They go faster through the inner core than the liquid outer core
body waves
When S waves, or secondary waves, encounter the Earth's inner core, they are unable to penetrate it because S waves are shear waves that require a solid medium to travel through. Since the inner core is solid and composed primarily of iron and nickel, S waves are reflected and do not pass through. This phenomenon contributes to the understanding of the Earth's internal structure, as it indicates the transition from the liquid outer core to the solid inner core.
Seismic waves pass through the solid inner core, but they experience a decrease in velocity and may refract due to differences in density and composition from the surrounding layers. The waves can also encounter reflection and scattering as they interact with the boundaries of the inner core.
Earth's solid inner core influences seismic waves by acting as a boundary that alters their speed and path. P-waves (primary waves) can travel through both solid and liquid, allowing them to pass through the inner core, while S-waves (secondary waves), which can only move through solids, are reflected at the boundary between the liquid outer core and the solid inner core. This interaction creates distinct shadow zones where S-waves are absent, providing crucial information about the Earth's internal structure. Additionally, the properties of the inner core can lead to variations in wave velocity, aiding scientists in understanding the Earth's composition and dynamics.

S waves (secondary waves) cannot pass through Earth's inner core because it is liquid. S waves travel by shearing the rock, which is not possible in a liquid medium. Only P waves (primary waves) can pass through the inner core because they can travel through both solid and liquid material.

earthquake waves travel through the earths crust.
While S waves (shear waves) can travel through earth's solid inner core, they cannot travel through earth's liquid outer core, which surrounds the inner core.So, unless the S waves originated inside the inner core (which seems unlikely) there are no S waves traveling through earth's inner core.

Primary (P) waves can pass through the solid inner core of the Earth. P-waves are the fastest seismic waves and can travel through solid, liquid, and gaseous materials.
S-waves are not transmitted through the outer core.
