From Earth's deep mantle, scientists find a new way volcanoes form
May 23, 2019 (SPX)
Scientists have long known that volcanoes form when tectonic plates (traveling on top of the Earth's mantle) converge, or as the result of mantle plumes that ri...
Monitoring Earth's shifting land
May 20, 2019 (ESA)
Land subsidence is the lowering or sinking of the ground's surface, owing to changes that take place underground. Subsidence is usually due to a combination of ...
Geologists find new way volcanoes form from material in mantle's transition zone
May 16, 2019 (UPI)
While studying the planet's layers deep beneath Bermuda, scientists found evidence of volcanic material rising from the mantle's transition zone, located 250 to...
Scientists call for better research on planetary internal dynamics
May 06, 2019 (UPI)
An international group of planetary scientists, geologists and chemists published a letter in the journal Science calling for more researchers to explore the ro...
Princeton geoscientists find new fallout from 'the collision that changed the world'
Apr 29, 2019 (SPX)
"These results are different from anything people have previously seen," said Emma Kast, a graduate student in geosciences and the lead author on a paper coming...
A first glimpse deep beneath an ultraslow-spreading mid-ocean ridge
Mar 27, 2019 (SPX)
Wegener's insight eventually led to the understanding, many decades and much debate later, that the Earth is made of plates that fit together like the cracked s...
The largest delta plain in Earth's history
Mar 27, 2019 (SPX)
And although contenders are found in the rock record, no ancient counterpart exceeds the extent of the Triassic delta plain mapped in the subsurface Barents Sea...
Earth's deep mantle flows dynamically
Mar 27, 2019 (SPX)
The discovery answers long-standing questions on the nature and mechanisms of mantle flow in the inaccessible part of deep Earth. This is key to understanding h...
Tide gauges capture tremor episodes in Cascadian subduction zone
Feb 18, 2019 (SPX)
Global Positioning System (GPS) data are typically used to measure uplift from these events, but the new findings offer a way to study the phenomena using tidal...
Massive Bolivian quake reveals mountains 660 kilometers below our feet

Fate of the subducted oceanic crust revealed by laboratory experiments
Feb 07, 2019 (SPX)
Using a combination of ultrasonic techniques and a large volume press apparatus, GRC researchers were successful in measuring the sound velocities of CaSiO3 per...
Earth's continental nurseries discovered beneath mountains
Jan 30, 2019 (SPX)

Scientists reconstruct ancient lost plates under Andes mountains
Jan 24, 2019 (SPX)
The Andean margin, where two tectonic plates meet, has long been considered the textbook example of a steady, continuous subduction event, where one plate slipp...
Why Tehran is sinking dangerously
Dec 07, 2018 (SPX)
In addition, the government built a lot of dams to store water for specific purposes, particularly in agriculture. However, this restricted the natural inflow i...
New study reveals connection between climate, life and the movement of continents
Nov 16, 2018 (SPX)
The study, published Nov. 15 in Earth and Planetary Science Letters, describes how sediment moving under or subducting beneath tectonic plates could regulate th...

Oct 31, 2018 (UPI)
Researcher Shuhei Yamamoto believes a beetle trapped in piece of Burmese amber from 99 million years ago is the distant ancestor to insects found on the other s...
Mexico's 2017 Tehuantepec quake suggests a new worry
Oct 26, 2018 (SPX)
