Hello all,

I am going to settle this. Solar activity does not increase earthquake,
as the gravity of the sun does increase or decrease during solar minimun
and solar max.=20

There are not even a good evidence that the moon creates earthquakes on
the Earth. But the Earth creates moonquakes on the moon.

The claim if this nature that the sun increases the risk of earthquakes
are unfounded and not based on anything credible far as I can tell.

About the Moon,
