A number of institutions have jointly produced a Global Seismic Hazard map (Giardini, 1999). This map, although slightly outdated and of limited detail, can be obtained directly from the GSHAP project webite. From the NOAA's National Geophysical Data Center one can obtain a point map with all major earth quakes (Significant Earthquake Database; cca 5000 quakes), and generate a (kernel density) map for Earthquake magnitude (shown below).

University of Hawaii maintains a Global Hazards Information Network, which contains a number of global layers including a map of Global Airports, locations of significant earthquakes and earthquake zones.

NASA's Climate Center Lightning Team maintains a global map of Lightning Activity. The average yearly counts of lightning flashes per square kilometer based on data collected by NASA satellites between 1995 and 2002 can be obtained from here.
