Sorry, there is no connection. Do earthquakes stop during solar minimum when the coronal holes are at the sun's poles? There's an observed decrease of geomagnetic effects of CHs during minimum, so we should easily see a big dropoff in earthquake activity (if they correlated, which they don't).

"“Usually, at solar minimum, the coronal holes are at the sun’s poles,” says Giuliana de Toma, a solar scientist at the National Center for Atmospheric Research whose research on this topic helped provide insight for this paper. “Therefore, Earth receives wind from only the edges of these holes, and it’s not very fast. But in 2007 and 2008, the coronal holes were not confined to the poles as normal.”
Coincidental evidence? Not hardly. In 2008 the coronal holes remained at low solar latitudes with their winds pointed directly toward Earth. Not until 2009 did they move toward the Sun’s poles and geomagnetic effects and sightings of the aurora went proportionally along with it. It’s even been theorized coronal holes may be responsible for minimizing the southward direction of the interplanetary magnetic field as well. Such a combination of all factors are setting the stage for geomagnetic minimum, but study is still needed to help understand and predict such phenomena."
