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.

New Animation! Plate Boundaries and Tectonic Plates

The cool, rigid, outer layer of the earth, the lithosphere, is broken into massive plates along discrete boundaries. What are these plates, and what do the boundaries represent?

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.
Detecting wind using seismometers

Detecting wind using seismometers

This research team is using seismometers to detect winds (both sustained winds and gusts) across a range of geographical settings.
