the point from where seismic waves release is known as. a) focus b) hypocentre c)both d) none of above​

Answer 1

Answer:

Following an earthquake event, S-waves arrive at seismograph stations after the faster-moving P-waves and displace the ground perpendicular to the direction of propagation. ... Shear waves can't travel through any liquid medium, so the absence of S-wave in earth's outer core suggests a liquid state.
