I am aware that, while I have provided logic, I have not provided the mechanism linking human induced earthquakes (in US or elsewhere) with recent strong earthquakes in Croatia, and precursor
earthquakes in Croatia with global seismicity, but the theory implies such mechanism exists.
One possibility is resonance induced amplification - tremors produced by humans are producing pressure waves of specific frequencies. A resonance at specific places in Earth would accumulate
energy (ie. thermal expansion) which upon reaching a threshold could trigger another chain of events, including stronger earthquakes.
As for planetary neurogenesis in general, it implies some large scale DNA code [precursor] equivalent exists.
One of my hypotheses is that Earth is a large scale quantum system, or at least a quasi-quantum system. This implies entanglement of events in time (correlation of past and future, not
causation), and superposition. I have hypothesized elsewhere that
evolution
on Earth is, to a significant degree, guided through mental pathways (I also hypothesize elsewhere that mental symbiosis of beings, such as in biofilms, is a precursor to
a DNA coded organism), and the code connecting phenomena is thus hidden in time dimension. It is not yet encoded in large scale DNA sequences, as it is on small scale in individual quanta of
evolution (ie.
pulses of individual biotic life).
Evolutions on adjacent vertical scales of energy, postulated in
Complete Relativity (CR), are
entangled.
According to CR, to conserve relativity, relatively equivalent natural processes must occur at different scales of energy (generally separated in time, but connected through channels of
entanglement on a 3rd scale), so this is simply how nature works. We cannot be aware of all mechanisms on all scales at all times - as proved in Quantum Mechanics (QM).
One can perform many experiments on small scale and confirm many effects predicted by QM - but, one obviously cannot prove planetary neurogenesis in similar way. Is that a reason to ignore the
predicted effect on large scale?
Apart from logic, analysis of past events and current events on Earth are all that is available as evidence on Earth's scale - if the theory is correct, this civilization, as it is, has only one
chance to accept whatever is available as evidence.
I am not suggesting one to rely on faith, I'm merely suggesting it would be foolish to discard the available evidence because it cannot be further confirmed by growing and destroying
billion Earths billion times in an [bio]accelerator.
Tephra is fragmental material produced by a volcanic eruption regardless of composition, fragment size, or emplacement mechanism.
The Volcanic Explosivity Index (VEI) is a scale that describes the size of explosive volcanic eruptions based on magnitude and intensity. The numerical scale (from 0 to 8) is a logarithmic
scale, and is generally analogous to the Richter and other magnitude scales for the size of earthquakes.
However, when the
The volcanic ejecta needs to reach the stratosphere for a significant cooling effect. As the troposphere warms it expands in height, making it harder for particles ejected in smaller eruptions
to reach the stratosphere.
Therefore, generally, smaller eruptions might be decreasing with the appearance of ultra-massive eruptions (due to long-term warming effect).
However, in case of major extinctions (when life should be migrating toward the mantle within a relatively short time-frame) this decrease is unlikely.
