Coastal hazards are physical phenomena that expose a coastal area to the risk of property damage, loss of life, and environmental degradation.Rapid-onset hazards last a few minutes to several days and encompass significant cyclones accompanied by high-speed winds, waves, and surges or tsunamis created by submarine (undersea) earthquakes and landslides.
In a coastal example, erosion is a process that happens naturally on the Canterbury Bight as a part of the coastal geomorphology of the area and strong long shore currents. [3] [4] This process becomes a hazard when humans interact with that coastal environment by developing it and creating value in that area.
Coastal and estuarine ecosystems act as buffer zones against natural hazards and environmental disturbances, such as floods, cyclones, tidal surges and storms. The role they play is to "[absorb] a portion of the impact and thus [lessen] its effect on the land". [ 22 ]
The Coastal Zone Management Program was created by the Coastal Zone Management Act [2] (October 27, 1972). It provides grants to eligible states and territories as an incentive to prepare and implement plans guiding the use of coastal lands and resources. Thirty-four of the 35 eligible states and territories are implementing federally approved ...

Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. [3] On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion.
Aug. 2—The National Weather Service has extended its coastal hazard message for Hawaii to Thursday afternoon. Due to summer king tides, minor coastal flooding may occur in low-lying areas of the ...
