Earthquakes

Earthquakes are the result of plate tectonics or plate movement in the crust, earthquakes occur when friction stress is established at the boundary of the skateboard and the fault line breaks. In an earthquake, elastic strain is released, waves are radiated, and vibration may occur on the ground. Scientists can predict where a large earthquake will generally occur, but research can not predict or accurately predict a specific location. A major earthquake, some of which caused the tsunami, destroyed the entire city and affected the whole country. Relatively small earthquakes can also be caused or caused by human activities such as extraction of minerals from the earth and collapse of large buildings.

I chose to study earthquakes and predict earthquakes. In this article I will explain the history of the earthquake, the type and location of the earthquake, the impact of the earthquake, the scale of the intensity, the forecast, and my own forecast. An earthquake can be defined as vibration occurring in the Earth's crust. There is friction between the structural plates. This is the case when friction occurred when pushed and opened, suddenly damaged and then bounced back. - Purpose of earthquake: Define and discuss earthquakes and their effects. Earthquakes are major disasters that can pose a major threat to human lives. In order to understand the earthquake it is necessary to have a clear definition, know the mechanism, identify the size and dynamics, and understand its influence. I.

Earthquake measurements use seismographs to measure the force of an earthquake. Detect vibration caused by the earthquake and display it on the seismograph. The magnitude 6 earthquake is ten times stronger than the magnitude 5 earthquake, which means the intensity is greater than level 4. At this level, you can directly compare the strength of the earthquake (intensity), but you can not relate earthquake strength to damage. In order to overcome this, the Mercari scale measures these effects. It has 12 ticks to see different strength (but uses Roman numerals I - XII)

The amplitude scale is logarithmic. This simply means adding one to the magnitude of the earthquake multiplies the magnitude of the magnitude of magnitude 10 by the magnitude. The magnitude of the earthquake is 10, the magnitude of the earthquake of magnitude 6 is 10 times the magnitude of the magnitude 5 earthquake. wait. The only way to compare earthquakes is not vibration. Another common way is to speak about the relative energy they release. To do this, insert a simple extra step. Subtract the size, add 50% then add the result as a power of 10. In mathematics, the expression is 10 ^ ((M1 - M2) * 1.5).
