Earthquake reason
Earthquake is not the punishment of anyone's sin. Those who say these things are quite ridiculous. Completely coincidentally, when a natural disaster occurs during a significant incident in the opposite party of their ideology, they claim that it is the punishment of their conduct or the punishment of their behavior. When, again, completely coincidentally, why do not they take it on their necks when there is a natural disaster in their significant festivals? Still others insisted on saying - "Bad day has come bad, it's a fancy! Now it's just a hindrance to do good things. "To all of them, I want to say, the main reason for the earthquake is only to be heard by two words - Plate Tektonics. To make it easy to understand, the USGS's underprivileged section is taking help. I mean, they mean kids with it. You will also understand, hope.
The cross section of the globe is found in four sections. Crust on top of all, Upper Mantle below, Lower Mantle below, and then center (Core).
Earth's stratification
Though this upper case looks seemingly stable, it is not the case but it is not. They are all together in the world, but they are now segregated by the sea. At one point Raidenia said that, almost 1 billion years ago. It was broken 600 million years ago. After that it was reunited, we call it Panzia It also started to be separated and 175 million years ago. Simply put, the upper skin was never really quiet. They are strolling on different plates, separated by plates.
Plates are very close in many places. You see the boundaries of two plates so close, and you feel that there is a fault here. When these two plates friction with each other. Since the plate boundary is uneven or elevated in comparison to another place, it is stuck. But the rest of the plate but still running. It's still happening (when you do not feel anything, still), the soil shakes. In the end, when the plate has moved a bit further, and the boundary also knocked down, then there was a lot of shaking. And that's what you said earthquake
Sit down at home and do a little research yourself ...
Do the boxes that the TVs, laptops do, do not have rubber foam? Take a rubber foam.
Break from the middle.
Put two parts on a table after that, put the pieces in the same position as before breaking them.
In this way ...
In this way ...
Then push one part, then drag another part.
Fault line is breaking some foam rubber in the middle friction, so?
This is the earthquake.
Magnitude / intensity of earthquake
A common misconception is that "as far as the origin of the earthquake, the degree of earthquake will be reduced." But that is not really true. The earthquake of 2016 on 13th of 2016 was Myanmar. The level of this is called 6.9. So what has it reduced to reaching Bangladesh or reaching Calcutta? Yes not The magnitude of the earthquake is the same, and it is judged by the origin. Many times before I used to say, when we measure the temperature of the sun, we measure the temperature of the sun's surface or measure the temperature of the center. It does not calculate the temperature of the sun, but it takes hold of the heat that comes in the world.
So why is the loss of the origin of the cause? Why are the losses less away from the origin? Something must be reduced! Yes, it decreases, and that is the intensity of earthquake. The intensity at this center is highest and the distance from the center / source is less as the intensity of the earthquake. The April 2012 earthquake was in Nepal, where there was high intensity, the loss was more. The intensity of Bangladesh was low, the loss was less. It is not measured by the knower of all of us. There is another scale, it's time to talk about it.
Richter Scale
In 1935, Charles Richter and Beno Guttenberg, both of whom were tried by the Caltech earthquake, tried to determine the real magnitude of the earthquake. Seismographs (which are found in graphs or graphs of the earth's vibrations) - The rugger level is determined by the logging of the waveform. In other words, what exactly is shaking at the exact point of our Sasogram, that's what! The 4 magnitude earthquake of the Richter scale trembles 10 times more than 3 degrees, similarly the 5-magnitude earthquake shakes 10 times more than the 4-magnitude earthquake. This scale is now called the local magnitude scale.
Now, notice that Caltech University is in California. This scale was designed for the earthquake of 16 kilometers of soil, like California. But earthquake of all the world has been verified, it can be up to 0 to 700 kilometers below. Modern era machinery can accurately calculate the vibration of any place on Earth, so it was necessary to rebuild the original Richter scale.
Richter is actually Moment Magnichidae
Moment magnitude scale, was built in the late 1970s, many scientists of Caltech. It can calculate the effects of earthquake better. This scale uses both the vibrations of the vibrations and the power, and determines the total energy of the earthquake. Fault geometry is determined by the different shape and direction of the wave at different distances. From the standards of this wave, the earthquake is defined as the earthquake.
