May 22, 2015 — A research team has developed a tool that allows a 3D journey in ten sites of geological and palaeontological interest in the Guadalquivir basin (Huelva, Spain). In the virtual tour, developed with ... read more

May 6, 2015 — When tectonic plates collide, they produce earthquakes like the recent one in Nepal. Researchers are providing new ways to explain how and why earthquake supercycles occur in zones where one plate ... read more

May 4, 2015 — Scientists have addressed the 'uncomfortably close' occurrence of the Chicxulub impact in the Yucatan and the most voluminous phase of the Deccan Traps flood basalt eruptions in India. ... read more

May 4, 2015 — In the history of continental drift, India has been a mysterious record-holder. More than 140 million years ago, India was part of an immense supercontinent called Gondwana, which covered much of the ... read more

May 4, 2015 — Axial Seamount, an active underwater volcano located about 300 miles off the coast of Oregon and Washington, appears to be erupting -- after two scientists had forecast that such an event would take ... read more

Apr. 30, 2015 — The theory that an asteroid impact killed off the dinosaurs 66 million years ago is well accepted, but one puzzle is why another global catastrophe -- the huge, million-year eruption of the Deccan ... read more

Apr. 29, 2015 — A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving ... read more

Apr. 28, 2015 — River deltas, low-lying landforms that host critical and diverse ecosystems as well as high concentrations of human population, face an uncertain future. Even as some deltas experience decreased ... read more

Apr. 28, 2015 — Geoscientists have helped prove that some of the ocean's underwater volcanoes did not erupt from hot spots in the Earth's mantle but instead formed from cracks or fractures in the oceanic ... read more

Apr. 27, 2015 — Teasing out how slow, silent earthquakes respond to tidal forces lets researchers calculate the friction inside the fault, which could help understand when and how the more hazardous earthquakes ... read more

Apr. 27, 2015 — Hot vents on the seabed could have spontaneously produced the organic molecules necessary for life, according to new research. The study shows how the surfaces of mineral particles inside ... read more

Apr. 24, 2015 — The world's smallest spectrometer has successfully measured tiny deformations of the Earth's crust, of the order of one millimeter, over a length of one thousand kilometers. Researchers ... read more

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. 24, 2015 — This map provides a picture of the nation's geologic basement. More than 80 pieces of crust have been added to the nation's basement since the Earth began preserving crust about 3.6 billion ... read more

Ascent or No Ascent? How Hot Material Is Stopped in Earth's Mantle

Apr. 24, 2015 — Gigantic volumes of hot material rising from the deep earth's mantle to the base of the lithosphere have shaped the face of our planet. Provided they have a sufficient volume, they can lead to ... 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
