Crustal deformation and mantle dynamics research
Earth's mantle extends from the top of our planet's liquid core to the crust of its surface. CIRES scientists study this dynamic layer and its influence on plate tectonics and crustal deformation. Convection within the mantle is thought to occur at just a few centimeters per year, yet this motion causes continental plates to drift and collide, triggering earthquakes and fueling volcanic activity. Our researchers use seismology and geodesy to measure ground motion in places as far away as the Himalaya and as close as the Rocky Mountains. These tools allow us to map the deep structure of the earth and estimate future seismic hazards at plate boundaries.
