Welcome to the dynamic Earth. Watch with love.
Many such events happen for reasons that are combination's of uncountable qualities and conditions of crust and deep crust events. This was a
itsy-bitsy event of surface geologic dynamics.
Earth's geology is 95% a mystery. The core, the strata of the planet are only partially even 'guessed' at.
As of 2008, the deepest mine in the world is TauTona in Carletonville, South Africa at only 3.9 kilometers. That is depth relative to the skin on an
apple. Below that, it is an assumptive educated guess at best.
As far as sounding or deep sub surface imaging all we have is from seismic data that goes through the Earth and is received by imaging equipment for
very tenuous visual data. If you want to know more about this go here
for a hint to
how much we 'don't' know.
The Earth is active all the time and we have so little information about subsurface features other than different densities and some anomalous
features that we are likely only 2% smarter than we where 100 years ago.
There are unsubstantiated, or otherwise, classified information where massive underground caverns where found and likely 'used' by government
agencies of darker data retained. Deeper mines, mining and tunneling machinery used by such have some better information and likely research methods,
but to release this information is to reveal the methods and above top secret classified technologies used, so we are not getting that soon and will
stay dumb to that end.
This is why I am hoping we can accept the possibilities for extraterrestrial/trans-dimensional intelligence we have tons of evidence for. Then, when
we can accept contact and intelligently seek direct contact and knowledge exchange we will amplify our understanding of ALL subjects to unimagined
levels. So work for that cause! Until then all we can do is muddle along, groveling for understanding, scratching our butts, picking our snozzez and
slinging our waste out of the cage of an uneducated and sensation addicted society.
I am satisfied to experience such fascinating events as this and the beauty and mystery of this living world, and will of course approve of and watch
for new understanding from the study of such geologic events by our current sciences. Such as they are.
Other than that, to attribute such a small geo-effect to such 'global' or 'astronomical' implications are fairly useless unless you enjoy such
blue-sky speculation. Yea, could be true, but then the probabilities is infinitesimally small.
Sorry for the wet towel.
By the way, California's San Andreas Fault is showing a bit of unusual activity according to USGS scientists. I say this living less than 300 yards
from the Hayward fault which is the most active fault in the continental United States. It is more likely a threat it is said than the San Andreas. My
200 year old building is essentially kindling if the 'P' wave hits from that. In reality we have no idea what will go first. These or major faults
in very deep ocean areas causing worse effects to shorelines. FYI
