The Continuing Eruption of Mt. Etna
Mount Etna is an active stratovolcano on the east coast of Sicily, Italy, in the Metropolitan City of Catania, between the cities of Messina and Catania. It lies above the convergent plate margin between the African Plate and the Eurasian Plate. It is the tallest active volcano in Europe, currently 3, m high, though this varies with summit eruptions.
“That didn’t seem too bad, but it was really the second explosion that threw up all of those boiling rocks.” “You have to remember that magma is.
It lies above the convergent plate margin between the African Plate and the Eurasian Plate. This makes it by far the largest of the three active volcanoes in Italy , being about two and a half times the height of the next largest, Mount Vesuvius. Mount Etna is one of the world’s most active volcanoes and is in an almost constant state of activity. The fertile volcanic soils support extensive agriculture , with vineyards and orchards spread across the lower slopes of the mountain and the broad Plain of Catania to the south.
Due to its history of recent activity and nearby population, Mount Etna has been designated a Decade Volcano by the United Nations. In Latin it is called Aetna. It is also known as Mungibeddu in Sicilian and Mongibello or Montebello in Italian the Italian word literally means “beautiful mountain”. According to another hypothesis, the term Mongibello comes from the Latin Mulciber qui ignem mulcet , “who placates the fire” , one of the Latin names of the Roman god Vulcan.
Today, the name Mongibello is used for the area of Mount Etna containing the two central craters , and the craters located southeast and northeast of the volcanic cone. The name Mongibel is found in Arthurian Romance , as the name of the otherworld castle or realm of Morgan le Fay and her half-brother, King Arthur , localised at Etna, according to traditions concerning them derived from the stories told by the Breton conteurs who accompanied the Norman occupiers of Sicily.
What were originally Welsh conceptions concerning a dwarf king of a paradisal , Celtic underworld became attached to the quasi-historic figure of Arthur as “Ruler of the Antipodes ” and were then transplanted into a Sicilian milieu, by Bretons impressed by the already otherworldly associations of the great, volcanic mountain of their new home. Mediaevalist Roger Sherman Loomis quotes passages from the works of Gervase of Tilbury and Caesarius of Heisterbach dating from the late twelfth century featuring accounts of Arthur’s returning of a lost horse which had strayed into his subterranean kingdom beneath Etna.
Caesarius quotes as his authority for the story a certain canon Godescalcus of Bonn, who considered it a matter of historical fact of the time of Emperor Henry ‘s conquest of Sicily circa

The main magma source for eruptions on Etna Italy is poorly constrained. For the past four centuries the average magma volume leaving the chamber during each eruption is estimated at 0. From the theory of poroelasticity the estimated chamber volume is then between 69 and km 3. The elastic strain energy stored in the host rock during inflation of such a chamber is about 2. Volcanoes are open thermodynamic systems: they exchange energy and matter with their surroundings.
In particular, volcanoes receive heat and magma from their source chambers.

Because radiometric dating utterly refutes their biblical interpretations, young-Earth creationists YECs are desperate to undermine the reality of these methods. As part of their efforts, YEC Dr. Austin et al. Austin’s conclusions on this project are summarized at the ICR website. The ‘research’ efforts of Austin and his colleagues and their ‘expertise’ in radiometric dating have been widely criticized, including by Joe Meert also here , Karen Bartelt and company and myself at No Answers in Genesis and in my web debate with Dr.

Geological evolution of Mount Etna. The following is based largely on two recent publications see below and has additional information from other sources which are indicated in the text. Gillot, P. Acta Vulcanologica, 5: Tanguy, J. Prelude: Volcanism on the Hyblean Plateau Volcanism in eastern Sicily has occurred episodically since the middle Triassic, producing voluminous mafic that is, silica-poor lavas and clastic fragmental material, much of which was erupted and deposited below the sea level.
The sites of volcanic activity were located in the southeastern part of Sicily, on the Hyblean Plateau Monti Iblei , an area uplifted tectonically during the late Pliocene and Pleistocene. A notable feature of this volcanism was the brief duration of each eruptive event maybe a few years to several centuries and the lack of major volcanic edifices, all activity occurring from regional fissures controlled by the predominant tectonic trends WSW-ENE.
The products of the most recent episodes of Hyblean volcanism lie buried under hundreds of meters of late Pleistocene and recent alluvial sediments, and their precise age is not known, but it appears that there is a more or less continuous series of volcanics becoming progressively younger towards north. On the northern margin of the Catania Plain, an area of tectonic subsidence covered with fluvial deposits between Etna and the northern Hyblean Plateau margin, volcanic rocks outcrop again, but these are considerably younger than those of the Hyblean Plateau and are generally considered the earliest manifestations of volcanism in the Etnean area.
First phase: “pre-Etnean” Volcanic activity in the Etnean area began around 0. This initial activity, the first of four main phases during the evolution of Etna, was very similar in character to the latest Hyblean volcanism, and its products were mainly submarine lavas and volcaniclastics of tholeiitic composition for more info of this type of basaltic rock, see “The life stages of Hawaiian volcanoes” from Volcano World, and the geochemistry page about Loihi volcano, Hawaii.
The famous outcrops of Acicastello, a town some 10 km north of Catania, and nearby locations contain pillow lavas and hyaloclastites produced by this early activity.

Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds for example, Arndts and Overn ; Gill but such attempts invariably have fatal flaws see Dalrymple ; York and Dalrymple Other creationists have focused on instances in which radiometric dating seems to yield incorrect results.
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze for example, Woodmorappe ; Morris HM ; Morris JD Only rarely does a creationist actually find an incorrect radiometric result Austin ; Rugg and Austin that has not already been revealed and discussed in the scientific literature.
The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.

Why does Mount Etna keep erupting? It has a bad case of gas
Introduction: Rocks and fossils do not come with dates on them. In fact, the very concept of strata representing long ages does not come from the rock strata themselves. That concept began with eighteenth-century French naturalist Georges Cuvier, picked up steam with Charles Lyell, and it has been in vogue ever since.
This is despite the fact that it causes more problems for interpreting rock strata than it solves. And today we know through lab experiments and natural disasters such as the eruption of Mt. Helens that major layering of rock strata can happen catastrophically in a short period of time.
