Researchers confirm discovery of Earth's inner, innermost core 
Geologists at the University of Illinois have confirmed the discovery of Earth’s inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core.

Video: Lava makes its way to ocean in Hawaii
A Kilauea volcano lava flow that coursed its way through an all-but-abandoned Big Island subdivision reached the ocean early Thursday morning, according to the U.S. Geological Survey's Hawaiian Volcano Observatory.

Grand Canyon Still Grand but Older
By dating mineral deposits inside caves along the canyon’s walls, geologists now claim the canyon’s formation began 11 million years earlier than previous estimates.

Key component of Earth's crust formed from moving molten rock
Earth scientists are in the business of backing into history -- extrapolating what happened millions of years ago based on what they can observe now. Using this method, a team of Cornell researchers has created a mathematical computer model of the formation of granulite, a fine-grained metamorphic rock, in the Earth's crust.

Journey to the center of the Earth -- Imperial scientists explain tectonic plate motions
The first direct evidence of how and when tectonic plates move into the deepest reaches of the Earth is published in Nature today. Scientists hope their description of how plates collide with one sliding below the other into the rocky mantle could potentially improve their ability to assess earthquake risks.

A fresh look inside Mount St. Helens
Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don’t know.

Computer simulations strongly support new theory of Earth's core
Swedish researchers present in today’s Web edition of the journal Science evidence that their theory about the core of the earth is correct. Among other applications, the findings may be of significance for our understanding of the cooling down of the earth, and of the stability of the earth’s magnetic field.

Earth's getting 'soft' in the middle
Since we can’t sample the deepest regions of the Earth, scientists watch the velocity of seismic waves as they travel through the planet to determine the composition and density of that material. Now a new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly

Large earthquakes may broadcast warnings, but is anyone tuning in to listen?
There may be a way to detect the footfalls of large earthquakes a week or more before they strike. A Stanford professor thinks a method to provide such warnings may have been buried in the scientific literature for over 40 years.
