Thigpen suggests that river erosion may cause parts of the Earth's crust to move more quickly, resulting in large earthquakes far from plate boundaries, such as in Eastern Tennessee, where a 4.4 magnitude earthquake occurred just last week.
Ryan Thigpen, an assistant professor in the Department of Earth and Environmental Sciences in the University of Kentucky College of Arts and Sciences, has co-authored a paper that describes how river erosion may lead to more earthquakes.
The paper, which published this summer in the Journal of Geophysical Research, was featured in Scientific American this week.
Working with Sean Gallen from Colorado State University, the geologists suggest that removing so much weight from the
