Consider the following statements about earthquakes:
Consider the following statements about earthquakes:
- AOnly 1
- BOnly 2
- CBoth 1 and 2
- DNeither 1 nor 2
Answer and explanation
Correct answer: A
The maximum damage from an earthquake occurs at the epicentre, the point directly above the focus, so statement 1 is correct. Statement 2 is wrong because near the epicentre the seismic waves reach the surface almost at right angles, nearly vertically, rather than obliquely as a 'to-and-fro movement'. Only statement 1 is correct.
