Earthquake is one of the natural disasters on earth. it is caused due to the seismic activity on the asthenosphere. The earth has multiple layers. The upper layer contains a flexible and moving layer, which during subduction goes inside the upper and inner core of the earth. Most of the dangerous earthquakes are produced in the ring of fire in the pacific and Indian ocean. In 2005, Pakistan witnessed a terrible earthquake in northern areas.
What is the earthquake?
The surface of the Earth remains in continuous slow motion throughout the time. The sudden release of tension in the tectonic plates sends waves of energy that travel through the Earth and then shaking that radiates out from the breaking rock is caused by the earthquake. Earthquakes effects in two ways: one is primary and the second is secondary. The primary effects of the earthquake are ground shaking, ground rupture, landslides, tsunamis, and liquefaction while the secondary effects of earthquakes are Fires probably the single most important effect.
When earthquakes occur more frequently?
Where does an earthquake come from?
Mostly earthquakes come from these three tectonic plates: the continental North America plate with two oceanic plates, the Juan de Fuca and the Gorda plates.
Who is affected by earthquakes?
Humans, animals, birds, and plants are severely affected by earthquakes. Earthquakes can result in loss of life, trauma, and in some cases injuries. Hence, it is best to immediately shift to safe locations at the time of the earthquake.
Why earthquakes occur?
It is caused by tectonic movements in the Earth's crust when tectonic plates ride one over the other, causing progeny, and severe earthquakes.
How an earthquake is caused?
Earthquakes are usually caused when the sudden release of energy causes the seismic waves that make the ground shake and then rock underground suddenly breaks along a fault.
