Consider the following statements regarding earthquake waves :
(1) All earthquakes take place in Asthenosphere
(2) Body waves are faster than surface waves and arrive first at the surface, hence they are more damaging than surface waves
(3) S-Wave propagation reveals that the outer core of the earth is in liquid form
(4) P-Wave propagate longitudinally, while S-Wave transversely.
Which of the above statements is/are incorrect?

Incorrect Statements Regarding Earthquake Waves
Statement 1: All earthquakes take place in Asthenosphere
This statement is incorrect. Earthquakes can occur in any layer of the earth's crust, including the lithosphere, asthenosphere, and mesosphere.
Statement 2: Body waves are faster than surface waves and arrive first at the surface, hence they are more damaging than surface waves
This statement is partially correct. Body waves (P-waves and S-waves) are faster than surface waves (Rayleigh waves and Love waves) and arrive first at the surface. However, surface waves cause more damage as they have larger amplitudes and longer wavelengths.
Statement 3: S-Wave propagation reveals that the outer core of the earth is in liquid form
This statement is correct. S-waves cannot pass through liquids, and hence their absence in certain regions of the earth's interior suggests that those regions are in liquid form. The outer core of the earth is believed to be in a liquid state.
Statement 4: P-Wave propagate longitudinally, while S-Wave transversely.
This statement is correct. P-waves are longitudinal waves, which means that the particles of the medium vibrate parallel to the direction of wave propagation. S-waves are transverse waves, which means that the particles of the medium vibrate perpendicular to the direction of wave propagation.
Conclusion
Therefore, the correct option is (c) 1, 2, and 4 only, as statement 1 is incorrect while statements 2, 3, and 4 are partially or completely correct.
