☆ANSWER☆
Earthquake produces three types of seismic waves :-
● Primary Waves
● Secondary waves
● Surface Waves
Surface waves are the most destructive because they cause damage to the upper crust where most of the population and people live.
In case of origin of earthquake from the epicentre, we can follow the following measures : -
●If you are in a vehicle, pull over and stop. Set your parking brake.
○If you are in bed, turn face down and cover your head and neck with a pillow.
●If you are outdoors, stay outdoors away from buildings.
○Do not get in a doorway.
●Do not run outside.

Answer:
Although surface waves travel more slowly than S-waves, they can be much larger in amplitude and can be the most destructive type of seismic wave. There are two basic kinds of surface waves: Rayleigh waves, also called ground roll, travel as ripples similar to those on the surface of water.
