Fiery Volcano Offers Geologic Glimpse Into Land That Time Forgot -- with Video

The first scientists to witness molten lava from a deep sea volcano now report that the eruption was near a tear in the Earth’s crust that is mimicking the birth of a subduction zone. Earth’s current subduction zones are continually evolving but most formed 5 million to 200 million years ago.

Siberian Hot Springs Reveal Ancient Ecology

Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth’s early atmosphere, according to a theory that UChicago researcher Albert Colman of a volcanic crater in Siberia.

Electric Yellowstone

University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the plume of partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is bigger than it appears in earlier images made with earthquake waves.

Hot Stuff: Magma at Shallow Depth Under Hawaii

Researchers have found a new way to gauge the depth of the magma chamber that forms the Hawaiian Island volcanic chain, and determined that the magma lies much closer to the surface than previously thought.

Flow in Earth's Mantle Moves Mountains

Study in Nature suggests that some mountains in "mobile belts" -- regions of crustal fragments, such as in the Mediterranean, the Rockies, and the Himalayas -- can rise due to upward pressure from the semi-liquid mantle. The study proposes a model for predicting uplift and likely volcanic hotspots in such regions.

Scientists Find Ancient Asphalt Domes Off California Coast

They paved paradise and, it turns out, actually did put up a parking lot. A big one. Some 700 feet deep in the waters off California’s jewel of a coastal resort, Santa Barbara, sits a group of football-field-sized asphalt domes unlike any other underwater features known to exist. The deposits were discovered recently by scientists from the Woods Hole Oceanographic Institution (WHOI) and UC Santa Barbara (UCSB).
