The staff and students who make up the Seismology, Geology and Tectonophysics (SG&T) Division are part of a long tradition in the solid earth sciences at Lamont. SG&T researchers are at the forefront of theoretical and observational seismology, solid earth dynamics, rock mechanics, structural geology and tectonics, and sedimentary geology, and are making lasting contributions to the study of earthquakes, the structure of the Earth’s crust, mantle, and core, and the large-scale motions and deformation of the tectonic plates. The breadth of our work includes theory, observation and computation. SG&T scientists also serve the nation and the world by pursuing applied research and providing advice to national and international organizations in two critical areas: reducing society's vulnerability to natural hazards, and verifying international treaties governing nuclear weapons testing > more

Earthquakes and Faulting

SG&T scientists employ a broad spectrum of tools and techniques to develop a better understanding of the mechanics and dynamics of earthquakes and faulting.  These techniques include labor
