Natural Hazard Maps


 Tsunami Sources   Significant Earthquakes   Significant Volcanic Eruptions

The ITIC and NOAA's National Geophysical Data Center (ICSU World Data Service for Geophysics, Marine Geology and Geophysics Division) have collaborated to produce global hazard maps for tsunamis, earthquakes, and volcanoes. The NGDC manages global geophysical, sea floor, and natural hazards data, including tsunamis, earthquakes, and volcanoes. 

The Tsunami Sources (English) poster was updated in 2010, 2011, 2014 and in Spanish in 2012.  The Earthquake and Volcano posters were updated in 2010 and 2013.  The Tsunami Sources Icosohedron was updated in 2010, 2012, 2014.
