Q. Consider the following statements regarding earthquakes:
1.The focus of an earthquake lies within the Earth, while the epicentre is the point on the surface directly above it.
2.The intensity of an earthquake is always highest at the epicentre and decreases uniformly with increasing distance from it.
Which of the statements given above are correct?
Answer: A
Notes:
Explanation:
- Statement 1 is correct: The focus (hypocentre) is the point inside the Earth where an earthquake originates. The epicentre is the point on the Earth’s surface directly above the focus.
- Statement 2 is incorrect: Earthquake intensity does not necessarily decrease uniformly with distance from the epicentre. It is influenced by factors such as depth, local geology, soil conditions and building structures.
