YELLOWSTONE volcano could be about to erupt and challenge humanity’s existence as a spate of mini-quakes have been felt around the fearsome caldera. During the month of April, a total of 63 earthquakes struck around the Wyoming based supervolcano. All of the tremors were relatively small, with the largest registering at 2.6 on the Richter scale, hitting on April 29. But experts have warned that it is not necessarily about the strength of an earthquake around a volcano, but more the quantity of them. Some scientists believe that tremors around a volcano could be a sign that it might blow....

Eight >50K foot high volcanic eruptions in the last week and a half. I have only been watching him for a few weeks but this seems newsworthy. No one else seems to be covering it. 7

Scientists have discovered a stunning volcanic ‘lost world’ off the coast of Tasmania. Experts on the Commonwealth Scientific and Industrial Research Organisation (CSIRO), vessel ‘Investigator’ made the find while mapping the seafloor 249 miles east of Tasmania. The project is led by scientists from the Australian National University. CSIRO is Australia’s national science agency. A chain of ‘seamounts’, or undersea mountains, were spotted in deep water, offering the first glimpse of a spectacular “underwater world.” Scientists say that the mountains rise up to 9,843 feet from the seafloor, but the highest peaks are still 6,562 feet beneath the waves. “Our...

It's not only a possibility in the Hawaiian Islands. A chain of about 40 volcanos runs along the West Coast between Canada and Mexico and all have the potential to become active. (The potential for each peak is outlined in the gallery above.) They've all erupted at least once in the past 10,000 years and they all have a supply of magma under them.

Roger Bilham, a geophysicist at the University of Colorado, Boulder, informed that, in this year, the planet would face more powerful earthquakes and the magnitude level will be 7.0 or more. It can even reach 9.0. He stated that the number of earthquakes could reach up to 20 in 2018. The published report says, when the planet will enter in to slow rotation period, that will decrease the centrifugal force and tighten the planet’s equator. After that, the tectonic plates will crush with each other. The force that will erupt from this event will start super earthquakes on Earth. The...

Scientists analyzing a volcanic eruption at a mid-ocean ridge under the Pacific have come up with a somewhat contrarian explanation for what initiated it. Many scientists say undersea volcanism is triggered mainly by upwelling magma that reaches a critical pressure and forces its way up. The new study says the dominant force, at least in this case, was the seafloor itself -- basically that it ripped itself open, allowing the lava to spill out. The eruption took place on the East Pacific Rise, some 700 miles off Mexico. "Mid-ocean ridges are commonly viewed as seafloor volcanoes, operating like volcanoes on...

Magma located under areas that include the Yellowstone region and the western margin of North and South America can erupt violently, spewing vast quantities of ash into the air, followed by slower flows of glassy, viscous magma. [A] new study by University of Wyoming researchers suggests scientists can go back to the past to study present-day solidified magma chambers where the erosion has removed overlying rock, exposing granite underpinnings. One such large granite body, the 2.62 billion-year-old Wyoming batholith, extends more than 125 miles across central Wyoming. University of Wyoming earth scientist Davin Bagdonas traversed the Granite, Shirley and Laramie...

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...

It’s not very often that I comment on news articles, but a reader of the blog recently brought this one to my attention, and it hits close to home. The article is in the Washington Post’s Travel section and is entitled, “In Guatemala, a treacherous hike to one of the world’s most active volcanoes”. That title pretty much covers why I’m so upset – and conflicted – about the author of the piece is writing about. Anyone who knows me knows that I love volcanoes. BUT. I can’t stress enough that the Santiaguito hikes, conducted in this manner, ARE NOT...

Several massive volcanic erupted around the world in 2015. Indonesia’s Mount Sinabung, one of more than 100 active volcanoes in the country, emitted enormous plumes of smoke and ash throughout the year, leading to the evacuation of more than 10,000. And just earlier this month, Nicaragua’s Momotombo volcano reactivated after it was dormant for more than 100 years. Here are the the other volcanoes that lit up the sky this year.

