The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere. (This includes ...

This study is led by Prof. Yong-Fei Zheng at University of Science and Technology of China. It focuses on the development of tectonic processes along convergent plate margins through inspection of ...

Before I retired, I would often take school groups on tours of the HSU Geology Department’s seismograph. We’d start out in front of the drum on display in Van Matre Hall and talk about how ...

A new active fault system has been discovered off the coast of Portugal, which scientists believe could be the first signs of an eventual convergence of the North American and Eurasian tectonic plates ...
