ii.1. Earthquakes: Nature’s Powerful Forces

Earthquakes are natural phenomena characterized by the sudden release of energy in the Earth’s crust, leading to seismic waves. While earthquakes are essential in shaping the Earth’s landscape, they can also pose significant threats to human communities, emphasizing the importance of preparedness and resilient infrastructure.

Understanding Earthquakes: Tremors, Origins, and Impacts

  • Meaning: A sudden shake or trembling of the earth which lasts for a very short time is referred to as an earthquake.
  • Focus: The point inside the earth where the earthquake starts is the focus point.
  • Epicenter: It is the point on the surface of the earth above the focus point.
  • They may also cause floods, landslides, tsunamis, and loss of life.

Causes of Earthquakes: Deep Disturbances, Plate Dynamics, and Varied Triggers

  • Deep Disturbances: It is caused by a disturbance deep inside the earth’s crust.
    • The outer layer of the earth is fragmented.
  • Plate: Each fragment is called a plate. 
  • Continuation Motion: These plates are in continual motion, so when they brush past one another, or a plate goes under another due to collision, they cause disturbance in the earth’s crust.
      • It is this disturbance that shows up as an earthquake on the surface of the earth.
  • Different Causes: The other causes are volcanic eruptions, meteor hits, and nuclear explosions.
