    Centuries ago, a native Central American people terrified of a witch believed to live deep in the earth used to sacrifice children and young women to Nicaragua's Masaya volcano. Today, the crater southwest of the capital Managua is an international tourist magnet, where photo-snapping visitors scramble among sulfurous fumes to get views of its bubbling lava—a rare sight. The only volcanoes in the world to boast lakes of incandescent magma are Masaya, Hawaii's Kilauea and Nyiragongo in the Democratic Republic of Congo, explained a Nicaraguan geographer and environmentalist, Jaime Incer.

    Science Daily ^ | 5/11/2016 | University of Sydney
    The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney and the California Institute of Technology (Caltech). Led by a PhD candidate at the University of Sydney's School of Geosciences, researchers used the Southern Hemisphere's most highly integrated supercomputer to reveal flow patterns deep in the Earth's mantle -- just above the core -- over the past 100 million years. The flow patterns explain how the enigmatic bend in the Hawaiian-Emperor seamount chain arose. True to the old adage -- as above, so below -- the...

    Tubular microtunnels believed to be the trace fossils formed by microbes inhabiting volcanic rock interiors have only been reported in oceanic and subglacial settings. This is the first observation of such features in basaltic volcanic glass erupted in a continental lake environment, the Fort Rock volcanic field. As a result, the record of subsurface microbial activity in the form of endolithic microborings is prospectively expanded. Our understanding of the range of environments and conditions that microtunnels can form in is enhanced along with our knowledge of potentially habitable environments on Earth and beyond. The Fort Rock volcanic field has analogous...

    Although fears of a Yellowstone volcanic blast go viral every few years, there are better things to worry about than a catastrophic supereruption exploding from the bowels of Yellowstone National Park. Scientists at the U.S. Geological Survey's (USGS) Yellowstone Volcano Observatory always pooh-pooh these worrisome memes, but that doesn't mean researchers are ignoring the possible consequences of a supereruption. Along with forecasting the damage, scientists constantly monitor the region for signs of molten rock tunneling underground. Scientists scrutinize past supereruptions, as well as smaller volcanic blasts, to predict what would happen if the Yellowstone Volcano did blow. Here's a deeper...

    On 14 April, a magnitude-6.2 earthquake struck the Japanese island of Kyushu. Two days later, Japanese officials reported towering plumes of smoke at Mount Aso, a volcano 42 kilometers away from the quake’s epicenter. A small eruption was occurring. Could the distant earthquake have triggered it? Mount Aso has had far bigger eruptions over the past few years, well before the earthquake occurred, so it was probably just a coincidence. But a new study concludes that the idea of so-called far-field triggering is not so far-fetched. Big earthquakes can slosh around the bubbly magma underneath volcanoes hundreds of kilometers away,...

    More than 25 million people live in the vicinity of Mt. Popocatepetl, including Mexico City’s 18 million residents. At 2:32 local time on Tuesday morning, the most dangerous volcano in Mexico roared to life in spectacular fashion, and this has many experts extremely concerned about what is coming next. Popocatepetl is an Aztec word that means “smoking mountain”, and historians tell us that once upon a time entire Aztec cities were buried in super-heated mud from this volcano. In fact, the super-heated mud flows were so deep that they buried entire Aztec pyramids. A full-blown eruption of Mt. Popocatepetl would...

    Up to 12 massive volcanic blasts occurred between 8 million and 12 million years ago in Idaho's Snake River Plain, leading up to today's Yellowstone supervolcano, new research reveals. A dozen of these ancient supereruptions took place along the Yellowstone hotspot track, researchers reported Feb. 10 in the journal Geological Society of America Bulletin. The trail of eruptions marks where the North American tectonic plate sailed over a superhot blob of mantle rock called a hotspot. (The mantle is the rocky layer between Earth's crust and core.) Though learning of more supereruptions in the West may seem unsettling, the findings...

