  2. Other Coastal Hazards: Nor’easter The Dolan-Davis Nor’easter Intensity Scale (Courtesy: www.mcwar.org) (Courtesy: NOAA) • Nor’easters are similar to hurricanes, but rotate in the opposite direction and occur more often in the winter time Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 1, Nor’easters

  3. Other Coastal Hazards: Hurricane and Nor’easter Related Storm Surge, High Wind, Torrential Rain, Severe Winter Weather, and Waterspout all can occur as a result of hurricanes or nor’easters.

  4. Other Coastal Hazards: Rip Current • Rip current is also a unique hazard in the coastal zone (Courtesy: NOAA) • A rip current from the air Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 3, Rip Current

  5. Impacts: Natural Environment • Natural disturbances from hazards have an effect on coastal ecosystems such as coral reefs and seagrass (Courtesy: John Bruno) Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 4, Environmental Impacts

  6. Impacts: Human Environment Disasters occur when the human built environment meets natural hazards Sandy beach/barrier island development (Courtesy: John Bruno) Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 5, Human Impacts

  7. Disasters: Hurricanes (Courtesy: NOAA Photo Library) (Courtesy: FEMA) On average, hurricanes kill 80 people per year in the US and Hurricane Andrew alone caused more than $25 billion in damages Session 7: Coastal Hazards II Coastal Hazards Management Course Slide 7. 6, Human Impacts due to Hurricanes
