Scientists
said several factors, including:
1. Volcanic eruption, which was
accompanied by an earthquake.
2. Fault rocks and sliding it which
is known tectonic earthquakes.
There is a range of factors lie behind the
revolution of earthquakes on the Earth's surface, where it can be divided into
internal factors associated with the land and the composition which is composed
of several layers are from the outside inwards: 1 crust 2. Mantle 3. The core
of the Earth
And consists of "the core of the
earth" of a solid ball of iron and ***** s is characterized by a degree of
up to several thousand degrees Celsius, "about 6,000 degrees Celsius"
and the fact that layers of the earth is a homogeneous process occurs for the
transmission of heat from one region to another,
both feature in the
conductivity of solid or pregnancy in the liquid or feature of radiation on the
surface of the earth, and when the accumulated power locked in an area in the
layers of the Earth showing the role of the sun and the moon through the waves
of attraction that it influences the Earth, which allows editing the heat
stored within the earth in the form of earthquakes and volcanoes.Coupling
phenomenon also stands behind the planets, earthquakes, volcanoes, where the
tidal forces of the solar and lunar, the largest possible, which helps to edit
the heat the earth explains the short duration of the small planetary pairing
long haunt the land seismic
Location and geology also play an important
role in the occurrence of earthquakes, affects the thickness of the earth's
crust, with its faults and cracks and being islands in the ocean or the land of
rock. Add to that the more the planet was close to the sun increased
gravitational influence and caused an earthquake and volcanoes, huge as it is
happening on the planet Venus, and the larger planets and lags from the sun
under the earthquakes and volcanoes, which receives the ground its heat from
two sources first is the sun, which shows the impact on surface area the upper
part of the cortex, which no more than 28-30 m and is the second source of
geothermal resources, which result largely from the radioactivity of some
elements, especially uranium and thorium and other highly radioactive elements
