III.1 Tectonic Movements and Earthquake Hazard Predictions
Scientists from the UNAVCO Consortium in Boulder, Colorado, and at Indiana University in Bloomington, Indiana, created Jules Verne Voyager, a precision interactive map tool. This tool allows users to create “maps on demand” using wide ranges of base maps, geophysical overlays, and geographical information. Created by geophysicists Michael W. Hamburger and Charles Meertens, and graphic designer Elisha F. Hardy, the seismic hazard map shown here was derived from the International Lithosphere Program and the Global Seismic Hazard Assessment Program. It uses a model built from historical seismicity catalogs and 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 show the topographic, seismologic, 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.
