Dr. Michael W. Hamburger and his colleagues from the UNAVCO Consortium in Boulder, Colorado created Jules Verne Voyager, a precision interactive map tool for the virtual exploration of Earth and other worlds.

Description of Unique Features: The online browser interface at jules.unavco.org allows users to create “maps on demand” using wide ranges of base maps, geophysical overlays, and geographical information.

Data Used: The seismic hazard map shown here was derived from the Global Seismic Hazard Assessment Program using a model of historical seismicity catalogs, geologic and geodetic data to predict the frequency, location, and magnitude of earthquakes. Seismic hazard is represented in probabilistic fashion, as the peak ground acceleration (in meters/second2) with a 10% chance of exceedance in a 50 year period.

The inset maps along the bottom of the map show the topographic, seismological, volcanic, and tectonic data for several of the major seismically active plate boundaries that comprise the “Ring of Fire” surrounding Asia, Europe, North and South America, and the western Pacific. Arrows indicate the inferred direction of motion of the Earth’s crust with respect to an arbitrarily “fixed” plate at the center of each map. Note the intense concentration of seismic and volcanic activity near the boundaries and the few anomalous zones within the interior of Earth’s tectonic plates.
