Supercontinent Aggregation and Dispersal (1988) CaltechGeodynamics 695 views This movie shows what could potentially happen in the Earth's mantle as a large supercontinent moves around the surface. The non-subducting continent is shown by the green ...
Plate-mantle coupling and continental flooding (1990) CaltechGeodynamics 716 views This animation shows what would happen to the topography of a continent and relative sea level change as the continental plate interacted with mantle convection. More detai...
Examples of stirring by mantle convection (1991) CaltechGeodynamics 524 views This animation shows the evolution of passive tracers which are stirred by a simple, but plausible, model of time dependent mantle convection associated with plate tectonic...
Dynamic models of Tectonic Plates and Convection (1994) CaltechGeodynamics 3,685 views This is an animation of thermal convection with a strong temperature and stress dependent rheology in which perfect tectonic plates develop. More details at http://www.gps....
Dynamic Model of an Oceanic Plate with 3D Faults (1996) CaltechGeodynamics 404 views This animation shows a set of models created in collaboration with Dr. Shijie Zhong (U. Colorado, Boulder) that simulates the evolution of an oceanic plate in 3D. The uniqu...
The Ups and Downs of Australia (1998) CaltechGeodynamics 312 views This movie shows what happens to the surface of the Earth in the vicinity of Australia from the Early Cretaceous to the present. Find our more about the science behind the ...
Demise of the Farallon Plate Beneath North America (2001) CaltechGeodynamics 952 views Former Caltech postdoc Lijie Han and graduate student Eh Tan, working with Michael Gurnis, formulated a regional spherical model of the subduction of the Farallon Plate ben...
Superplume Formation Beneath an Ancient Slab (2001) CaltechGeodynamics 670 views Caltech graduate student Eh Tan, working with Dr. Michael Gurnis, has recently discovered a plausible mechanism of generating superplumes at the core mantle boundary. This ...
The Initiation of Subduction at an Old Fracture Zone (2002) CaltechGeodynamics 372 views Caltech postdoc Chad Hall, working with Dr. Michael Gurnis and Luc Lavier, has recently discovered a mechanism for initiating an entirely new subduction zone, perhaps the m...
Multiple models of convection (CitcomS) coupled with Pyre CaltechGeodynamics 208 views "An example of multiple models of convection (CitcomS) coupled with the Pyre framework" (2004) by Eh Tan et al. Find out more at our paper http://www.gps.caltech.edu/~gurni...

About this user

At Caltech's Seismological Laboratory, a wide range of research in computational geodynamics is carried out under the direction of Professor Michael Gurnis. The primary goal of the current work is to provide a basis for the sound interpretation of seismological observations made on local, regional, and global scales. Ultimately, we hope to fully understand how plate tectonics works, how plate tectonics and deep mantle flow are related, how and why mantle convection evolves over long time periods, and how continental geology is related to mantle dynamics. A primary, but not exclusive, activity for researchers within this area is the development of sophisticated numerical models of tectonic processes which are then related to geological and geophysical observations.
