Why the 'uplift of the Tibetan plateau' is a myth
May 12, 2020 (SPX)
The orogeny of the Tibetan region (Tibet, The Himalaya and the Hengduan Mountains) dates back approximately 200 million years, long before the arrival of India,...
Does accelerated subduction precede great earthquakes
May 01, 2020 (SPX)
Together with a diverse team of geoscientists from GFZ, FU Berlin, Chile, and USA, he investigated signals recorded in Chile and Japan capturing the movement of...
Map of tectonic stresses in North America could help assess tremor risk
Apr 23, 2020 (UPI)
In the short term, the map of North American faults -- published Thursday in the journal Nature Communications -- could help scientists assess the risk of major...
Tectonic plates started shifting earlier than previously thought
Apr 23, 2020 (SPX)
A research team led by Harvard researchers looked for clues in ancient rocks (older than 3 billion years) from Australia and South Africa, and found that these ...
Wits researchers unravel the mystery of non-cotectic magmatic rocks
Apr 03, 2020 (SPX)
The question is that of how certain magmatic rocks that are formed through crystallisation in magmatic chambers in the Earth's crust, defy the norm, and contain...
Shifts in deep geologic structure may have magnified great 2011 Japan tsunami
Mar 17, 2020 (SPX)
The tsunami's obvious cause: the quake occurred in a subduction zone, where the tectonic plate underlying the Pacific Ocean was trying to slide under the adjoin...
Sinking sea mountains make and muffle earthquakes
Mar 04, 2020 (SPX)
The findings mean that scientists should more carefully monitor particular areas around a subducting seamount, researchers said. The practice could help scienti...
Quantum mechanical simulations of Earth's lower mantle minerals
Mar 04, 2020 (SPX)
It is now possible to predict stability, elasticity, and transport properties of complex minerals quantitatively with uncertainties that are comparable or even ...
Climate change could trigger more landslides in high mountain Asia
Feb 17, 2020 (SPX)
High Mountain Asia stores more fresh water in its snow and glaciers than any place on Earth outside the poles, and more than a billion people rely on it for dri...
Expedition reveals the violent birth of Earth's hidden continent Zealandia, forged in a ring of fire
Feb 07, 2020 (The Conversation)
Now, newly published results from our scientific drilling expedition reveal the largely submerged Zealandia continent, which stretches across five million squar...
Viscosity measurements offer new insights into the earth's mantle
Feb 04, 2020 (SPX)
The data obtained support the assumption that a bridgmanite-enriched rock layer was formed during the early history of the earth at a depth of around 1,000 kilo...
New insights into the formation of Earth's crust
Dec 30, 2019 (SPX)
In a paper published in the journal Science Advances, Ibanez-Mejia and Tissot studied the isotopes of the element zirconium. Most elements in the periodic table...
Extra-terrestrial impacts may have triggered 'bursts' of plate tectonics
Nov 27, 2019 (SPX)
"We tend to think of the Earth as an isolated system, where only internal processes matter," says Craig O'Neill, director of Macquarie University's Planetary Re...
What makes the Earth's surface move?
Oct 31, 2019 (SPX)
According to their simulations, published in Science Advances on October 30, 2019, it is mainly the surface that drives the mantle, although the dynamic balance...
Why are mountains so high?
Sep 24, 2019 (SPX)
Scientists have long assumed that as land is pushed faster upward to form a mountain, its height increases in a continuous and predictable way. But new research...
What drives plate tectonics?
Sep 05, 2019 (SPX)
However, it is not like the widely accepted kinematics of plate tectonics, the driving force of plate tectonics is still one of the most challenging problems si...
Crack in Pacific seafloor caused volcanic chain to go dormant
Aug 27, 2019 (SPX)
At the end of the Cretaceous Period, shortly after dinosaurs disappeared, the Pacific Plate, the largest tectonic plate on Earth, mysteriously changed direction...
New model suggests lost continents for early Earth
Jul 08, 2019 (SPX)
Scientists at the University of Adelaide have published two studies on a model of rock radioactivity over billions of years which found that the Earth's contine...
Continents on early Earth rose from the sea, then disappeared
Jul 01, 2019 (UPI)
Researchers in Australia designed the model of rock radioactivity to better understand the history of Earth's crust. Simulations showed Earth's crust was much t...
Plate tectonics may have triggered Cambrian explosion
Jun 20, 2019 (UPI)
The Cambrian explosion began 500 million years ago and lasted just 13 million years. During the period, almost all major animal phyla emerged. For decades, scie...
