The definition:
The earthquake is a phenomenon that results from a sudden

release of stored energy that radiates seismic waves.

It shows itself by a sharking of the ground. The earthquake causes extensive destruction of buildings.

Слайд 3

When does the earthquake occurs?
An earthquake occurs when earth releases energy

suddenly in the form seismic waves.

The tectonic plates in the earth’s crust which are almost hundred kilometers in thickness get dislocated because of seismic waves.

Слайд 4

Слайд 5

An earthquake is a natural phenomenon.
An earthquake is a natural

phenomenon.

But sometimes activities like oil drilling, coal mining, and construction of big dams also add up to the seismic activity.

Слайд 6

Earthquake intensity is measured with the help of seismometers. It is

also known as Richter scale.

The Richter scale.

The first seismograph, which had scientific value, was built in 1879 in Japan.

Слайд 7

Classification Depending on the cause and location of earthquakes are divided

into:

Tectonic

Volcanic

Слайд 8

The damage caused due to an earthquake depends on the location

of the epicenter of the earthquake

The damage

Major destruction occurs near the epicenter of the earthquake because maximum intensity locates at the center.

Слайд 9

Sometimes because of earthquakes there may be:
volcanic eruptions
and
landslides
