“Can a Solar Eclipse Cause Earthquakes?” let there be such claims, the earthquakes one of the main triggers In 2017, an extensive study was conducted into what one could be.

According to this study, published in the journal Geophysical Research Letters, Small changes in the Earth’s rotational 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, we noticed something interesting:

These earthquakes are strange Sometimes it was concentrated and sometimes it was sparse. In addition, the number of major earthquakes reached the highest point in time intervals of 32 years.

So why did such an effect occur?

No, not Mercury retrograde! The real culprit was the Earth itself. Although we think that the Earth revolves around itself in 24 hours, it does The rotational speed is actually not constant.

the length of a day microsecond differences This is due to changes in the mass distribution of our planet. What causes this are factors such as changes in the direction and strength of the wind, 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 a skater to better understand why the rotational speed of the Great Earth is affected by this:

Just as a skater wraps his arms around himself to increase his speed and opens his arms to decrease his speed, the differentiation of the Earth’s rotational speed is similar. This one 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 rotational 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 an accurate prediction. Even this millisecond difference can cause a butterfly effect and affect thousands of people.
