Paleostress modeling shows how a region of the Andean Plateau was uplifted and formed beginning more than 20 million years ago.

Subduction zones, where one tectonic plate dives underneath another, drive the world’s most devastating earthquakes and tsunamis. How do these danger zones come to be? A study in Geology presents ...

Andes reach for the rain, says geologist Irregular rainfall distribution over the past ten million years has influenced the shape of the Andes mountain range, according to a Swiss geology professor.

"The Andes Mountain formation has long been a paradigm of plate tectonics," study co-author Jonny Wu, assistant professor of geology at the University of Houston, said in a statement.

Most college students don't even consider geology, but they're missing out on the whole planet!

Geoscientists have discovered accumulations of magma in the Andes sufficient to have set off a super-eruption but which, in fact, did not. Such eruptions, which expel enormous quantities of magma ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

A flurry of seismic activity that caused 160 quakes in just two hours at the Laguna del Maule volcanic field in central Chile has put authorities on alert. 160 quakes occurred in the area during a ...

The July issue of Geology presents several studies on various aspects of temperature and climate change; a new river dataset examining whether the sedimentological record can help document floods ...

Irregular rainfall distribution over the past ten million years has influenced the shape of the Andes mountain range, according to a Swiss geology professor. The result is that the western side of ...
