And this is what I meant about argument... See Post 15221 for just one example of how there are things besides solar flares that may trigger quakes:

GEOMAGNETIC/SOLAR FIELDS

Delayed effects from the recent strong geomagnetic storms were
probably important in the timing of the Balkans and the Andreanoff
Islands earthquakes today. Strong events often follow X-class solar
flares 3-5 days later in sub- and anti-solar regions.
The geomagnetic field, however was at quiet conditions today. The
proton storm was reaching background proton flux. As this occurs,
electrons are more able to form ring currents and associated earthquake
triggering often occurs in higher latitudes and along the geomagnetic
equator in addition to the areas already under seismic watch conditions
from the storms and flares.
One M-class solar flare was recorded today with the following parameters:
