            "title": "Volumetric Visualization of the Convection-generated Stresses in Earth",
            "description": "The fundamental problem of the deformation of the Earth involves stress conditions on the basis of the crust caused by the mantle convection. Based on decades of satellite gravity data, a harmonic analytical model of the convection flow has been developed at GSFC. The magnitudes and directions of the resultant stresses in the crust were obtained at 64,000 grid points for each of 18 layers from 150 km to 600 km under the Earth. In this project, we explored three dimensional volumetric visualization methods for the data. To overcome the typical volumetric visualization obstacles such as enormous amount of data and opacity of objects in the scene, we developed an interactive and transparent isosurface model to render the volumetric data. a) Animated isosurfaces of earth stress below Hawaii. The blue objects indicate the shape of the stress distribution and the yellow objects indicate the high stress areas. b) Interactive global earth stress. To view the model, please use the QuickTime Player (similarly, please select the QuickTime version of the movie). Hold the left button and drag the mouse horizontally to view areas on the earth at the same depth. Hold the left button and drag the mouse vertically to view the different layers of the stress distributions inside the earth, between 150 km to 600 km deep. || ",

            "description": "In a new study, NASA and United States Geological Survey (USGS) scientists found that retreating glaciers in southern Alaska may be opening the way for future earthquakes. The study examined the likelihood of increased earthquake activity in southern Alaska as a result of rapidly melting glaciers. As glaciers melt they lighten the load on the Earth's crust. Tectonic plates, that are mobile pieces of the Earth's crust, can then move more freely, which increases the probability of earthquakes occurring in this region. || ",

            "description": "This animation shows a cumulative view of earthquake activity for the whole world from 1980 through 1995.  Each dot on the image represents the number of earthquakes with magnitude greater than 4.2 that have occurred in a 0.35 by 0.35 degree area of the globe since January 1, 1980.  A yellow dot represents 1 or 2 earthquakes, an orange dot represents about 10 earthquakes, and a red dot represents 50 to 200 earthquakes.  The background image, if present, shows the topography of the ocean floor.  As the animation proceeds, the earthquakes clearly accumulate around the topographic features that represent the boundaries of the Earth's crustal plates.  This animation is based on data from world-wide seismic networks and was obtained from the National Earthquake Center of the United States Geological Survey. || ",
