Volcanic eruptions are not typically considered coastal hazards, as they are not directly related to the coastal environment.

Coastal erosion is caused by a combination of factors, including sea level rise, wave action, and human activities such as shoreline development and sand mining.

Storm surge is a sudden and rapid rise in sea level caused by the force of a storm, typically a hurricane or tropical cyclone.

A tsunami is a large, destructive wave generated by an underwater earthquake or landslide.

An earthquake is a sudden release of energy in the Earth's crust beneath the ocean floor.

Hurricane, tornado, and cyclone are all terms used to describe a strong, rotating wind system that forms over warm ocean waters.

Allowing natural processes to occur is not typically considered a strategy for mitigating coastal erosion, as it can lead to further erosion and damage.

A rip current is a strong, narrow current of water that flows away from the shore.

Sea level rise is a gradual rise in sea level over an extended period of time.

A megatsunami is a large, destructive wave generated by a landslide or rockfall into a body of water.

A volcanic eruption is a sudden and violent release of energy in the Earth's crust beneath the ocean floor.

A tsunami is a series of large waves generated by a disturbance in the ocean, such as an earthquake or landslide.

Sea level fall is a sudden and rapid drop in sea level.

A hurricane is a strong, rotating wind system that forms over warm ocean waters in the Atlantic Ocean.

Storm surge is a gradual rise in sea level over a short period of time, typically caused by a storm.
