Apr. 24, 2015 — Scientists have new data on Ethiopia's Rift Valley and Aluto volcano, a major volcano in the region. Aluto is Ethiopia's main source of geothermal energy, a low-carbon resource that is ... read more

Apr. 23, 2015 — Seismologists have discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known ... read more

Earthquake Potential Where There Is No Earthquake History

Apr. 22, 2015 — It may seem unlikely that a large earthquake would take place hundreds of kilometers away from a tectonic plate boundary, in areas with low levels of strain on the crust from tectonic motion. But ... read more

Apr. 21, 2015 — A seismology team finds that high volumes of wastewater injection combined with saltwater (brine) extraction from natural gas wells is the most likely cause of earthquakes near Azle, Texas, from late ... read more

Oldest Fossils Controversy Resolved

Apr. 20, 2015 — New analysis of world-famous 3.46-billion-year-old rocks is set to finally resolve a long running evolutionary controversy. The new research shows that structures once thought to be Earth's ... read more

Apr. 14, 2015 — Global climate has undergone periods of stability, but also instability, with abrupt, rapid and substantial climate changes occurring as a consequence of natural processes scientists still don't ... read more

Meteorites Key to the Story of Earth's Layers

Apr. 13, 2015 — A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers.The research by an international team of scientists confirmed the Earth's ... read more

Fragment of Continental Crust Found Under South East Iceland

Apr. 13, 2015 — Scientists have shown that south east Iceland is underlain by continental ... read more

Burying the Climate Change Problem

Apr. 13, 2015 — Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. Now, a team of researchers has reviewed ... read more

Apr. 9, 2015 — The onset of northern hemispheric glaciation cycles three million years ago has dramatically changed Arctic climate. Scientists have now for the first time reconstructed the history of Arctic climate ... read more

New Research Complicates Seismic Hazard for British Columbia, Alaska Region

Apr. 6, 2015 — The Pacific and North America plate boundary off the coast of British Columbia and southeastern Alaska is a complex system of faults capable of producing very large earthquakes. The recent 2012 Mw ... read more

Apr. 3, 2015 — A new study shows for the first time how carbon offered a mode of survival for some ocean life after one of the greatest mass extinctions in the history of ... read more

Apr. 3, 2015 — Seismologists have proven that the Hayward and Calaveras faults are essentially the same system, meaning that a rupture on one could trigger a rupture on the other, producing considerably larger ... read more

Apr. 1, 2015 — Researchers have analyze the microbial community in volcanically active soils. In a mofette close to the Czech river Plesná in north-western Bohemia, the team found numerous organisms that were ... read more

Mar. 31, 2015 — Geoscientists have revealed information about how continents were generated on Earth more than 2.5 billion years ago -- and how those processes have continued within the last 70 million years to ... read more

Mar. 30, 2015 — Researchers have identified a new source of methane for gas hydrates -- ice-like substances found in sediment that trap methane within the crystal structure of frozen water -- in the Arctic Ocean. ... read more

Mar. 30, 2015 — A new study has confirmed the existence of a positive feedback operating in climate change whereby warming itself may amplify a rise in greenhouse gases resulting in additional ... read more

Seabed Samples Rewrite Earthquake History Near Istanbul

Mar. 30, 2015 — Cores of marine sediment reveal an earthquake history of the Cinarcik Segment, a main branch of NAF, and suggest a seismic gap where the next earthquake is likely to rupture, as detailed in a new ... read more

Mar. 25, 2015 — A new finding challenges the established dogma that hydrogen exists in the form of a hydroxyl group (i.e., water) in silicate minerals that make up rocks, and is expected to open up new possibilities ... read more

Mar. 23, 2015 — By crushing minerals between diamonds, a new study suggests the existence of an unknown layer inside Earth: part of the lower mantle where the rock gets three times stiffer. The discovery may explain ... read more
