Effects of Tsunamis, Hurricanes and Cyclones

1.What Is a Tornado?

• A tornado is a deadly and destructive rotating cyclonic storm that originates from the base of a thunderstorm.
• The speed limit of a tornado could be 300 miles per hour.
• Tornados are a common disaster in Australia, South America, Asia and Africa.

2.What Is a Tropical Depression?

• A tropical depression is the first stage of a tropical weather event.
• They are cyclones characterised by winds with a speed of 38 miles per hour.
• They can lead to heavy rainfall, floods and thunderstorms.

3.What Is the 'Saffir-Simpson Hurricane Scale'?

• The Saffir–Simpson Hurricane Scale is a sorting scale used to check the magnitude of intense tropical storms in the Western Hemisphere.
• This scale is used for stronger storms than 'tropical storms' that become actual hurricanes.
• This scale has several categories according to which hurricanes are separated as per the strength of their maximum wind speeds.

4.What causes a Tsunami? Can a volcano eruption lead to a tsunami?

• An earthquake near or on the ocean floor leads to significant and sudden water displacement, resulting in a tsunami.
• Volcanic eruptions produce waves which may displace large amounts of water in water bodies leading to a Tsunami.
