'Tectonic Social Distancing Along the Denali Fault'
February 16, 2021
Sean Regan will present 鈥淭ectonic Social Distancing Along the Denali Fault鈥 at 7 p.m.
Tuesday, Feb. 23, as part of the the 麻豆原创 Geophysical Institute's
virtual 2021 Science for Alaska Lecture Series.or watch live from the 麻豆原创F or GI Facebook pages.
The Denali Fault is a long, tectonically active region that snakes through Alaska鈥檚 southern interior region. The fault marks the boundary where two portions of the North American Continental Plate grind past each other. Their convergence creates the iconic mountainous terrain of the Alaska Range and causes earthquakes whenever enough pressure builds up between the plates, such as the earth-shattering magnitude 7.9 quake of 2002.
Regan, assistant professor in the Department of Geosciences, will talk about igneous rocks in the Alaska Range and the techniques geologists use to determine their age. By carefully studying the geologic features along the Denali Fault, scientists are slowly unraveling the history of this iconic landscape and its role in shaping Alaska.
