<P> Coastal Hazards are physical phenomena that expose a coastal area to risk of property damage , loss of life and environmental degradation . Rapid - onset hazards last over periods of minutes to several days and examples include major cyclones accompanied by high winds , waves and surges or tsunamis created by submarine earthquakes and landslides . Slow - onset hazards develop incrementally over longer time periods and examples include erosion and gradual inundation . </P>
