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.
 

SCIENCE AND PROGRAM HIGHLIGHTS

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.

Scientists Find Pre-Earthquake Activity in Central Alaska

Scientists Find Pre-Earthquake Activity in Central Alaska

 Researchers from the University of Alaska Fairbanks Geophysical Institute found evidence for accelerating activity before a 2016 earthquake in a laterally moving fault zone in central Alaska. The activity included a phenomenon known as very low-frequency earthquakes.
