Builders of hydroelectric dams are required to perform seismic hazard studies before their designs are approved.
Using the most precise seafloor maps ever created of Antarctica's Ross Sea, Rice University researchers have discovered a long-dead river system that once flowed beneath Antarctica's ice and influenced how ice streams melted after Earth's last ice age. The research appears online this week in Nature Geoscience.
Rice University geophysicists use a new model to conclude that volcanic hot spots around the globe aren't moving as fast as recently thought.
A new study presents a method for identifying individual equatorial waves in wind and geopotential height fields using horizontal wave structures derived from classical equatorial wave theory.
A new study from Indiana University-Purdue University Indianapolis validates that the central core of the East Antarctic ice sheet should remain stable even if the West Antarctic ice sheet melts.
Flow of the Greenland Ice Sheet is likely to speed up in the future, despite a recent slowdown, because its outlet glaciers slide over wet sediment, not hard rock, new research based on seismic surveys has confirmed. This sediment will become weaker and more slippery as global temperatures rise and meltwater supply becomes more variable. The findings challenge the view that the recent slowdowns in ice flow would continue in the long term.
Stanford researchers show that lake sediments preserved within ancient supervolcanoes can host large lithium-rich clay deposits. A domestic source of lithium would help meet the rising demand for this valuable metal, which is critical for modern technology.
Tropical trees maintain high carbon accumulation rates into old age, according to a study published Aug. 16, 2017, in the open-access journal PLOS ONE by Michael Köhl from the Universität Hamburg, Germany, and colleagues.
Using high-speed photography and digital image correlation techniques, engineers show that friction along a faultline has a complex evolution during an earthquake that is dictated, in part, by slip velocity: the sliding of the two sides of the fault against one another.
There is a rising risk of human and domestic animal exposure to deadly Hendra virus (HeV) carried by fruit bats in Eastern Australia due to human intrusion into their habitats, human proximity to woodlands and vegetation loss, a new study reveals.
