Seismic Waves and the Shadow Zone: a 3D model for Class 11 Social Science, covering An earthquake starts at the focus inside the crust; the point on the surface straight above it is the epicentre., Body waves travel through the Earth: P waves (primary) are faster and arrive first, S waves (secondary) arrive later., P waves push and pull and pass through solids, liquids and gases; S waves shake sideways and pass only through solids., The outer core is liquid, so S waves cannot cross it: no S wave is recorded beyond 105° from the epicentre., P waves bend as they enter the core, so none arrive between 105° and 145°: the P-wave shadow zone..
