Ved Lekic, Ph.D, a seismologist at the University of Maryland, will give a talk on "Imaging Tectonic Plates -- Structure and Deformation of North America" at 4 p.m. Thursday, April 9, in room 128 of the Montana Tech Natural Resources Building.
Lekic is an EarthScope Distinguished Speaker.
The outermost layer of the Earth is broken into tectonic plates whose relative motions cause earthquakes and volcanism. Much of what we know about the structure of these plates comes from studying the Earth’s surface. Seismic waves recorded by the EarthScope Transportable Array, however, show the internal structure of plates down to 200 km deep and help people understand the relationship between deep structure and the Earth’s surface. EarthScope images for the western United States hint at the presence of mid-depth discontinuities. To better understand these features, Lekic will relate them to the geologic history of the west.
His main scientific interests are the state, dynamics, and dominant processes of the solid Earth as well as those of other planets and satellites. The main focus of his research is developing higher resolution imaging techniques and obtaining more reliable constraints on structures in the Earth’s deep interior.
