How earthquake happen??

So How Do Earthquake Occur Underneath the Earth Surface??

Well, this is what happen exactly :-

~The Earth is divided into a solid core, then molten magma mantle and the crust floating on top~






~The crust is broken up into plates. Convection currents in the magma cause the plates to move in different directions~


~Most Earthquakes occur at the plate boundaries~



~Where plates converges, one plate is drawn slowly beneath the other. This takes place over thousands of years~

~Where plates collide, rock layers are forced upwards creating mountains~


~Where plates diverge, lava emerges from the mantle and cools to form new sections of crust. Diverging plate boundaries are often found underwater~


~Other plates move very slowly alongside each other. Faults or also called as Fractures are found at the edges of the plates where the crust is moving in different directions ~


~In some places the plates become locked together. Kinetic energy builds up in the locked plates~

~When the plates give, the stored energy is released in the form of an earthquake. The point of earthquake's origin beneath the surface is called the hypocentre~



~An earthquake emits its power as three waves of energy. Primary or P-waves are felt as a sudden jolt. Secondary or S-waves waves arrive a few seconds later and are felt as a more sustained side-to-side shaking~

~Surface waves radiate outwards from the epicentre - the point on the surface directly above the hypocentre - and arrive after the main P and S waves~



The main thing is how to save your life and your loves one. Here are a few tips on how to keep you and your beloved ones safely. It might be useful for those who never experienced or are from a free earthquake country.

1) Pick safe places in each room of your home and your office or school.

2) move as little as possible to reach the place that you feel safe. Most injuries happen when people try to move more than a few feet during the shaking.

3) Hang items such as pictures and mirrors away from beds, couches or places that people sit or sleep. Earthquake might caused the wall to fall on you and you might be injured.

4) If you are in a coastal area, Drop, Cover and Holds On during an earthquake and then move immediately to higher ground when the shaking stops.

5) Drop to the ground and stay there until the shaking stops.
