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...

Archaeologists have discovered fragments of one of the world's oldest sculptures, a lion-faced figurine estimated at 32,000 years old, from the dirt floor of a cave in southern Germany. The ivory figure, along with a tiny figurine known as the Venus of Hohle Fels, marks the foundation of human artistry. Both were created by a Stone Age European culture that historians call Aurignacian. The Aurignacians appear to have been the first modern humans, with handicrafts, social customs and beliefs. They hunted reindeer, woolly rhinoceros, mammoths and other animals. The Lion-Man sculpture, gradually re-assembled in workshops over decades after the fragments...
