Campi Flegrei Supervolcano may have resumed a burning cycle of massive eruptions



This does not mean that an ancient volcano will erupt, but new data show that Campi Flegrei forms a magma.

Campi Flegrei – The massive caldera system on the western side of Naples in southern Italy may not be as dormant as we think. According to the study just published Science progress, The ancient supervolcano has a rhythm to its hell explosion – the music may just begin.

It does not mean that Campi Flegrei will rupture in the near future. Sleep giants point to the immediate threat to 1.5 million people in Naples. Science alarm.

However, during the long history of the supernatural, a violent massive explosion at Campi Flegrei seems to match a certain pattern. This may once again be unfolded. According to a recent study, volcanoes appear to be forming magma deep under the earth, pointing out "the start of a new caldera cycle at Campi Flegrei".

"We propose Campi Flegrei's subvolcanic piping system is now entering a new build-up phase, potentially leading to a massive explosion at some undetermined point in the future."

Volatile history

Campi Flegrei, also known as Phlegraean Fields, is one of the most active vegetation in the world. The imposing Caldera system is "the largest volcano in Naples, home to the famous Vesuvius," NASA explains.

The huge volcanic rock called "Fiery Fields" is made up of 24 craters and volcanic products (a symbolic conical structure of volcanoes and lava piled around the lower vents). Most of Campi Flegrei is hidden beneath the waters of Naples Bay, but much of the Caldera is on the ground. In other words, you can go right in.

Adventurers enjoying trekking the caldera can discover some of the many fumaroles marking openings (supervolcano) in Earth's crust where smoke is emitted. For example, the photo below captures fumarole from Campfigrei's Solfatara volcano (volcanic crater that emits sulfur).

The area offers enchanting wild beauty, but actually the most dangerous volcano on the planet, Campi Flegrei Discover magazine. The history of the problem is characterized by two intense "explosions" of the largest volcanic eruptions in Europe during the past 40,000 years.

The first known as the Campanian Ignimbrite eruption shook the Earth about 39,000 years ago, spreading the Earth over an estimated area of ​​about 1.4 million square miles. The mega-eruption drove the planet to "the winter of the volcano" and probably responsible for the major global extinction event that could destroy the Neanderthals.

Recent Past

The most recent volcanic eruption at Campi Flegrei occurred fairly lightly about 500 years ago. With this latest explosion, a new mountain called Monte Nuova has been formed with eight days of lava burning.

In the long history of the supervolcano there are about 20,000 similar "taming" eruptions dating back to 60,000 years ago. Volcanologists have discovered hidden secrets in the chemical composition of the crystallized magma after investigating the remaining material in all these events, including two Mega volcanic eruptions of the caldera.

When it was revealed, the chemistry of the volcanic rocks described a certain pattern, suggesting that the explosion followed a certain cycle. And since the material settled after the latest explosion has also appeared in some minor cases of supercontinuities, the team estimated that the cycle might have just begun again.

Like the eruption of Monte Nuova, this case also produces magma that is saturated with carbon dioxide-rich gas. What is remarkable about these special events is that it happened just before the Campanian Ignimbrite and Neapolitan Yellow Tuff eruptions.

"Our data show that the most recent eruption of Monte Nio is characterized by magma, which supplied the early stages of Caldera pre-emptive activity and caldera formation eruptions, and very differentiated magma.

"This explosion represents a state change in the magma storage state, and it is a good idea to start releasing a significant amount of volatiles from the shallow reservoir," the team said, "this will indicate that a massive magma body is now accumulating." did. Under Campi Flegrei. "

Does this mean that the supervolcano is cooking a new gigantic eruption? Francesca Forni, a volcanologist at Nanyang Technological University in Singapore, says research director Francesca Forni.

"We are not really sure what the next step will be," Forni said. Geographic countryExplaining that magma can ignite or cool new sedimentation cycles and resume drowsiness.

As she pointed out, the chemical analysis of the last eruption was "[s] magmatic reservoirs may be "ready" to accommodate magmas from recharging without frequent spitting.
