Archaeological excavations at the Aranbaltza site in the Basque Country coast (Northern Spain) have revealed several episodes of neandertal occupations with preserved wooden remains... In 2015, the excavation revealed two very well preserved wooden tools, one of which is a 15 cm-long digging stick... The detailed analysis of this tool and the luminescence dating of the sediment that bears the wooden remains indicate that the objects were deposited around 90,000 years ago, and thus were made by neandertals. The Micro-CT analysis and a close examination of the surface have shown that a yew trunk was cut longitudinally into two halves....

An Italian couple and their 11-year-old son died in a freak accident on Tuesday when they fell into a 10ft-deep hole that suddenly opened up in a highly active volcanic area near Naples. Police said the child strayed beyond safety barriers and was swallowed up by the pit, plunging into boiling hot mud at the Solfatara Crater in Pozzuoli, part of a huge volcanic area known as the Campi Flegrei or Phlegrean Fields. His father, 45, reportedly rushed to his rescue but also fell into the sink-hole. The boy’s mother, 42, then went to their aid, but she too was...

Before a volcano erupts, there are usually signs of what’s to come; small earthquakes, heat emission, and ground swelling, to name a few, have all been observed to precede eruptions. Volcanologists also monitor the changing composition of gas emissions at volcanoes in the months leading up to an eruption. However, precursory variations in gas have not yet been verified to occur in volcanoes hosting active lava lakes. To find out if volcanic gas emissions might also be used to predict eruptions at lava lake–hosting, carbon-poor volcanoes, Aiuppa et al. looked at Chile’s Villarrica volcano. Villarrica towers 2847 meters over the...

When Mount Vesuvius erupted and buried the Italian city of Pompeii in ash, killing 2,000 people, it was regarded as one of the most catastrophic natural disasters and is still studied heavily today. By comparison, a nearby supervolcano called Campi Flegrei, which means “burning fields,” would put the lives of 500,000 Italians at risk and cause damage that would extend to the surrounding nations.

A volcanic field off the shore of Sicily, near Naples, has become active, scientists report. The Campi Flegrei volcano is much larger than nearby Mt. Vesuvius, the volcano whose eruption destroyed the ancient city of Pompei. An eruption of this “supervolcano” could endanger much of Europe. News of the volcanic activity was made public less than a week after the blood of St. Januarius failed to liquefy when displayed in the Naples cathedral. Sicilians have long believed that when the miracle of St. Januarius does not occur, disaster will follow for the people of Naples. A supervolcano caused the largest...

The Italian name for the caldera — Campi Flegrei, or “burning fields”— is apt. The 7.5-mile-wide cauldron is the collapsed top of an ancient volcano, formed when the magma within finally blew. Though half of it is obscured beneath the crystal blue waters of the Mediterranean, the other half is studded with cinder cones and calderas from smaller eruptions. And the whole area seethes with hydrothermal activity: Sulfuric acid spews from active fumaroles; geysers spout water and steam and the ground froths with boiling mud; and earthquake swarms shudder through the region, 125 miles south of Rome. And things seem...

BEC CREW 22 DEC 2016 It's dangerously close to hitting a critical pressure point. A 12-km wide cauldron that forms a vast supervolcano on the coast of Italy is showing signs of reawakening after almost 500 years of inactivity. Not only is this site rumoured to be responsible for the extinction of the Neanderthals, it’s got 500,000 people living around it right now, and researchers say it appears to be approaching a critical pressure point that could lead to an eruption. You might imagine a supervolcano as like a regular volcano, only supersized, rising up out of the ground and...

A slumbering Campi Flegrei volcano under the Italian city of Naples shows signs of "reawakening" and may be nearing a critical pressure point, according to a study published Tuesday. Italian and French scientists have for the first time identified a threshold beyond which rising magma under the Earth's surface could trigger the release of fluids and gases at a 10-fold increased rate. This would cause the injection of high-temperature steam into surrounding rocks, said lead author Giovanni Chiodini, a researcher at Italy's National Institute of Geophysics and Volcanology in Bologna. "Hydrothermal rocks, if heated, can ultimately lose their mechanical resistance,...

A hidden "super volcano" near Pompeii threatens an eruption that could make Vesuvius look like a picnic, scientists warn. The Phlegraean Fields zone of intense seismic activity -- which the ancient Romans believed was the gateway to hell -- could doom millions of people in the Naples area if it erupts, Reuters reports. Scientists plan to drill more than two miles below its surface to monitor any signs of a pending eruption in the huge chamber of molten rock, but some experts fear that the drilling itself could trigger an earthquake or eruption. Areas like the Phlegraean fields "can give...

