Natural disasters

In the English class we have learnt that most natural disasters are caused by weather. Weather disasters can be caused by wind storms, hurricanes, tornadoes, floods, tsunamis, wildfires, thunderstorms, avalanches, and blizzards.
Did you know that the name "volcano" has its origin from the name of Vulcan, a god of fire in Roman mythology?

And did you know that the name "tsunami" is Japanese? It means harbor wave!
