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.
Coastal erosion is one of the most significant hazards associated with the coast. Not in terms of a rare massive release of energy or material resulting in loss of life, as is associated with tsunami and cyclones, but in terms of a continual chronic release that forms a threat to infrastructure, capital assets and property.
Coastal flooding during Hurricane Lili in 2002 on Louisiana Highway 1 (United States). Coastal flooding occurs when dry and low-lying land is submerged by seawater. [1] The range of a coastal flooding is a result of the elevation of floodwater that penetrates the inland which is controlled by the topography of the coastal land exposed to flooding.

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 barrier islands and sandbars that make up the Outer Banks are highly fragile and are constantly changing their coastal landscape; some of the islands may only be 0.5 miles (0.80 km) wide and may recede back into the ocean over time. [3] Barrier island zones structure the islands of the Outer Banks from the ocean side to the sound.
The Columbia Bar is part of a set of major marine coastal hazards along the Pacific Northwest coast, including Cape Flattery at the northwest tip of the Olympic Peninsula and Cape Scott, which is at the north tip of Vancouver Island. Historically, the region's mariner's nickname was the Graveyard of the Pacific, and it is studded with thousands ...
