Natural Hazards
Natural hazards such as earthquakes, tsunamis, and volcanoes affect both coastal and inland areas. Long-term data from these events, including photographs, can be used to establish the past record of natural hazard event occurrences. These data are also important for planning, response, and mitigation of future events. The National Geophysical Data Center plays a major role in post-event data collection. We also assist in the detection, location, and evaluation of the extent of certain hazards using satellite data. The types of hazards detected using the Defense Meteorological Satellite include fires, floods, hurricanes, and cyclones.
