# When a major earthquake occurs, there is a ring around Earth's surface between 102^o and 143^o from the epicenter where P-waves are absent Why are P-waves waves not detected in this area? (1) P-waves are bent and reflected away from this region. (2) P-waves can pass through a solid, but not a liquid. (3) This zone is too far from the epicenter to record seismic waves. (4) Seismic waves cannot travel through Earth's interior.

Out of all the given options, the correct explanation of P-waves being absent in this ring-shaped shadow zone is given by option (1). P waves get reflected and refracted in this region.
Result:
(1) P-waves are bent and reflected away from this region.