    Science Daily ^ | 1/18/2016 | University of Southampton
    Around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this 'Snowball Earth', according to new research led by the University of Southampton. Many aspects of this extreme glaciation remain uncertain, but it is widely thought that the breakup of the supercontinent Rodinia resulted in increased river discharge into the ocean. This changed ocean chemistry and reduced atmospheric CO2 levels, which increased global ice coverage and propelled Earth into severe icehouse conditions. Because the land surface was then largely covered...

    Volcanic eruptions have occurred at their highest rate in 300 years, and experts caution that there could be a massive "super-volcano" with the potential to kill millions and destroy substantial amounts of wildlife. Scientists at the European Science Foundation said super-volcanoes could erupt within the next 80 years, reported the Tech Times. Researchers said the active volcanoes that could prove to be the most dangerous are Yellowstone in Wyoming, Mount Vesuvius in Campagnia, Italy, and Popocatépetl near Mexico City. If any of the three erupt, the damage would be "beyond the imagination of anything man’s activity and global warming could...

From what I've read this is a virtually certainty in the next 2000 years. Apparently an eruption 60+ years ago "loosened" a massive piece of rock from the side of the mountain creating a 6 foot "crack" as it moved towards the Atlantic ocean. If and when this 20+ mile piece of rock collapses into the ocean, a maga-tsunami would be generated that could be up to to 1000 feet high, moving across the...

Prior work by investigators has traced the cause to plague-carrying fleas borne by rats that jumped ship in trading ports. In addition, historical researchers believe that famine in northern Europe before the plague came ashore may have weakened the population there and set the stage for its devastation. Now, new research using a unique combination of ice-core data and written historical records indicates that the cool, wet weather blamed for the...

    Two hundred years ago, the greatest eruption in Earth’s recorded history took place. Mount Tambora—located on Sumbawa Island in the East Indies—blew itself up with apocalyptic force in April 1815.
 After perhaps 1,000 years’ dormancy, the devastating evacuation and collapse required only a few days. It was the concentrated energy of this event that was to have the greatest human impact. By shooting its contents into the stratosphere with biblical force, Tambora ensured its volcanic gases reached sufficient height to disable the seasonal rhythms of the global climate system, throwing human communities worldwide into chaos. The sun-dimming stratospheric aerosols produced...

    Repeatedly throughout Earth's history, giant pools of magma greater than 100 cubic miles in volume have formed a few miles below the surface. They are the sources of super-eruptions -- gigantic volcanic outbursts that throw 100 times more superheated gas, ash and rock into the atmosphere than run-of-the-mill eruptions, enough to blanket continents and plunge the globe into decades-long volcanic winters. Now a team of geologists have developed a new "geospeedometer" that they argue can help resolve this controversy by providing direct measurements of how long the most explosive types of magma existed as melt-rich bodies of crystal-poor magma before...

        Oldest human footprints found on volcano   19:00 12 March 03   NewScientist.com news service   The trails of footprints (A and B) have as many as 27 steps (Image: Paolo Mietto and Marco Avanzini)   Three primitive humans who scrambled down a volcano's slopes more than 325,000 years ago left their footprints fossilised in volcanic ash. If the ages of the trails are confirmed, they could be the earliest known footprints of our Homo ancestors. Paolo Mietto of Padua University and his colleagues examined three tracks of footprints on the Roccamonfina volcano in southern Italy, known to locals as...

    The newly-discovered footprints descending an inclined slope of an extinct volcano (Pic: University of Padua)  Markings in hardened volcanic ash, dubbed "devils' trails" by local Italian villagers, have been confirmed as the oldest-known footprints ever made by humans. The fossilised hand and footprints belong to three early humans who were probably climbing down the side of the Roccamonfina volcano in southern Italy about 385,000 to 325,000 years ago, report a team of Italian palaeontologists in today's issue of the journal, Nature. "We believe that these tracks are the oldest human footprints found so far," said Professor Paolo Mietto of...

