Coastal Disaster Contrasts
America's Atlantic and Pacific coasts face distinctly different natural disaster threats shaped by regional geology, oceanography, and climate patterns.
West Coast Hazards
The Pacific Coast faces earthquake, tsunami, and wildfire hazards. California's active tectonics create frequent seismic activity. Subduction zones (Cascadia, San Andreas) pose megathrust earthquake risks. Wildfires intensify due to arid conditions and vegetation. Tsunamis from distant earthquakes or local submarine earthquakes present a secondary hazard.
East Coast Hazards
The Atlantic Coast faces hurricane, nor'easter, and flood hazards. Tropical cyclones dominate from June-November. Nor'easters bring winter storm surge and wind damage December-April. Sea level rise amplifies storm surge impacts, creating significant concern for cities like Miami, New York, and Boston.
Frequency Comparison
The West Coast averages 3-4 billion-dollar events annually, primarily from wildfires and earthquakes. The East Coast averages 5-6 billion-dollar events annually, primarily from hurricanes and nor'easters. The East Coast has experienced more billion-dollar hurricane events than the West Coast has experienced billion-dollar earthquakes in recent decades.
Infrastructure Impact
West Coast infrastructure adapts to seismic hazards through building codes. East Coast infrastructure focuses on water management and storm-surge protection.
