Mar. 24, 2017 — The striking North Face of the Bernese Alps is the result of a steep rise of rocks from the depths following a collision of two tectonic plates. This steep rise gives new insight into the final stage ... read more

Mar. 15, 2017 — Researchers have been studying the deep earthquake which occurred on May 30, 2015, to the west of Japan's Bonin ... read more

Mar. 6, 2017 — The Earth has known several mass extinctions over the course of its history. One of the most important happened at the Permian-Triassic boundary 250 million years ago. Over 95% of marine species ... read more

Mar. 2, 2017 — A new study suggests the mantle -- the mostly solid, rocky part of Earth's interior that lies between its super-heated core and its outer crustal layer -- may be hotter than previously believed. ... read more

Mar. 2, 2017 — One major mystery about life's origin is how phosphate became an essential building block of genetic and metabolic machinery in cells, given its poor accessibility on early Earth. Researchers ... read more

Mar. 2, 2017 — Researchers believe that it is possible for natural diamonds to form at the base of the Earth's mantle, giving new clues to what may be found in our planet's ... read more

Feb. 27, 2017 — Plate tectonics -- a defining feature of modern Earth and the driving force behind earthquakes, volcanoes and mid-ocean spreading ridges -- did not start until later in Earth's history, new ... read more

Feb. 27, 2017 — Seawater cycles throughout Earth's interior down to 2,900km, much deeper than previously thought, reopening questions about how the atmosphere and oceans ... read more

Feb. 23, 2017 — A study of tiny mineral 'inclusions' within diamonds from Botswana has shown that diamond crystals can take billions of years to grow. One diamond was found to contain silicate material ... read more

Feb. 22, 2017 — Plumbing a 90 million-year-old layer cake of sedimentary rock in Colorado, a team of scientists has found evidence confirming a critical theory of how the planets in our solar system behave in their ... read more

Feb. 22, 2017 — Scientists are reporting unexpected discoveries about Earth's core. The findings include insights into the source of energy driving Earth's magnetic field, factors governing the cooling of ... read more

Insight Into a Physical Phenomenon That Leads to Earthquakes

Feb. 22, 2017 — Researchers provide insight into a phenomenon called ageing that leads to more powerful ... read more

Feb. 21, 2017 — New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped ... read more

Feb. 20, 2017 — New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar ... read more

Feb. 17, 2017 — In bitter cold regions like northwestern Canada, permafrost has preserved relict ground-ice and vast glacial sedimentary stores in a quasi-stable state. These landscapes therefore retain a high ... read more

Feb. 15, 2017 — Bias introduced through analyzing the magnetism of old rocks may not be giving geophysicists an accurate idea of how Earth's magnetic dynamo has functioned. A team has shown there is a way to ... read more

Ancient Jars Found in Judea Reveal Earth's Magnetic Field Is Fluctuating, Not Diminishing

Feb. 14, 2017 — Surprising new evidence derived from ancient ceramics proves that the Earth's geomagnetic force fluctuates -- not diminishes -- over time, researchers ... read more

Feb. 14, 2017 — The fault under Ventura, California, would likely cause stronger shaking during an earthquake and more damage than previously suspected, researchers warn. The Ventura-Pitas Point fault in Southern ... read more

Seismicity in British Columbia and Hidden Continent Called Zealandia

Feb. 14, 2017 — Seismicity in the Pacific Northwest is well documented and includes recent seismic activity on fault systems within the Juan de Fuca Strait. However, the seismic potential of crustal faults within ... read more

Feb. 13, 2017 — Even though it is hotter than the surface of the Sun, the crystallized iron core of the Earth remains solid. A new study may finally settle a longstanding debate over how that's possible, as ... read more
