I have compiled a list showing the 30 most powerful earth directed solar flares recorded since 1976.
I then went through these dates to find out if any earthquakes occurred after these significant solar flares, a typical flare will reach earth within
2-3 days, with the largest known (1859) reaching earth in 18 hours, so my criteria was two days after the flare and the following two days after that
to find my data.
Here are the results:

5.5 Northeast China Mar 25

14 24/05/90 X 9.3 Nothing of significance
15 05/12/06 X 9.0 Nothing of significance
15 06/11/80 X 9.0 Nothing of significance
15 02/11/92 X 9.0 Nothing of significance
Only 8 out of the 30 fitted the criteria (
28%).
To add to this further the largest magnitude earthquake from this list was a
7.4.
On average (since 1900) we will get a 7.0 - 7.9 magnitude earthquake 15 times a year.
So, despite the various theories connecting solar flares and earthquakes being thrown about, the cold hard facts and numbers makes me think it's all a
load of doo doo
Less than 30% is way too low for any correlation IMHO
