Jan. 31, 2019 — New evidence from the cliffsides of Australia suggests that Earth's largest extinction event -- a volcanic cataclysm occurring roughly 252 million years ago -- extinguished plant life long ... read more

Jan. 31, 2019 — The heavy bombardment of terrestrial planets by asteroids from space has contributed to the formation of the early evolved crust on Earth that later gave rise to continents - home to human ... read more

Seas May Be Rising Faster Than Thought

Jan. 30, 2019 — A new study questions the reliability of how sea-level rise in low-lying coastal areas such as southern Louisiana is measured and suggests that the current method underestimates the severity of the ... read more

Jan. 29, 2019 — Earth is the only known planet with continents, and scientists are offering up new evidence that Earth's continental crust formed deep below mountainous continental arcs like the ... read more

Jan. 29, 2019 — A big earthquake occurred south of Istanbul in the summer of 2016, but it was so slow that nobody noticed. The earthquake, which took place at mid-crustal depth, lasted more than fifty days. Only a ... read more

Jan. 25, 2019 — Carbon capture and storage is a reliable way to store carbon dioxide emissions underground, with minimal chance of gas escaping through geological fault ... read more

Jan. 23, 2019 — Geologists demonstrate the reconstruction of the subduction of the Nazca Ocean plate, the remnants of which are currently found down to 1,500 kilometers, or about 900 miles, below the Earth's ... read more

'Silent Slip' Along Fault Line Serves as Prelude to Big Earthquakes, Research Suggests

Jan. 22, 2019 — Big earthquakes appear to follow a brief episode of 'shallow mantle creep' and 'seismic swarms,' suggests new research that offers an explanation for the foreshocks observed prior ... read more

Jan. 17, 2019 — A team of scientists has determined the number of asteroid impacts on the Moon and Earth increased by two to three times starting around 290 million years ago. Previous theories held that there were ... read more

Jan. 16, 2019 — The onset of the most recent ice age about 2.6 million years ago changed where the western Gulf of Mexico gets its supply of sediments. The finding adds new insight into how extreme climate change ... read more

Jan. 16, 2019 — Nepal was struck by an earthquake with a magnitude of 7.8 in 2015, but the country may still face the threat of much stronger temblor. This is the conclusion reached by researchers based on a new ... read more

Jan. 14, 2019 — Variations in the axial tilt of the Earth have significant implications for the rise and fall of the Antarctic Ice Sheet, the miles-deep blanket of ice that locks up huge volumes of water that, if ... read more

New Computer Modeling Approach Could Improve Understanding of Megathrust Earthquakes

Jan. 10, 2019 — Years before the devastating Tohoku earthquake struck the coast of Japan in 2011, the Earth's crust near the site of the quake was starting to stir. Researchers are using computer models to ... read more

Future of Planet-Cooling Tech: Study Creates Roadmap for Geoengineering Research

Jan. 8, 2019 — A new study sets out to establish a roadmap for responsible exploration of ... read more

Jan. 7, 2019 — Magma could rise from the upper mantle into the middle and upper crust beneath the Laacher See Volcano (Germany). The scientists present evidence of deep and low-frequency earthquakes caused by magma ... read more

A 'Pacemaker' for North African Climate

Jan. 2, 2019 — Researchers have analyzed dust deposited off the coast of west Africa over the last 240,000 years, and found that the Sahara, and North Africa in general, has swung between wet and dry climates every ... read more

Dec. 28, 2018 — As human activities cause the Earth's temperature to increase, reliable, well-studied weather patterns like the Madden-Julian Oscillation will change too, say ... read more

New Light Shed on What Drove Last, Long-Term Global Climate Shift

Dec. 19, 2018 — The quest to discover what drove the last, long-term global climate shift on Earth, which took place around a million years ago, has taken a new, revealing ... read more

Machine Learning-Detected Signal Predicts Time to Earthquake

Dec. 18, 2018 — Machine-learning research reveals the detection of seismic signals accurately predicting the Cascadia fault's slow slippage, a type of failure observed to precede large earthquakes in other ... read more

Earth's Cobalt Deposits Formed Much Later Than Previously Believed

Dec. 12, 2018 — Cobalt deposits in the Democratic Republic of Congo, one of Earth's largest cobalt-mining regions, are 150 million years younger than previously thought, according to a new study. The study ... read more
