NASA Study Connects Southern California, Mexico Faults
Oct 09, 2018 (JPL)
Knowing how faults are connected helps scientists understand how stress transfers between faults. Ultimately, this helps researchers understand whether an earth...
Plate tectonics may have been active on Earth since the very beginning
Oct 09, 2018 (SPX)
The paper, published in Earth and Planetary Science Letters, has important implications in the fields of geochemistry and geophysics. For example, a better unde...
A wrench in Earth's engine
Oct 04, 2018 (SPX)
In a study online in Nature Geoscience, the team explored the physics of "stagnant slabs." These geophysical oddities form when huge chunks of Earth's oceanic p...
Geoscientists find unexpected 'deep creep' near San Andreas, San Jacinto faults
Sep 26, 2018 (SPX)
The new understanding should support more refined assessments of fault loading and earthquake rupture risk in the region, they add. Writing in the current onlin...
Britain formed from three colliding continental land masses, not two
Sep 14, 2018 (UPI)
But new research by geologists at the University of Plymouth suggests England, Wales and Scotland were formed by a collision among three landmasses. Armorica wa...
Central California is sinking at an accelerated rate
Aug 30, 2018 (UPI)
Between October 2011 and September 2015, California experienced its driest four-year spell since scientists began tracking precipitation totals in 1895. Heavy r...
New Antarctic rift data has implications for volcanic evolution
Aug 24, 2018 (SPX)
In a study published in Nature Communications, Dr. Roi Granot of BGU's Department of Geological and Environmental Sciences, and Dr. Jerome Dyment from the Insti...
Why multiple earthquakes are rattling one Indonesian island
Aug 20, 2018 (AFP)
The archipelago nation sits on the so-called Pacific "Ring of Fire", where tectonic plates collide and many of the world's volcanic eruptions and earthquakes oc...
New model reveals rips in Earth's mantle layer below southern Tibet
Aug 06, 2018 (SPX)
The specifics of the deep geologic processes that occurred roughly 50 million years ago, when the Indian and Asian tectonics plates collided, have remained elus...
Plate tectonics not needed to sustain life
Jul 31, 2018 (SPX)
When searching for habitable planets or life on other planets, scientists look for biosignatures of atmospheric carbon dioxide. On Earth, atmospheric carbon dio...
UMass Amherst geoscientists offer new evidence for how the Adirondack Mountains formed
Jun 28, 2018 (SPX)
Now, using an advanced seismic imaging method and data available only in the past five years, they have constructed a detailed model of the tectonic plate - the...
Granite crystallizes at temperature 200 degrees lower than previously thought
Jun 28, 2018 (SPX)
"In making predictions, geologists have relied on a crystallization temperature for granite that was established more than half a century ago, using the best to...
New insight into Earth's crust, mantle and outer core interactions
Jun 11, 2018 (SPX)
Using previously unavailable data, researchers confirm a correlation between the movement of plate tectonics on the Earth's surface, the flow of mantle above th...
Flow in the asthenosphere drags tectonic plates along
May 30, 2018 (SPX)
That's one conclusion from a new study by Rice University geophysicists who modeled flow in the 100-mile-thick layer of mantle that begins at the base of Earth'...
Continental growth spurt spurred Earth's first snow, study suggests
May 25, 2018 (UPI)
The link between rising coastal elevations and the planet's first snowflakes -- detailed this week in the journal Nature -- was revealed by isotopic analysis of...
Cold production of new seafloor
May 25, 2018 (SPX)
Very often, these mid-ocean ridges are described as a huge, elongated volcano. But this image is only partly correct, because the material forming the new seafl...
Ohio professor identifies hidden clues to ancient supercontinents, confirms Pannotia
Apr 05, 2018 (SPX)
Dr. Damian Nance, Distinguished Professor of Geological Sciences, said the supercontinent cycle is known to have had a profound influence on the course of Earth...
ANU scientists helping to improve understanding of plate tectonics
Mar 16, 2018 (SPX)
Research team leader Professor Ian Jackson said tectonic plates were continuously created at mid-ocean ridges and destroyed when they sink back into the Earth's...
Another clue for fast motion of the Hawaiian hotspot
Mar 05, 2018 (SPX)
This concept was initially proposed for the Hawaiian Islands. They are the youngest end of the Hawaiian-Emperor chain that lies beneath the Northwest Pacific. B...
Continental interiors may not be as tectonically stable as geologists think
Feb 21, 2018 (SPX)
The most ancient rocks on Earth are located within continental interiors, far from active tectonic boundaries where rocks recycle back into the planet's interio...
