Tsunamis and storm surges
Tsunamis and storm surges are caused by different events but both result in flooding and damage to coastal areas. Tsunamis are immense sea waves (10 metres or more), which are produced by underwater events such as earthquakes, mudslides and volcanic eruptions. They start out small in the open seas but amplify in size as they reach shallow water. In 1929, when an earthquake-generated tsunami hit the south coast of Newfoundland, 28 people died.
Storm surges are elevated sea levels produced by intense marine low pressure systems. Storm surges at times of high tides can lead to coastal flooding and are often accompanied by large ocean waves.
For further information on specific events, see the Canadian Disaster Database.
