Tantalizing Tectonics: Monstrous “Claw Mark” Scratches on the Surface of Mars
This network of long grooves and scratches forms part of a giant fault system on Mars known as Tantalus Fossae, and is shown here as…

On the micrometer scale deformation properties of metals change profoundly: the smooth and continuous behavior of bulk materials often becomes jerky due to random strain…
Earthquakes themselves affect the movement of Earth’s tectonic plates, which in turn could impact on future earthquakes, according to new research from the University of…
By analyzing the chemistry of over 200 geothermal springs, researchers have identified where the Indian Plate ends beneath Tibet, debunking some long-debated theories about the…
Every geography schoolbook has them: maps that look like today’s Earth, but not quite, since all continents are merged into a single supercontinent. Those maps…
Ice action seems responsible for ancient erosion of rock across the planet. New research provides further evidence that rocks representing up to a billion years…
New Curtin University research has confirmed the frequency of asteroid collisions that formed impact craters on Mars has been consistent over the past 600 million…
A simulation of the evolution of the Earth’s interior over time, showing the thermal (bottom), chemical (middle), and thermochemical evolution under the simulated conditions. The…
Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis….
Our world’s surface is a jumble of jostling tectonic plates, with new ones emerging as others are pulled under. The ongoing cycle keeps our continents…
Planets without plate tectonics are unlikely to be habitable. But currently, we’ve never seen the surface of an exoplanet to determine if plate tectonics are…
Strange ‘eggshell planets’ are among the rich variety of exoplanets possible, according to a study from Washington University in St. Louis. These rocky worlds have…
Washington Irving’s classic tale about a headless horseman plays out an ancient landscape scarred by tectonic collisions and the relentless forces of erosion. In 1798,…
Multidisciplinary team of materials physicists and geophysicists combine theoretical predictions, simulations, and seismic tomography to find spin transition in the Earth’s mantle. The interior of…
Assistant professors Camilla Cattania and William Frank discuss the science behind the 2010 and 2021 earthquakes in Haiti. On August 14, 2021, a magnitude 7.2…
One of Earth’s unique features is that it has continents. Contrary to many theories, the continents have always been rich in silica (which is found…
A new study led by the University of Colorado Boulder reveals the complex history behind one of the Grand Canyon’s most well-known geologic features: A…
Scientists from Cambridge University and NTU Singapore have found that slow-motion collisions of tectonic plates drag more carbon into Earth’s interior than previously thought. They…
