Earthquake types and types of Waves, its characteristics, incidences

Different Types of Earthquake

On the Basis of the depth of their Foci, there are three earthquake types, they are Deep-focus earthquakes, Intermediate focus earthquakes, and Shallow-focus earthquakes.
Deep-focus earthquakes: This type of earthquakes occur at depths exceeding 300kms.
Intermediate focus earthquakes: They occur with the depths of the focus ranging between 55Kms and 300Kms.
Shallow-Focus earthquakes: It occurs with the depth of focus, less than 55Kms.

Earthquake types of waves and Characteristics:

Earthquake waves

When Earthquake occurring time, there will be many vibrations spreads outwards in all direction from the focus point, it is known as Earthquake Waves.
These waves are classified into three types they are Primary waves, Secondary waves, and Long waves.

this waves commonly abbreviated as

P-waves: Primary waves

S-waves: Secondary Waves

L-waves: Long Waves

Characteristics of Earthquake waves:

The primary waves faster than secondary waves, like primary waves travels 1.7 times faster than secondary waves.
The Main cause of primary waves, it makes vibration of a rock particle to the backward and forward direction in the wave direction.
The P-waves are the first waves, gets recorded in the earthquake station, since its fastest waves among the other earthquake waves.
The Secondary waves cause the particles to oscillate at 90 degrees to the wave direction.
The primary and secondary waves converted into long Waves.
The Long waves either travel along surface horizontally at 90 degrees or travel sea waves.
Long waves are the very danger, great loss of destruction occurs due to long waves and it produces shocking violent waves.
The Primary waves can pass through any media.
The secondary waves cannot traverse the liquid.

Koyana earthquakes and the Latur earthquake in Maharashtra, 1967 and 1993 respectively.
Uttar Kashi earthquakes occurred in Uttar Pradesh in 1992.
The Bhuj earthquake occurred in Gujarat in 2001.
The earthquake occurred in Jammu and Kashmir in 2005.
