A new study in Earth and Planetary Science Letters analyzed seismic waves that bombarded Earth's core and indicates that two or more continent-sized chunks of rock are colliding as they move at the…

Puh! Another big one. Earthquakes of magnitude 8.0 are big to put it mildly. Luckily it happened deeper in the crust than first anticipated and thus the resulting tsunami wasn't as devastating as it…

Ridges spidering through impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis in Geophysical Research Letters…

All men and women to the atlases! I do not know about you, but when there is some big event going on in the world, positive or negative, I run for maps. I want to know exactly where the action takes…

The Earth's core formed under more oxidizing condition's than previously believed, researchers have discovered through of series of laser-heated diamond anvil cell experiments at high pressure - 350,…

During an earthquake, waves emitted when the two sides of a fault move—or slip—rapidly past each other, create ground motion, with an average relative speed of about three feet per second. Not all…

In 1991, the Pinatubo volcano eruption was a disaster for the Philippines and the effects were noticed across the world - it threw tons of ash and other particles into the atmosphere, which caused…

A new study indicates that clay minerals, formed when water is present for long periods of time, cover a larger portion of Mars than previously thought. Clays were in some of the rocks studied by…

Giant crevasses that penetrate upward from the bottom of the   Larsen C Ice Shelf, the largest remaining ice shelf on the Antarctic Peninsula, make it more susceptible to collapse, according to…

The Grand Canyon is spectacular to look at but figuring out how old it is can be frustrating. A new paper says that conventional models and estimates of the last 150 years are way off - it is far…
