The Relevance of Earthquakes Above 7.0 to Earth’s Rotation Speed

“Can a solar eclipse trigger earthquakes?” let there be talk of such claims, the earthquakes one of the main triggers A comprehensive study was conducted in 2017 on what one could be.

According to this study, published in the journal Geophysical Research Letters, Minor changes in the Earth’s rotation speed It can even affect the frequency of major earthquakes.

When examining the number and dates of earthquakes of 7.0 and above between 1900 and 2017, something interesting was noticed:

These earthquakes are strangely At times it was concentrated and at other times it was sparse. In addition, the number of large earthquakes was reaching its highest point in 32-year time intervals.

So why did such an effect occur?

No, not Mercury retrograde! The real culprit was Earth itself. Although we think that the Earth rotates around itself in 24 hours, this is The rotation speed is actually not constant.

the length of a day microsecond differences This is because of changes in the mass distribution of our planet. What causes this are factors such as changes in the direction and strength of the winds, the movement of the plates in the earth’s crust, the movement of the Earth’s liquid outer core.

Let’s give an example of an ice skater in order to better understand why the rotation speed of the Big Earth is affected by these:

Just as an ice skating athlete pulls his arms around himself to increase his speed and opens his arms to decrease his speed, the differentiation of the rotation speed of the Earth is similar to this. This conservation of angular momentum in physics we say.

However, it is impossible to know the exact date of major earthquakes!

of the world when the rotation speed increases The number of major earthquakes is also increasing. The time period in which earthquakes will increase is known, but it is quite difficult to make a pinpoint forecast. Even this millisecond difference can cause a butterfly effect and affect thousands of people.
