What major natural disaster was there in Italy in 1908?

1. earthquake
2. volcanic eruption
3. tsunami
4. landslide

Build-up of the tsunami

• Wave comes to the coast at high speed
  
• Shallow water slows down the wave
  
• As a result, the water piles up into a high wall of water
  
• With great force, the water floods the land
  

The consequences for inhabitants

• Many (fatal) victims
  
• High economic damage (€)
  
• Radioactive radiation from explosion of nuclear reactor (in Japan)
  
• Nature destroyed 

A tsunami is a ....

1. Disaster caused by humans
2. a natural disaster

What is a tsunami?

1. a wave
2. High tidal wave at sea that floods the coast and is caused by a seaquake.
3. An underwater earthquake
4. A high tidal wave caused by very strong winds at sea.
