Etna’s new lava-heavy eruption (pictured here on May 31), which is taking place pretty close to the summit craters.

Boris Behncke

Mount Etna is gifting the world with a new eruption, and as is par for the course for this decidedly strange mountain of fantastic fiery fountains, it’s putting on a breathtaking show. The photographs, taken by Boris Behncke, a volcanologist at the Etna Observatory (and someone who lives in the shadow of this Sicilian stratovolcano), speak for themselves. Footage obtained by several news networks, including ABC News, is proving to be equally resplendent stuff.

Here’s a quick rundown of what’s going on at Etna right now, and how it fits with the recent history of the volcano.

So, what’s happening?

As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.

The use of the word “belching” is probably more scientifically pertinent than you think. In somewhat crude terms, this sort of eruption involves a collection of gas escaping from the magma within the volcano’s conduit, a roughly vertical pipe that’s a bit like a volcano’s oesophagus. If it can’t quickly bubble out of the magma and sneak into the atmosphere, perhaps because the magma is a little more gloopy than it otherwise could be, this gas tends to gather together and form a large slug-like gassy mass. When this slug reaches the top of the conduit, it bursts forth from the volcano’s vent or fissure (one of several, in this case), sending blobs and flecks of lava skywards with it.

See? This eruption style is the volcanic equivalent of a burp, perhaps with a little bit of, um, extra stomach material being brought along for the ride. This is technically known as a Strombolian eruption style, named after Stromboli, another beautiful and reliably hyperactive Italian volcano found within the volcanic Aeolian Islands, which are all just north of Etna itself.

Sometimes this style can create fountains of lava tens of even hundreds of metres high; in this case, the volcanic burps appear to be a little minor but frequent, causing hyperactive spattering landing on the volcano’s slopes and onto a couple of lava flows.

As the blog post notes, as of the morning of May 31, a northern lava flow stretched out toward the Valle del Bove, a rather sizeable horseshoe-shaped pit on Etna’s eastern flanks. As it did so, the lava turned eastwards, and managed to stretch out at a distance of around 2,000 metres (nearly 6,600 feet). The second lava flow is more southerly; it’s sneaking along the inside of the Valle del Bove’s western wall. As of May 31, it’s about 3,000 metres (9,850 feet) long.

Interestingly, this southern flow is being fed from a crack right near the fissures that produced another substantial lava-rich eruption last December. Those fissures are pretty much brand-new: they emerged on Christmas Eve after 130 tremors at the volcano back then seemed to suggest magma was making its way to the surface.

Don’t worry; this eruption isn’t endangering anyone.

Although Etna has been active for some time, this eruption was significant as it was the first flank (side) eruption, not summit eruption, at Etna for more than a decade. According to the Smithsonian Institution’s Global Volcanism Program, this paroxysm was part of a prolonged volcanic sequence that began all the way back in September 2013.

Already bored with those December 2018 lava flows, this new river of lava is already partly burying them.

Where on Etna is this eruption taking place?

Although it varies from eruption to eruption, summit eruptions tend to be a little less dangerous to people who live on Etna’s considerably massive slopes than flank eruptions. If you have a prolific lava flow, one at the summit is less likely to make it far downslope, whereas a flank eruption stands a better chance. An explosion flank eruption, which could cause a cascade of lava outpourings, landslides and perhaps even pyroclastic flows, is a real risk, so anytime there’s signs of a flank eruption those at the INGV can, rather understandably, get a little anxious.

As Behncke points out in a recent tweet, this eruption is “sub-terminal.” This means that although it’s not taking place at the summit craters themselves, it’s pretty close to them, around 3,000 metres (9,850 feet) elevation. It’s only another 350 metres (1,150 feet) or so to the top.

Is this normal for Etna?

Definitely. Although a little unpredictable, Etna has been erupting in some form or another for years now. Back just this February, for example, ash clouds were seen rising skyward from a series of small blasts from the so-called Roof of the Mediterranean.

So there’s nothing to worry about then?

Right. All indications are, then, that this eruption poses no threat to any of the million or so people that call Etna’s flanks home. If you’re planning to visit Sicily in the near future, then worry not, you’re perfectly safe from Etna’s fireworks show.

Saying that, Etna certainly has and will again someday pose a threat: thanks to its strange and enigmatic magmatic plumbing system, this volcano can engage in a myriad of eruption styles, from quick-moving lava cascades to sudden, explosive magma-water blasts, some of which can be somewhat difficult to foresee.

