There are hundreds of large earthquakes occurring globally every year, these earthquakes generate seismic waves that travel through the deep interior of the earth. Ground motions recorded by seismometers are the most direct observations on the Earth's interior for understanding the dynamics of the planet that are responsible for past tectonic events as well as present-day natural hazards including earthquakes and volcanoes. At Virginia Tech Global Seismological Lab, we study seismic wave propagation in complex earth media and seismic structure of the Earth's interior.
Seismic anisotropy at the top of the transition zone (390 km depth) in model FFSW1. Red indicates (active or frozen) seismic anisotropy corresponding to vertical mantle flow, whereas blue indicates horizontal mantle flow. Average grid spacing is 450 km.
