A comprehensive study of faults along the north side of the Olympic Mountains of Washington State emphasizes the substantial seismic hazard to the northern Puget Lowland region. The study examined the ...

While it is often said that mountains don’t move, in reality, the Colorado Rocky Mountains are the result of a slow dance that has been occurring beneath the earth’s surface for hundreds of millions ...

Tectonic plates, big sections of Earth's crust and blocks underneath them, are constantly moving. The areas where these sections meet and interact are called faults. They appear as scars on the ...

The Atlas Mountains of Morocco are unusually high, given that only a moderate amount of faulting has helped to build the topography. Now, seismic images show that hot mantle is upwelling beneath the ...

200 million years of geological evolution of a fault in Earth’s crust has recently been dated. These new findings may be used to shed light on poorly understood pathways for methane release from the ...
