Division of Seismology, Geology and Tectonophysics


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

About B&PE

The Biology and Paleo Environment Division (B&PE) is a diverse group of oceanographers, geologists, geochemists, biologists and environmental scientists who pursue research in two connected efforts. First, we use biology (usually looking at fossils) to uncover clues about Earth’s past environment. We also strive to understand how the modern environment— through its oceans, atmosphere and land—affects present-day biology.











Anthropogenic Impacts on Terrestrial Ecosystems

view from Atigun PassHuman activities are significantly and rapidly altering the form and function of terrestrial ecosystems. For example, we are changing the chemical composition of the atmosphere, converting natural landscapes to urban areas, and transporting floral and faunal species far beyond their natural boundaries. Through both field and lab based experiments, we strive to gain a better understanding of how such anthropogenic changes impact ecosystems. Using a wide range of measurement techniques, our study foci vary in scale from individual leaves to entire ecosystems, Recently, we have included the response of resident fauna who depend upon vegetation for both food and habitat.
