Answer 2

Explanation:

• When the earthquake happens the waves causes some vibrations that passes through the rocks.
• The propagation of these waves that are related with earthquake will not be similar in nature.
• P waves causes the pressure on the rocks in the same direction of its propagation.
• This will result in the creation of the differences in the density of the rocks.
• Other waves create pressure in the direction that is perpendicular to the propagation direction.
• The S waves will create pressure in the direction which will be perpendicular to the direction of propagation.
• This will result in the creation of crests and troughs in the rocks.
• The waves that are considered as a dangerous one will be L waves.
