I ain't a seismologist, but...

...yesterday there was a geomagnetic storm relating to solar activity that registered 9 on the K-Index, that got measured by the National Oceanic and Atmospheric Administration. According to the link on NOAA's website the affects of this kind of storm...

...include widespread power system voltage control problems; some grid systems may experience complete collapse or blackouts. Transformers may experience damage. Spacecraft operations may experience extensive surface charging; problems with orientation; uplink/downlink and tracking satellites. Satellite navigation may be degraded for days, and low-frequency radio navigation can be out for hours.

I've noticed during the past couple of years that whenever Earth gets hit with a massive dose of these particles from the sun, that we start having a lot more active earthquake activity. It happened this past December before the quake and tsunami in southeast Asia, and its happened a few other times lately. Maybe the nickle/iron mantle and core of the Earth get agitated or something and they rattle the upper plates. Dunno for sure but I'm gonna keep an ear open in case anything seismic happens during this next week or so.
