Natural Disasters

Our ocean planet is dynamic and constantly changing, sometimes resulting in dramatic threats to humans.


An earthquake is a shaking of the ground that occurs when two large blocks of Earth's crust slip suddenly past one another.


Hurricanes are large rotating tropical storms with winds in excess of 119 kilometers per hour. They usually form in the Atlantic Ocean but can develop in other oceans as well.


A tsunami is a massive, fast-moving wave created by an underwater earthquake or landslide. Displaced ocean water creates waves with speeds of up to 500 miles per hour.
