Additional evidence surfaced in Palawan, an island in the western Philippines, and the South China Sea. These discoveries suggest that the Pontus plate was once part of a unified tectonic system ...

The origins of plate tectonics on Earth are hotly debated, but evidence from Australia now shows that parts of the crust ...

The second model was plate tectonics. On Earth, about 80 percent of volcanism occurs along mid-oceanic ridges where two tectonic plates are spreading apart and magma upwells.

A new method integrates Interferometric Synthetic Aperture Radar (InSAR) with conventional ground geodetic networks, taking us closer to high-resolution mapping of plate motions.

About 150 million years ago, a massive tectonic mega-plate stretched across the Earth, spanning roughly a quarter of the size of the Pacific Ocean. Its jagged contours ran all the way through the ...

Geologists from The University of Hong Kong (HKU) have made a breakthrough in understanding how the Earth’s early continents ...

A new study details how the North American plate is “dripping” into the mantle due to the continued influence of the Farallon Plate, which has been subducting under the continent for 200 ...

The Andes Mountains formed from the convergence of the Nazca plate and the South American plate. Aracar, seen in a satellite image from Feb. 20, 2000, is one of many volcanoes in the Andes range.

What causes earthquakes? Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other.
