Has anyone conducted research on the existence of a connection between solar activity and seismic activity on Earth?

[Olga]

Are there any statistics?

 

[(Q)]

So, you can post in English. Are you pretending to feel solar activity again?

Я попала в зону землятрясения несколько часов назад. А за пару часов до этого моя голова начала сходить с ума, я на ногах не могла стоять из-за головокружения.

The Sun's Activity Can Trigger Earthquakes, And Now We Know How

On a dynamic planet like Earth, it can be easy for drivers of change to go unnoticed – but scientists have now established and investigated an unexpected link between the Sun and our homeworld.

I remain sceptical. I am reminded of those bogus statistical correlations : https://www.tylervigen.com/spurious-correlations

Mind you, I can see why margarine consumption might correlate with divorce

Thanks.

It is possible that sun/moon positions can produce some stresses.

The actions of the tides are actually slowing the revolution of the Earth about its axis ever so slightly, making days longer over millions and billions of years. At the same time, the Moon is pulled into a slightly higher orbit, or its distances from Earth increases by about 3cms a year. In a couple of billion years time, a day on Earth will be equal to a lunar month, the Earth will be in a fully captured tidally locked orbit, and will only ever have one side facing the Moon, just as the Moon at present only ever has one side facing Earth. We will probably never get to this stage anyway, as the Sun itself would be entering its giant red phase by then, and life will be extinct on a scorched Earth.

Yes. To put it in terms of mechanics, tidal drag between Earth and Moon results in a slow transfer of the Earth’s spin angular momentum to the Moon’s orbital angular momentum.

Я думала, что это может быть связано с тем, что в атмосферу перед землетрясениями выделяются радон и метан. Хотя, другие бы тоже так же реагировали бы на это, но такого не наблюдалось. Вот животные да, они были немного более активны, чем обычно.
