It has been suggested, and in fact there is some supporting evidence,
that there is a connection between solar and sceismic activity. In
other words, powerful solar events such as strong flares can trigger
earthquakes. The presumed mechanism is that the fluctuations induced
into earth's magnetic field end up creating stress deep within the
earth, and that if a fault were on the verge of slipping, that extra
stress might be enough to trigger it. The 9.0 earthquake of 12/26 had
no matching solar event. My thoughts and prayers go out to all of
those who have been hurt by this tragedy.
Solar activity is beginning to pick up a bit, although no significant
flares have been generated as of yet. Sunspot region 713, which is
nearing the western limb of the solar disk, experienced an increase in
both size and magnetic complexity, and produced a C7 class flare.
Just now coming into view is region 715, which also produced a C7
flare today. That sunspot might be worth watching in the days ahead.
The earth is now moving out of one coronal hole solar wind stream and
moving into another. While no geomagnetic storms are predicted at the
present time, I wouldn't be surprised to see the K index touch the G-1
geomagnetic storm for a brief period over the next few days.
