Astronomers discover Earth-sized exoplanet covered in volcanoes
Astronomers have discovered an Earth-sized planet that is highly volcanically active, which means it could possibly support life......»»
Astronomers discover alternative Earth likely covered with volcanoes
Imagine an Earth-sized planet that's not at all Earth-like. Half this world is locked in permanent daytime, the other half in permanent night, and it's carpeted with active volcanoes. Astronomers have discovered that planet......»»
Do volcanoes add more carbon than they take away?
In a new study published in the Journal of Geophysical Research: Biogeosciences, Zhong and colleagues discovered that a volcano in northeast China emits a small net amount of carbon each year. Over geological timescales, that could have a significant.....»»
Landslides Kill and Hurt Thousands, but Science Largely Ignores These Disasters
Compared with landslides, volcanoes and hurricanes get a lot more attention, as well as research funding.....»»
Radar satellite data reveals 19,000 previously unknown undersea volcanoes
A team of oceanographers at the Scripps Institution of Oceanography, working with a colleague from Chungnam National University and another from the University of Hawaii, has mapped 19,000 previously unknown undersea volcanoes in the world's oceans u.....»»
Predictive power of climate models may be masked by volcanoes
Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study published in Science Advances......»»
Was plate tectonics occurring when life first formed on Earth?
Earth is a dynamic and constantly changing planet. From the formation of mountains and oceans to the eruption of volcanoes, the surface of our planet is in a constant state of flux. At the heart of these changes lies the powerful force of plate tecto.....»»
Scientists share "comprehensive" map of volcanoes on Venus—all 85,000 of them
Intrigued by reports of recent volcanic eruptions on Venus? WashU planetary scientists Paul Byrne and Rebecca Hahn want you to use their new map of 85,000 volcanoes on Venus to help locate the next active lava flow. Their study was posted online ahea.....»»
A new study on Australian volcanoes has changed what we know about explosive "hotspot" volcanism
Our new study published in Nature Geoscience on an ancient chain of Australian volcanoes is helping to change our understanding of "hotspot" volcanism......»»
Giant volcanic "chain" spills secrets on inner workings of volcanoes
Volcanic relics scattered throughout the Australian landscape are a map of the northward movement of the continent over a "hotspot" inside the Earth, during the last 35 million years......»»
Venus: Proof of active volcanoes—at last
Venus is almost the same size, mass and density as Earth. So it should be generating heat in its interior (by the decay of radioactive elements) at much the same rate as the Earth does. On Earth, one of the main ways in which this heat leaks out is v.....»»
We finally have proof of active volcanoes on Venus
Researchers pored over images from Magellan's visit to Venus in the early 1990s. Enlarge / A perspective view across Maat Mons on Venus, based on Magellan radar data. (credit: NASA/JPL) Venus is almost the same size, ma.....»»
Quake swarms at neighboring Alaska volcanoes raise concerns
Not one but two volcanoes on the same island in Alaska's Aleutian chain were rocked by earthquakes on Friday, prompting concerns about a possible eruption......»»
Life in the smoke of underwater volcanoes
Deep down in the ocean at tectonic plate boundaries, hot fluids rise from hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as iron, manganese or copper. Some may also transport sulfides, methane and hydroge.....»»
Examining asphalt volcanoes" natural communities
Santa Barbara Channel's natural oil seeps are a beach-goer's bane, flecking the shores with blobs of tar. But the leaking petroleum also creates fascinating geologic and biologic features. About 10 miles off the coast of Santa Barbara, several jet-bl.....»»
Ice cores show even dormant volcanoes leak abundant sulfur into the atmosphere
Volcanoes draw plenty of attention when they erupt. But new research led by the University of Washington shows that volcanoes leak a surprisingly high amount of their atmosphere- and climate-changing gases in their quiet phases. A Greenland ice core.....»»
The Tonga Eruption Is Still Revealing New Volcanic Dangers
One year later, researchers are still marveling at the power of the Hunga Tonga explosion—and wondering how to monitor hundreds of other undersea volcanoes......»»
A year on, we now know why the Tongan eruption was so violent. It"s a wake-up call to watch other submarine volcanoes
The Kingdom of Tonga exploded into global news on January 15 last year with one of the most spectacular and violent volcanic eruptions ever seen......»»
Surprise magma chamber growing under Mediterranean volcano
Using a novel imaging technique for volcanoes that produces high-resolution pictures of seismic wave properties, a new study reveals a large, previously undetected body of mobile magma underneath Kolumbo, an active submarine volcano near Santorini, G.....»»
What are mud volcanoes?
Mud volcanoes form when a combination of mud, fluids, and gases erupt at the Earth’s surface. Enlarge / Engineers have tried to corral a mud volcano in Indonesia that has covered more than 1,700 acres with mud (credit: Eka Dhar.....»»