Mass extinction events are sometimes portrayed in illustrations of volcanic eruptions causing widespread destruction. According to Dr. Richard E. Ernst of Carleton University, Ottawa, Canada, expert on Large Igneous Provinces (LIPs), this interpretation may have some truth behind it, but not in the instantaneous way we might think. Ernst will report on his research on 1 November at the Geological Society of America's Annual Meeting in Baltimore, Maryland, USA. The basaltic lava flowing from ancient volcanoes and the portion of magma (liquid rock) emplaced underground can create geologic conditions linked with climate change and, subsequently, extinction events. This climatic effect...

“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...

Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly regular cycles, ranging from two weeks to 100,000 years -- and, that they erupt almost exclusively during the first six months of each year. The pulses -- apparently tied to short- and long-term changes in earth's orbit, and to sea levels--may help trigger natural climate swings. Scientists have already speculated that volcanic cycles on land emitting large amounts of carbon...

Give climate change credit for one thing: it’s endlessly versatile. There was a time we called it global warming, which meant what it said: the globe would get warmer. It was only later that we appreciated that a planet running a fever is just like a person running a fever, which is to say it has a whole lot of other symptoms: in this case, droughts, floods, wildfires, habitat disruption, sea level rise, species loss, crop death and more. Now, you can add yet another problem to the climate change hit list: volcanoes. That’s the word from a new study...

Geoscientists now overwhelmingly agree that a single large asteroid or comet impact, such as Chicxulub in the Yucatan peninsula of Mexico, could not have been the sole cause of the end-Cretaceous mass extinction. Instead, new research in both planetary/space science and multiple earth-science specialties reveals that concomitant volcanic activity and the associated climate and environmental changes were significant contributing factors in four of the five major mass extinctions in Earth history.

Ajai RajSeptember 8, 2014 Last Friday's eruption at Iceland's Bardarbunga volcano had many worried about the possible impacts of a larger eruption on air travel. Another eruption at Hawaii's Kilauea volcano has caused a state of emergency to be declared on Big Island, as lava flows from the ongoing eruption have advanced within a mile of a residential zone. That's just one example of how much danger volcanoes pose to the U.S. — and we aren't doing much about it. Compared with Iceland, the U.S. is much more vulnerable to volcanic disasters — and has been failing at monitoring these...

Mount Fuji, or Fujisan as it is known in Japanese, is the highest point on the archipelago (rising to 3,776 metres) and the national emblem, immortalised in countless etchings. In June last year Unesco added it to the World Heritage list as a "sacred place and source of artistic inspiration". But it is still an active volcano, standing at the junction between the Pacific, Eurasian and Philippine tectonic plates. Though it has rarely stirred in recorded history, it is still potentially explosive. The Tohoku – or Great East Japan – earthquake on 11 March 2011 triggered a devastating tsunami, which...

Tamu Massif: The Most Massive Volcano Most of the world's largest features are so clearly visible that they have been known and recognized for hundreds of years. One exception is Tamu Massif. It is now recognized to be a single volcano - instead of a volcano complex with multiple vents. Tamu Massif has a footprint that covers more area than any other volcano - about 120,000 square miles (310,800 square kilometers) - an area about the size of New Mexico. It also has a larger mass than any other known single volcano on Earth. How could this enormous volcano have...

Nature of mysterious hot spot revealed by “photogeology” Analysis of new images of a curious “hot spot” on the far side of the Moon reveal it to be a small volcanic province created by the upwelling of silicic magma. The unusual location of the province and the surprising composition of the lava that formed it offer tantalizing clues to the Moon’s thermal history. The hot spot is a concentration of a radioactive element thorium sitting between the very large and ancient impact craters Compton and Belkovich that was first detected by Lunar Prospector’s gamma-ray spectrometer in 1998. The Compton-Belkovich Thorium...

Some worrying developments are taking place at the Super Volcano located beneath Yellowstone National Park; the kind of developments that were seen shortly before other volcanoes erupted. Not only was there a sudden rise in the elevation of the ground, and development of new cracks, but a gas called Helium-4, a very rare type of Helium, has begun coming out of the surface. It is the presence of this gas that has scientists quite concerned. If the Yellowstone Super Volcano were to erupt, it would be 2,000 times bigger than the eruption of Mount St. Helens in the 1980′s. Everything...
