Interesting thread, but it seems there are a few misconceptions involved.
First, let's look at the scale on the earth to the sun.
The earth and the sun are no where close to the same size, which is something people tend to forget when talking about solar activity.
Here's another pic that shows all the planet's relative size.
And a bit about distances.
Secondly, what appears as a hole, a cooler region, is because the corona of the sun IS hotter than the surface of the sun. What you think is a hole
is more accurately a glimpse at the surface of the sun, beneath the corona, basically a temporary lapse in the corona above that section of the sun.
The sun is not really cooling down, when you see pictures as listed, merely expressing it's dynamic and constantly changing behaviour.
The Sun’s Core is at a temperature of approximately 13.6 million Kelvin (~25 million degrees Farenheit). The optical surface of the sun (the
photosphere) is known to have a temperature of approximately 6,000 K ( 10340 degrees Farenheit, 5700°C). Above it lies the solar corona, rising to a
temperature of 1,000,000–2,000,000 K. Herein lies the problem: how can the corona of the sun be millions of kelvin hotter than the lower
surface of the sun (photosphere)? The second law of thermodynamics can be stated in the form attributed to Rudolf Clausius: “Heat generally
cannot flow spontaneously from a material at lower temperature to a material at higher temperature.” In other words, heat would normally be unable
to flow from the solar photosphere to the hotter corona, so we must conclude that something other than direct heat conduction must be responsible for
the high temperatures in the corona.
The most interesting part is in the fact that the corona is hotter than the surface of the sun, and a question that physics can't explain yet.
Thirdly, solar activity is in no way related to earthquakes.
Earthquakes happen all the time, and happen because of plate tectonics, and the earth's molten core. Here's a nifty
link to watch REALTIME seismic activity.
As you can see, earthquakes are based upon fault lines, tectonic plates rubbing against one another, and most of the solar influence is filtered by
our own magnetosphere anyway.
