater at the summit of Mount Etna. There was no fire below, only black ash and the yellow brimstone that had formed like a nicotine stain around the wrinkled mouth of the smoking giant. Peering deeper in, all I could see was a swirling fury of gases.

Full day excursion on the summit region of Mt Etna to observe its smoking craters, volcanic phenomena and moonlike landscapes (weather and volcanic activity.
Some of the most exciting and intriguing wines coming out of Italy have one thing in common: the volcanic origins of their soils. While the wines of Mount Etna immediately pop to mind, a surprising number of great wines, from the Veneto down to Sicily, hail from volcanic terroirs. Additionally, many of these grape-growing areas have extremely old vines, some more than years old in parts of Campania and Sicily.
The vineyard altitude, grape varieties and cellar practices all play crucial roles in the final product, but volcanic soils lend structure, longevity and an extra layer of dimension to the final wines. Campania is a captivating and beautiful region in the southwest of the country. Mount Vesuvius, to the east of Naples, last erupted in but is better known for burying Pompeii under up to 20 feet of volcanic ash and pumice in 79 A.
Irpinia is home to native red grape Aglianico, most notable in Taurasi, and white grapes Fiano and Greco di Tufo. While these varieties grow in other areas, they produce savory wines of exceptional longevity here. Fiano di Avellino produces full-bodied white wines, with floral aromas, rich fruit flavors and smoky mineral sensations.

The fumarolic mineralogy of the Icelandic active volcanoes, the Tyrrhenian volcanic belt Italy and the Aegean active arc Greece is investigated, and literature data surveyed in order to define the characteristics of the European fumarolic systems. They show broad diversity of mineral associations, with Vesuvius and Vulcano being also among the world localities richest in mineral species. The situation can be different in the systems that are not recessing but show fluctuations in activity, illustrated by the example of Vulcano where the high-temperature association appears intermittently.
Average HF emission rates from Mt. Etna can be estimated to about 75 impermeable sedimentary rocks especially along the coastline, where considerable amounts of water are periods of intense ash emission, when soluble fluorine salts are adsorbed on ash particles, later deposited has ever been noted up to date.
Honolulu Community College Earth Revealed. Oh, hi! I was just reading here, and I found an interesting quote that I’d like to share with you. Back in , a geologist named Adolph Knopp wrote a passage about geologic time. Knopp wrote “If I were asked as a geologist, what’s the single greatest contribution of the Science of Geology to modern civilized thought,the answer would be the realization of the immense length of time.
So vast is the span of time recorded in the history of the Earth that it’s generally distinguished from the more modest kinds of time by being called “geologic time.

Basalt and volcanic ash are natural constituents of the ground surrounding volcanic areas such as Mount Etna. The dust may be daily inhaled by the general population as well as by several types of workers, such as tourist guides, forest guards, road maintenance workers, dump and construction workers. In some of these occupational areas following the manufacturing process, these materials can be mechanically broken down to small particles, easy to inhale.
One of these occupational areas is the construction one, where basalt and volcanic ash are often excavated in the early construction working phases. Besides, basalt rock, basalt crushed rock locally called azolo and volcanic ash are generally exploited as construction material, usually mixed with cement. Volcanic ash is composed of fragments of pulverized rock, minerals and volcanic glass, produced during volcanic eruptions and measuring no more than 2 mm in diameter 1.
With the word azolo we refer to a specific type of grey-black, sand-like, sharp, less than 2 mm in diameter stone dust of Mount Etna’s area, which derives from the crushing of basaltic rock due either to weathering factors or man’s intervention 2.

Contents: What is Radioactive Dating? Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale. Radioactive dating uses the ratios of isotopes and their specific decay products to determine the ages of rocks, fossils, and other substances. Elements occur naturally in the earth, and they can tell us a lot about its past.
Carbon, uranium, and potassium are just a few examples of elements used in radioactive dating. Each element is made up of atoms, and within each atom is a central particle called a nucleus. Within the nucleus, we find neutrons and protons; but for now, let’s just focus on the neutrons. These neutrons can become unstable, and when they do, they release energy and undergo decay. Scientists call this behavior radioactivity. Radioactivity occurs when the nucleus contains an excess amount of neutrons.
When an atom varies in the number of neutrons, the variation is called an isotope. Isotopes are unstable forms of elements. During radioactivity, the unstable isotope breaks down and changes into a different substance. A new, more stable isotope, called the decay , or daughter product , takes its place.