On top of all that, it’s (very, very slowly) sliding into the Ionian Sea, which could one day lead to a major flank collapse. This could not only trigger a violent eruption but also a megatsunami that could find its way across to the eastern Mediterranean and devastate its shores. Don’t panic, though – there’s zero evidence that this, or any sort of major eruption, is “imminent” or “due” in any sense of the word.

It’s good to know then that researchers from all over the world, including the INGV, are keeping a very close eye on it. If something wicked is afoot with this tricksy volcano, don’t worry, they’ll be the first to let everyone know.

Etna’s brand-new lava-heavy eruption( envisioned here on Might31), which is happening quite near the top craters

Here’s a fast rundown of what’s going on at Etna today, and how it fits with the current history of the volcano.

As Italy’s National Institute of Geophysics and Volcanology (INGV) discusses on a current article, the nascent eruption started on the night of Might29 Beginning by producing a thick column of ash increasing from the New Southeast Crater, it paved the way on Might 30 to an even more lava-heavy display screen in the location, including 2 cracks blenching out lava.

Using the word” belching “is most likely more clinically significant than you believe. In rather unrefined terms, this sort of eruption includes a collection of gas getting away from the lava within the volcano’s avenue, an approximately vertical pipeline that’s a bit like a volcano’s oesophagus. If it can’t rapidly bubble out of the lava and slip into the environment, maybe due to the fact that the lava is a little bit more gloopy than it otherwise might be, this gas tends to congregate and form a big slug-like gassy mass. When this slug arrives of the avenue, it ruptures forth from the volcano’s vent or crack (among a number of, in this case), sending out blobs and flecks of lava skywards with it.

See? This eruption design is the volcanic equivalent of a burp, maybe with a bit of, um, additional stomach product being brought along for the flight. This is technically referred to as a Strombolian eruption design, called after Stromboli, another stunning and dependably hyper Italian volcano discovered within the volcanic Aeolian Islands, which are all simply north of Etna itself.

Often this design can produce water fountains of lava 10s of even numerous metres high; in this case, the volcanic burps seem a little small however regular, triggering hyper spattering landing on the volcano’s slopes and onto a number of lava circulations.

As the article notes, since the early morning of May 31, a northern lava circulation extended towards the Valle del Bove, a rather significant horseshoe-shaped pit on Etna’s eastern flanks. As it did so, the lava turned eastwards, and handled to extend at a range of around 2,000 metres (almost 6,600 feet). The 2nd lava circulation is more southerly; it’s slipping along the within the Valle del Bove’s western wall. Since Might 31, it has to do with 3,000 metres (9,850 feet) long.

Remarkably, this southern circulation is being fed from a fracture right near the cracks that produced another significant lava-rich eruption last December. Those cracks are basically new: they emerged on Christmas Eve after 130 tremblings at the volcano at that time appeared to recommend lava was making its method to the surface area.

Do not stress; this eruption isn’t threatening anybody.

Where on Etna is this eruption happening?

Although it differs from eruption to eruption, top eruptions tend to be a little less harmful to individuals who survive on Etna’s substantially enormous slopes than flank eruptions. If you have a respected lava circulation, one at the top is less most likely to make it far downslope, whereas a flank eruption stands a much better possibility. A surge flank eruption, which might trigger a waterfall of lava profusions, landslides and maybe even pyroclastic circulations, is a genuine danger, so anytime there’s indications of a flank eruption those at the INGV can, rather not surprisingly, get a little distressed.

As Behncke mentions in a current tweet, this eruption is “sub-terminal.” This suggests that although it’s not happening at the top craters themselves, it’s quite near them, around 3,000 metres (9,850 feet) elevation. It’s just another 350 metres (1,150 feet) or two to the top.

Is this typical for Etna?

Absolutely. Although a little unforeseeable, Etna has actually been emerging in some type or another for many years now. Back simply this February, for instance, ash clouds were seen increasing skyward from a series of little blasts from the so-called Roofing system of the Mediterranean.

Right. All indicators are, then, that this eruption postures no hazard to any of the million or two individuals that call Etna’s flanks house If you’re preparing to check out Sicily in the future, then stress not, you’re completely safe from Etna’s fireworks reveal.

Stating that, Etna definitely has and will once again sooner or later position a danger: thanks to its weird and enigmatic magmatic pipes system, this volcano can take part in a myriad of eruption designs, from quick-moving lava waterfalls to unexpected, explosive magma-water blasts, a few of which can be rather hard to predict.

It’s excellent to understand then that scientists from all over the world, consisting of the INGV, are keeping a really close eye on it. If something wicked is afoot with this tricksy volcano, do not stress, they’ll be the very first to let everybody understand.
