Easy questions lol.

1st one, no-one really knows.

But from my (outdated) solar storm thread:

-------Solar Storms and Earthquakes-------

Some have theorized that the magnetic fluctuations of geomagnetic storms can have an influence of the frequency and magnitude of earthquakes by causing minor magnetic/physical vibrations to go deep underground, all the way to the producer of the magnetic field.

The worry is that the geomagnetic storms can set off large earthquakes.

Now you may find other theories elsewhere, but here is mine.

Now if it can set off earthquakes, A basic assumption would be that due to it be tiny fluctuations/vibrations etc, that they will only set off an earthquake just before its time.

The way I see it this will actually lower the magnitude of the earthquakes, due to them having less time to build up energy.

This also assumes that the frequency of earthquakes will only have a minor rise when a solar max is in effect in comparison to a solar min, since the time that the earthquake could be set off may only be a day, a week, a month. Hardly anything in the long run.

But with my assumptions, I come to the conclusion that the highest magnitude earthquakes are more likely to appear on a deep solar minimum, as they have the peace and quiet and constant stability to grow and grow in energy ready to be released.

Yes there is more to the theory but I don't want to clog up the guide too much, the basic point of my theory is that although we may experience a slight rise in the frequency of earthquakes (mainly small) that we should be grateful that they were set off before they had time to grow even bigger, and hence solar max's and general solar storms actually keep the magnitude and overall damage from earthquakes down.

Beyond that there's no real data to suggest one way or the other.

2nd question, Liekly will compress the heliosphere, and the effects will solely rely on how much it becomes compressed, logically we shouldn't notice anything different unless the heliosheath gets close to us, where the interplanetary magnetic field density will increase and geomagnetic storms will be very intense.

And with a lot of compression, I mean a lot, one would assume that the poles of the sun will expand, think of them like magnetic dipoles here on earth, where under a lot of stress, the aururos drop down in latitude.

Then one would assume the sunspot and active region intensity on the sun will increase.

But since it hasn't happened in living memory, we just don't know.
