Earth's Inconstant Magnetic Field

This article discusses our planet's magnetic field, which is in a constant state of change. The location of the North Pole has been moving north at an average speed of 10 km per year, lately ...

Superplume Formation Beneath An Ancient Slab

Graduate student Eh Tan, working with Michael Gurnis at the California Institute of Technology, has recently discovered a plausible mechanism of generating superplumes at the core mantle boundary. ...

The Superswell and Darwin Rise: Thermal No Longer?

This short online article, from the mantleplumes.org website, reviews the evidence for a thermal plume-related cause of the large shallow region in the western Pacific Ocean containing the Darwin ...

Superplumes from the core-mantle boundary to the base of the lithosphere: evidence from Q tomography

This page at the Berkeley Seismological Laboratory summarizes the recent results of imaging the superplume beneath the Pacific superswell region by the method of Q-tomography. The page includes ...

Convection Plumes in the Lower Mantle

This is the classic 1971 Nature paper in which W.J. Morgan proposed deep mantle plumes for the origin of hotspots.

"Hotspots": Mantle Thermal Plumes

This website features the chapter on hotspots and mantle plumes in the online text "This Dynamic Earth: The Story of Plate Tectonics", published by the U.S. ...

Rapid Earthquake Viewer

The Rapid Earthquake Viewer (REV) provides access to earthquake data from seismograph recording stations around the world. The Earthquake View lets users select an earthquake and see data at various ...

Hotspots: Mantle Thermal Plumes

This article discusses the idea of 'hot spot' volcanoes, those not associated with plate tectonic boundaries, but rather with relatively stationary sources of heat energy (thermal plumes) ...

Mantle Plumes

This site provides a broad suite of information and resources about "hot spots" and the current debate as to their existence. The site features technical tutorials and publications on a ...

Earth's Interior

This website contains class notes from a Geology 101 (physical geology) course. It discusses the composition and structure of the Earth's interior. Each layer, the inner core, outer core, ...

Convection Movies

This page, on the website of Stephane Labrosse of ENS Lyon, presents some examples of flow motions resulting from convection calculations in different situations. All are for infinite Prandtl number ...

Glacial Isostasy

This animation depicts the changes that occur in the mantle and crust when undergoing glacial isostasy. The animation covers both the thickening of the glacier and its subsequent melting.

Late Jurassic Tectonics and Paleogeography (145 Ma)

These side-by-side images from Northern Arizona University show tectonic conditions of Western margin of North America alongside a paleotopography map.

Subducting Farallon Plate under North America

Three-dimensional seismic tomography image showing the subducting farallon plate beneath the crust of western North America. Part of Princeton University's 'Art of Science 2009' ...

Plate Tectonics and the Evolution of Central America and the Caribbean

A series of illustrations with explanatory text from the University of Wisconsin-Green Bay showing the tectonic evolution of Central America and the Caribbean region from 170 Ma to present.

Mantle convection currents and plate motions

This page from the University of Nebraska, Omaha, investigates the connection between mantle convection and plate tectonics. Topics discussed (with illustrations) include convection geometries, hot ...

Dynamic Earth - Mantle Convection

This page from the University of Leeds gives an introduction to the drivers of plate tectonics, including links to illustrations depicting ridge push/ slab pull, ridge bathymetry, mantle tomographic ...

Mantle Convection Cell

An annotated illustration showing mantle convection and its relation to plate tectonics, from the Byrd Polar Research Center at Ohio State University.

Geodynamo

This page from UC-Santa Cruz gives a description of the Earth's geomagnetic history, with several modeled images of the Earth's magnetic field. Included is a link to a PBS Nova animation of ...

Mantle Convection Modeling

This research page provides links to two animations of modeled mantle convection, showing the progression of convection over millions of years. There are also links to other work and publications by ...
