UNL Geophysics Group


The Geophysics Research Group exists at the Department of Earth and Atmospheric Sciences since August 2016. Unlike many other geophysical research programs that focus on application or development of a single geophysical method, our group, led by Dr. Irina Filina, utilizes the integrative approach in geophysical data analysis. We are looking for the answer (i.e. geological model of the subsurface) that fits ALL available geophysical data and remains geologically valid. The data we use include seismic (reflections, refractions, earthquakes), gravity and magnetics both from public domain sources, as well as acquired by our own instruments.


Our group conducts research in several major directions:

  • Tectonic history of the Gulf of Mexico
  • Geophysical studies in Nebraska
  • Crustal structures of the Cascadia subduction zone
  • Investigating the continental status of Zealandia