The ground on the western edges of Naples, Italy is rising, spurring worries of a possible volcanic eruption, but scientists now think they know exactly what is causing the uplift and may be able to better predict any potential eruption. Using GPS measurements, a group of scientists at the National Institute of Geophysics and Vulcanology in Italy monitored the ground’s motions for several years, and based on the patterns they observed, they believe the uplifting is caused by magma intruding from a shallow chamber. The rising motions of the ground reached a peak rate of about three feet per year...

'Catastrophic' event at Campi Flegrei 39,000 years ago Volcanic eruption near Naples may have killed Neanderthals Some researchers are suggesting that Neanderthals were driven to extinction by a massive volcanic eruption near Naples. The suggestion is one of the topics under debate this week at a conference at London's British Museum examining what forces led to the destruction of the Neanderthals and what led to the triumph of the homo sapiens. One new theory holds that a gigantic eruption of the volcano in the Campi Flegrei area near Naples 39,000 years ago was catastrophic for the Neanderthals. That was the...

The Neanderthals were a hardy species that lived through multiple ice ages and would have been familiar with volcanoes and other natural calamities. But the eruptions 40,000 years ago were unlike anything Neanderthals had faced before, Cleghorn and company say. For one thing, all the volcanoes apparently erupted around the same time. And one of those blasts, the Campanian Ignimbrite, is thought to have been the most powerful eruption in Europe in the last 200,000 years... The researchers acknowledge that there are gaps in the volcanoes theory. For instance, the time line needs to be better defined -- did...

Researchers have securely dated a prehistoric human stone tool industry that is thought to have been used by early modern humans, or possibly late Neanderthals, around the time when early modern humans were beginning to emerge in Europe, arguably sometime between 40,000 to 50,000 years B.P... The Uluzzian, a prehistoric stone tool techno-tradition represented by lithic artifacts unearthed by archaeologists at cave locations primarily in Italy and Greece, has been a central contender as a possible "transitional" industry between the typical stone tool types (the Mousterian) used by late European Neanderthals and those (Aurignacian, Châtelperronian) of the earliest modern human...

Neanderthals and other extinct human lineages might have been ancient mariners, venturing to the Mediterranean islands thousands of years earlier than previously thought. This prehistoric seafaring could shed light on the mental capabilities of these lost relatives of modern humans, researchers say. Scientists had thought the Mediterranean islands were first settled about 9,000 years ago by Neolithic or New Stone Age farmers and shepherds... For instance, obsidian from the Aegean island of Melos was uncovered at the mainland Greek coastal site of Franchthi cave in layers that were about 11,000 years old, while excavations on the southern coast of Cyprus...

IT LOOKS like Neanderthals may have beaten modern humans to the seas. Growing evidence suggests our extinct cousins criss-crossed the Mediterranean in boats from 100,000 years ago - though not everyone is convinced they weren't just good swimmers. Neanderthals lived around the Mediterranean from 300,000 years ago. Their distinctive "Mousterian" stone tools are found on the Greek mainland and, intriguingly, have also been found on the Greek islands of Lefkada, Kefalonia and Zakynthos. That could be explained in two ways: either the islands weren't islands at the time, or our distant cousins crossed the water somehow. Now, George Ferentinos of...

A scanty but varied ensemble of finds challenges the idea that Neandertal material culture was essentially static and did not include symbolic items. In this study we report on a fragmentary Miocene-Pliocene fossil marine shell, Aspa marginata, discovered in a Discoid Mousterian layer of the Fumane Cave, northern Italy, dated to at least 47.6-45.0 Cal ky BP. The shell was collected by Neandertals at a fossil exposure probably located more than 100 kms from the site. Microscopic analysis of the shell surface identifies clusters of striations on the inner lip. A dark red substance, trapped inside micropits produced by bioeroders,...

Dating of butchery marks crucial A multi-disciplinary team of French CNRS researchers, working with Norwegian and Russian scientists, studied the Byzovaya site in the Polar Urals in northern Russia. Using carbon 14 dating and an optical simulation technique, the team was able to put an accurate date on sediments and on mammoth and reindeer bones abandoned on the site. The bones bore traces of butchering by Mousterian hunters. The results intrigue scientists in more ways than one. They show that Mousterian culture may have lasted longer than scientists had originally thought. What's more, no Mousterian presence had ever been identified...
