The relationship between erosion and tectonics in the Himalayas
Aug 26, 2016 (SPX)
Earth's climate interacts with so called surface processes - such as landslides or river erosion - and tectonics to shape the landscape that we see. In some reg...
Japan scientists detect rare, deep-Earth tremor
Aug 25, 2016 (AFP)
Scientists who study earthquakes in Japan said Thursday they have detected a rare deep-Earth tremor for the first time and traced its location to a distant and ...
Recent connection between North and South America reaffirmed
Aug 19, 2016 (SPX)
Long ago, one great ocean flowed between North and South America. When the narrow Isthmus of Panama joined the continents about 3 million years ago, it also sep...
Researchers uncover 340M year-old oceanic crust in the Mediterranean Sea
Aug 17, 2016 (SPX)
A researcher at Ben-Gurion University of the Negev (BGU) has identified that the eastern Mediterranean Sea contains the world's oldest oceanic crust still in pl...
Scientists identify world's oldest oceanic crust in Mediterranean
Aug 15, 2016 (UPI)
The oldest oceanic crust on Earth lies at the bottom of the eastern Mediterranean in the Herodotus Basin, a seafloor depression north of Egypt and Libya. Roi Gr...
The search for the earthquake nucleus
Aug 04, 2016 (SPX)
Where a tectonic plate dives under another, in the so-called subduction zones at ocean margins, many strong earthquakes occur. Especially the earthquakes at sha...
Opposing mountain ranges
Aug 04, 2016 (SPX)
Different mountain ranges are bound to experience climate change differently. Researchers from ETH Zurich and Utrecht University have shown this to be the case ...
Earth's mantle appears to have a driving role in plate tectonics
Jul 29, 2016 (SPX)
Deep down below us is a tug of war moving at less than the speed of growing fingernails. Keeping your balance is not a concern, but how the movement happens has...
Huge time-lag between erosion and mountain building
Jul 21, 2016 (SPX)
An unprecedented record of erosion rates dating back millions of years shows a significant time-lag between tectonic uplift and maximum erosion rates in the Arg...
Continental tug-of-war - until the rope snaps
Jul 19, 2016 (SPX)
Present-day continents were shaped hundreds of millions of years ago as the supercontinent Pangaea broke apart. Derived from Pangaea's main fragments Gondwana a...
The pains and strains of a continental breakup
Jul 19, 2016 (SPX)
Every now and then in Earth's history, a pair of continents draws close enough to form one. There comes a time, however, when they must inevitably part ways. No...
New study upends a theory of how Earth's mantle flows
Jul 11, 2016 (SPX)
A new study carried out on the floor of Pacific Ocean provides the most detailed view yet of how the earth's mantle flows beneath the ocean's tectonic plates. T...
Plate tectonics without jerking
Jul 06, 2016 (SPX)
The earthquake distribution on ultraslow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometres ...
New analysis reveals large-scale motion around San Andreas Fault System
Jun 23, 2016 (SPX)
An array of GPS instruments near the San Andreas Fault System in Southern California detects constant motion of Earth's crust - sometimes large, sudden motion d...
Large-scale motion detected near San Andreas Fault System
Jun 20, 2016 (UPI)
Analysis of GPS data has revealed new areas of motion around the San Andreas Fault System. Using data collected by the EarthScope Plate Boundary Observatory's G...
Mounting tension in the Himalaya
Jun 15, 2016 (SPX)
The Gorkha earthquake struck Nepal on April 25, 2015. It's a part of the world that is prone to earthquakes, as the Indian plate makes its incremental, sticky d...
Toronto-led research suggests some major changes to geology textbooks
Jun 13, 2016 (SPX)
Super-computer modelling of Earth's crust and upper-mantle suggests that ancient geologic events may have left deep 'scars' that can come to life to play a role...
How a huge landslide shaped Zion National Park
May 27, 2016 (SPX)
A Utah mountainside collapsed 4,800 years ago in a gargantuan landslide known as a "rock avalanche," creating the flat floor of what is now Zion National Park b...
How the spectacular Hawaiian-Emperor seamount chain became so bendy
May 17, 2016 (SPX)
The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Syd...
Earth's upper mantle moving up and down 'like a yo-yo'
May 12, 2016 (SPX)
Researchers have compiled the first global set of observations of the movement of the Earth's mantle, the 3000-kilometre-thick layer of hot silicate rocks betwe...
