And the big question, is this going to destabilize ALL the plates, worldwide?
Just finished reading an opinion by an astrophysicist that the massive Coronal Mass Ejection (CME) from the sun a couple weeks ago may well have been the trigger.
Some also say that in years of solar minimums (few sunspots) there is more seismic and volcanic activity due to decrease of electromagnetic and geomagnetic waves that help stabilize the Earth.
