Seismology, Geology, & Tectonophysics

Continental margins are the Earth's principal loci for producing hydrocarbon and metal resources, for earthquake, landslide, volcanic and climatic hazards, and for

Lamont has been a pioneer in the design, deployment, and utilization of global seismographic networks.  This document details an early study of long period seismograph calibrations.

Earthquakes in Greater New York-Philadelphia Area: Catalog 1677 to 2005 and Tectonic Setting

Lamont scientists utilize a variety of observational and computational techniques to image and model the deep interior of the Earth, from crust to core.

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

Geodynamics research in SG&T is focused on understanding the forces that drive deformation and tectonism in the solid Earth, and the role that rock rheology, physical state (solid or partially

Our faculty and staff engage in research projects that include the processes of continental deformation, fault growth, normal faulting, sedimentary layering patterns, Neoproterozoic Earth history,

Earthquakes, volcanoes, landslides, floods, drought, cyclones and other natural hazards have significant potential to affect human lives and society.

Our Ocean Bottom Seismology (OBS) Laboratory develops and operates cutting-edge instrumentation for measuring deformation of the ocean floor in a variety of experimental settings.  One of our
