Global Seismicity and World Cities--Map showing major earthquake epicenters and their relationship to world cities. Use this map to teach and learn about the distribution and frequency of earthquakes, comparing the earthquakes to the distribution of land masses, oceans, and cities/population. What cities are most at risk from earthquakes? How does your own city compare to others in terms of earthquake risk? On this map, over 39,000 earthquakes are shown with more than 8,300 cities.
