First there are body waves ,which are seismic waves that travel in the ground,originating from the focus,or the starting point of the earth quake above the body waves,just under the earth surface,travel  the slower moving surface waves.This is what shakes the ground violently and causes humans to feel the quakes intensity.When the quakes are over,aftershock occurs a tremor or a small quake following a large one finally there may be a landslide
