Question

Which of the following is/are likely to be caused by an earthquake?

• A. Liquefaction
• B. Heatwave
• C. Tsunami
• D. Tornado

Hint:

Earthquakes can have significant secondary impacts, such as liquefaction and tsunamis, especially in coastal and water-saturated areas.

Answer 1

The Correct Option is A, C

Step 1: Earthquakes can cause several secondary natural disasters, including liquefaction and tsunami.
Step 2: Liquefaction occurs when the ground, typically composed of loose, water-saturated sediments, temporarily behaves like a liquid due to seismic shaking. This can cause buildings to sink or tilt.
Step 3: Tsunamis are large ocean waves that are often triggered by underwater earthquakes. These waves can cause extensive flooding in coastal areas.
Step 4: Heatwaves and tornadoes are not typically caused by earthquakes. They are separate natural phenomena with different causes.
Conclusion: Liquefaction and tsunami are secondary effects caused by earthquakes.
