Pacific plate is scored by large undersea faults that are pulling it apart

A team of geoscientists from the University of Toronto is shedding new light on the century-old model of plate tectonics, which suggests the plates covering the ocean floors are rigid as they move across the Earth.

Iceland eruption confirms faultline has reawakened

A volcanic eruption that has engulfed homes in an Icelandic fishing port confirms that a long-dormant faultline running under the country has woken up, threatening to belch out lava with little warning for years to come.

Venus' ancient Earth-like plate tectonics

A recent study suggests that Venus, typically viewed as a fiery wasteland, may have experienced Earth-like plate tectonics in its distant past.

There's a Weird Deformation in Earth's Crust, And We May Finally Know Why

Earth's largest continental rift, the East African Rift (EAR) system, has been something of a mystery for geologists – but a new study combining computer models with GPS satellite data appears to have found an explanation.

The Science of The Devastating Turkey-Syria Earthquake

Turkey lies at the intersection of three of the tectonic plates that make up the Earth's crust: the Anatolian, Arabian, and African plates. Arabia is moving northwards into Europe, causing the Anatolian plate to be pushed out westwards.

Earth Has a 27.5-Million-Year 'Heartbeat'

A new study of ancient geological events suggests that our planet has a slow, steady 'heartbeat' of geological activity every 27 million years or so. But we dont' know what causes it. 

The Evolution Our Dynamic Planet In 40 Sec: Video

Geoscientists have released a video that for the first time shows the uninterrupted movement of the Earth’s tectonic plates over the past billion years. On a human timescale however - things move in cm per year.

Tectonic plates reverse their movement before major earthquakes

Researchers have discovered an interesting similarity in two of the largest recent earthquakes in Japan and Chile: a strange large-scale ground movement back and forth in the months leading up to the quake.

The Mystery of the Worldwide Humming Noise Uncovered

In 2018, a large number of seismic alerts had been detected everywhere. They created a weird buzzing sound. Now the mysterious hum is identified as rumblings of a magma-filled reservoir deep under the Indian ocean where the new volcano is forming. 

What happens under the Yellowstone Volcano

Recent study shows that beneath the Yellowstone volcano lies a so-called mantle plume: a chimney-like structure that reaches thousands of kilometres deep to the border of the Earth's core and mantle.

Kenya is splitting

A tear opens up in Kenya's Rift Valley. Geologists say it will - in a few million years - lead to the continent splitting in two.

There's a Jet Stream Churning in the Earth's Core

Satellite observations of the Earth's magnetic field reveal a fast-moving stream of metal deep inside the planet.

A Chunk of India and Eurasia Just Disappeared

Half of the original mass of India and Eurasia is missing, upending how geologists believed tectonic interactions worked.

Study: Ancient tectonic activity was trigger for ice ages

Continental shifting may have acted as a natural mechanism for extreme carbon sequestration.

New study zeros in on plate tectonics' start date: Analysis of trace elements places the onset of plate tectonics about 3 billion years ago

A new study suggests that plate tectonics -- the dynamic processes that formed Earth's mountains, volcanoes and continents -- began about 3 billion years ago. By analyzing trace element ratios that correlate to magnesium content in ancient Earth's crust, the researchers provide first-order geochemical evidence for when plate tectonics first got underway.
