New Animation! A Brief History of Plate Tectonics

The theory of plate tectonics represents a fairly young science. This animation gives an overview of the most-recognized proponents (and opponents) of Plate Tectonics Theory from the 1600's into the 1960's.

Highlights from the Field

Highlights from the Field

Students from UNR conduct geophysical research on a former nuclear test site using 30 Texans with 4.5 Hz vertical geophones from the PASSCAL Instrument Center. Using this equipment the class recorded two deep refraction microtremor arrays 2 km long, centered across ground zero.
Seismic Reawakening along the South-Central Chile Megathrust Boundary

Seismic Reawakening along the South-Central Chile Megathrust Boundary

Using GPS to examine regional changes in the earth’s surface with time, and seismology to understand the rupture process and stress changes associated with nearby earthquakes, researchers are seeking to understand the “reawakening” of the megathrust boundary along the west coast of Chile.
By road, boat, plane and helicopter: Creating a remote seismic measurement network

By road, boat, plane and helicopter: Creating a remote seismic measurement network

The Southern Alaska Lithosphere and Mantle Observation Network (SALMON) is a two-year EarthScope FlexArray project. Using data recorded by 28 of PASSCAL’s broadband seismometers, the goal is to produce images of the crust and upper mantle to better understand active faulting, mantle flow and seismic structure in the Cook Inlet region.