    It's official: the oldest human footprints ever found are 345,000 years old, give or take 6000. Known as the "devils' trails", they have been preserved in volcanic ash atop the Roccamonfina volcano in Italy. The prints were first described to the world by Paolo Mietto and colleagues of the University of Padova in Italy in 2003 after amateur archaeologists pointed them out. At the time, the team estimated that the prints were anywhere between 385,000 and 325,000 years old, based on when the volcano was thought to have last erupted. Now, Stéphane Scaillet and colleagues at the Laboratory of Climatic...

    Blue Flames and a Blue Acid Lake Indonesia's Kawah Ijen Volcano, on the island of Java, has two of the most unusual occurrences on Earth. The first is an active solfatara that emits hot, flammable sulfurous gases. These ignite as they enter Earth's oxygen-rich atmosphere and burn with an electric blue flame. Some of the gas condenses in the atmosphere to produce flows of molten sulfur that also burn with an electric blue flame. The flames are difficult to see during the day but illuminate the landscape at night. The second occurrence is a one-kilometer-wide caldera lake filled with turquoise...

    April 23, 2015 – University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber. The hot rock in the newly discovered, deeper magma reservoir would fill the 1,000-cubic-mile Grand Canyon 11.2 times, while the previously known magma chamber would fill the Grand Canyon 2.5 times, says postdoctoral researcher Jamie Farrell, a co-author of the study published online today in the journal Science. “For the first time, we have imaged the continuous volcanic plumbing system...

    TOKYO (Reuters) - Mount Aso, a volcano located on Japan's southernmost main island of Kyushu, erupted on Monday, Japan's Meteorological Agency said, sending up huge plumes of grey ash and smoke. Japan lies on the "Ring of Fire" - a horseshoe-shaped band of fault lines and volcanoes around the edges of the Pacific Ocean - and is home to more than 100 active volcanoes.

    Sergio Frau suspects Plato was writing about a tidal wave on Sardinia... Writer and journalist Sergio Frau is another. After researching the island for a decade, Frau suspects a mysterious disaster that devastated Sardinia 3,200 years ago was in fact a tidal wave, which boosts the theory that Sardinia and Atlantis are one and the same, reports the Guardian. Stefano Tinti, an expert on tidal waves who recently visited the island with Frau along with a dozen other experts, says 350 tidal waves have occurred in the Mediterranean over the last 2,500 years and one might explain why all of...

    In April 1815, the most powerful volcanic blast in recorded history shook the planet in a catastrophe so vast that 200 years later, investigators are still struggling to grasp its repercussions. It played a role, they now understand, in icy weather, agricultural collapse and global pandemics — and even gave rise to celebrated monsters. Around the lush isles of the Dutch East Indies — modern-day Indonesia — the eruption of Mount Tambora killed tens of thousands of people. They were burned alive or killed by flying rocks, or they died later of starvation because the heavy ash smothered crops.

    “Is the number of volcanic eruptions worldwide increasing? “Yes,” answers Michael Snyder in this startling article.“ During the 20th century, there were a total of 3,542 volcanic eruptions globally. That works out to approximately 35 eruptions per year. That may sound like a lot, but according to Volcano Discovery there are 36 volcanoes erupting around the world right now. In other words, the number of volcanoes erupting as you read this article is greater than the 20th century’s yearly average.“ And all of this is part of a larger trend. In 2013, we witnessed the most volcanic eruptions worldwide that...

    Ecuador's President Rafael Correa declared a state of emergency yesterday as the dangerous Cotopaxi volcano rumbled to life and prompted evacuation orders in several villages threatened by landslides. “As a precautionary measure, a total of 400 people have been evacuated,” the president said in his radio and television address just before signing the decrees. The volcano, which towers to 5,897 meters (19,350 feet) high, is considered one of the most threatening in the region — both because of its size and because it is so close to well-populated towns. “The situation developing at Cotopaxi is a serious threat that has...
