Geologic imaging technique measures strength of Earth’s outer shell

An advanced imaging technique used to map Earth's outer shell also can provide a measure of strength, finding weak spots and magma upwellings that...

New technique for finding weakness in Earth’s crust

Scientists have developed a method to estimate weakness in Earth's outer layers which will help explain and predict volcanic activity and earthquakes. Published in the...

Seismic ‘CT scans’ reveal deep earth dynamics

A new look 100 miles beneath a massive tectonic plate as it dives under North America has helped clarify the subduction process that generates...

Revealing Earth’s early secrets

Addressing fundamental unknowns about the earliest history of Earth's crust, scientists have precisely dated the world's oldest rock unit at 4.02 billion years old....

Satellite radar image analysis reveals that rifting in Iceland exhibits simultaneous...

The separation of tectonic plates takes place over millions of years, often deep on the ocean floor. Geologists rarely get a chance to study...

Using magnetic data: Researcher uncovers 340 million year-old oceanic crust in...

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...

The search for the earthquake nucleus

Where a tectonic plate dives under another, in the so-called subduction zones at ocean margins, many strong earthquakes occur. Especially the earthquakes at shallow...

Earth’s mantle appears to have a driving role in plate tectonics

Deep down below us is a tug of war moving at less than the speed of growing fingernails. Keeping your balance is not a...

The strains of a continental breakup

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...

Plate tectonics without jerking

The earthquake distribution on ultraslow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometres leads...

Crystal movement under Mount St. Helens may have indicated 1980 eruption...

A study of how crystals moved in magma under the Mount Saint Helens volcano before the 1980 eruption may have signalled that an eruption...

Why do intracontinental basins subside longer?

Intracontinental basins like the North German Basin, the West Siberian Basin, the Barents Sea or the Congo Basin are large depressions of the Earth’s...

Understanding Volcanic Eruptions Where Plates Meet

A new project elucidates the relationships between tectonics and volcanic systems and how they influence hazards on Italy's Mount Etna and Vulcano and Lipari...

Oxygen atmosphere recipe = tectonics + continents + life

Earth scientists from Rice University, Yale University and the University of Tokyo are offering a new answer to the long-standing question of how our...

Found: Surviving evidence of Earth’s formative years

New work from a team including Carnegie's Hanika Rizo and Richard Carlson, as well as Richard Walker from the University of Maryland, has found...

How the spectacular Hawaiian-Emperor seamount chain became so bendy

The physical mechanism causing the unique, sharp bend in the Hawaiian-Emperor seamount chain has been uncovered in a collaboration between the University of Sydney...

Continental drift created biologically diverse coral reefs

Nowhere today is the biodiversity of corals and reef-inhabiting fish higher than in the tropical waters around Indonesia and its neighbouring countries in Southeast...

Supercontinent rift formed bizarre Bunbury rocks

Bunbury beachgoers may be unsettled to learn that the refreshing, blue stretch of water off the port city was preceded by a huge lava...

Ancient tectonic activity was trigger for ice ages, study says

For hundreds of millions of years, Earth's climate has remained on a fairly even keel, with some dramatic exceptions: Around 80 million years ago,...

Massive Ancient Tectonic Slab Found Below the Indian Ocean

A team of researchers recently discovered an ancient relic hidden within Earth: a tectonic plate resting beneath the southern Indian Ocean. Scientists have found...
