Becoming Habitable in the Habitable Zone
Scientists explore how interactions between a rocky planet's climate, mantle, and core can affect its evolution and determine whether it could sustain life.
The Role of Water in Earth's Tectonic Plumbing Systems
Tidal forces act on well water around the San Andreas Fault, giving researchers a new window into the hydrogeological structure of fault zones.
Frontiers in Geosystems: Solving the Puzzles
Putting some publishing action into deep Earth-surface interactions
Variable Mantle Lies Below Ancient Pieces of Earth's Crust
Underneath old and stable pieces of Earth's crust in North America, the mantle's uppermost portion contains multiple layers that change the velocities of seismic waves.
Which Geodynamo Models Will Work Best on Next-Gen Computers?
A new study uses identical tests to evaluate the accuracy and performance of current models of Earth's magnetic field, then extrapolates the results to anticipated "petascale" supercomputers.
Characterizing the Fault Beneath the Marmara Sea
Researchers mine seismic wave data to elucidate the stress relief system of the Main Marmara Fault beneath Turkey's inland sea.
Alaska's Semidi Segment Could Unleash a Devastating Tsunami
Study reveals structures along the Alaskan convergent margin capable of generating a powerful tsunami directed toward the United States's West Coast.
Deep-Sea Microbes Can Leave Records of the Past
Researchers use carbon signatures within sea sediments to identify microbial activity and also to date earthquakes.
P Wave Amplitude Decay Offers a Glimpse of Earth's Structure
Scientists look at deep earthquake signals to map how seismic waves lose energy in the upper mantle across the United States.
