Seafloor Hot Springs Significant Source of Iron in Earth's Oceans
"This proves that hydrothermal activity at the mid-ocean ridges impacts global ocean chemistry of important trace metals," said lead author Joseph Resing, a senior research scientist at the University of Washington's Joint Institute for the Study of the Atmosphere and Ocean, a partnership with the National Oceanic and Atmospheric Administration. "On longer timescales, it also impacts the productivity of the oceans."

Mini sponge fossil sheds new light on timing of early evolution
The sponge lends credence to the argument that early animal adaptations didn't happen all of sudden, but began earlier and happened more gradually. Proponents of this explanation contend that the Cambrian explosion was not the result of rapid speciation, but the simply the result of environmental and biological factors which made fossils likely to be preserved.

Paper suggests impacts blasted off parts of Earth’s starting material
It’s generally thought that the Earth was built out of asteroids called ordinary chondrites. Chondrites contain some of the most ancient minerals in the Solar System, and their composition suggests that they made up the majority of the material that collapsed to form our planet. But recent observations have shown that the composition of the Earth’s mantle doesn’t match that of ordinary chondrites, suggesting that something else is going on.

Balancing rocks trace history of 'jumping' earthquakes
US scientists say they have solved the riddle of why a collection of balancing rocks near the San Andreas fault has never been toppled by earthquakes. Their decade-long study concludes that quakes can stop or "jump" due to interactions between the San Andreas and the neighbouring San Jacinto fault. Models show that these interactions sent the biggest vibrations around the rock stacks, leaving them intact.

This Digital Map of the Seafloor Can Help Scientists Predict Environmental Change
We know less about the deep ocean than we do about the surface of Mars. But if we want to really understand how humans are impacting the Earth, we need to start looking down deep into the muck. That’s why scientists created the first digital map of the seafloor’s geologic composition.

24th August 79 - Vesuvius erupts
At noon on August 24, 79 A.D. the peak of Mount Vesuvius exploded, propelling a 10-mile mushroom cloud of ash and pumice into the stratosphere. For the next 12 hours, volcanic ash and a hail of pumice stones up to 3 inches in diameter showered Pompeii, forcing the city’s occupants to flee in terror. Some 2,000 people stayed in Pompeii, holed up in cellars or stone structures, hoping to wait out the eruption.

27th August 1883 - Krakatau explodes
The most powerful volcanic eruption in recorded history occurs on Krakatau (also called Krakatoa), a small, uninhabited volcanic island located west of Sumatra in Indonesia. Heard 3,000 miles away, the explosions threw five cubic miles of earth 50 miles into the air, created 120-foot tsunamis and killed 36,000 people.

The Supervolcano Under Yellowstone is Alive and Kicking
The wind shifts. The stench of rotten eggs makes it nearly impossible to breathe and the hot fog clouds my view. I hold my breath and close my eyes, imagining the fog growing thicker, crushing me. Then without warning the wind clears and I’m enveloped once again in the cold, dry air. The heat feels like a lost dream. I shiver as I analyze my surroundings.
