Freymueller is an internationally recognized expert in geodesy, or the study of Earth’s size and shape, and serves as MSU’s Endowed Chair for Geology of the Solid Earth. Jeffrey Freymueller, a professor in the College of Natural Science at Michigan State University, is researching this earthquake to learn more about exactly where that slip occurred (and how much) to better understand how faults work and to help evaluate the risk of future earthquakes and tsunamis. Between 20, the two plates slipped along this fault, producing a series of earthquakes, including the Chignik, Alaska, earthquake on July 29, 2021, which registered an 8.2 in magnitude - the largest earthquake within U.S. Off the coast of Alaska, the Pacific plate thrusts underneath the North American plate creating enormous pressure at the Alaska-Aleutian fault.
They may feature historical information, background, research findings or offer tips.Įarthquakes are caused by the movement of the tectonic plates that make up Earth’s crust. “Ask the Expert” articles provide information and insights from MSU scientists, researchers and scholars about national and global issues, complex research and general-interest subjects based on their areas of academic expertise and study.
