Upon crossing the Moho from the crust to the mantle, P waves go faster in the mantle.


So when we monitor P waves traveling between different points in the crust, they can go directly through the crust or the longer length but faster speed across the Moho. Croatian scientist Andrija Mohorovicic first discovered that seismic waves can travel both routes, thus identifying the discontinuity that bears his name.
