* Experts consider that the earth should never have shaken so violently in the Schuan area. Then the investigators track a possible responsible. Their suspicions have even focused on apparently innocent people: the roadblocks. For example, the 3 Gorges dam is a larger reservoir than Switzerland! The Longmen Shan mountains host several active faults and the region's rivers support numerous dams including that of Zipingpu, a colossus of 156 m in height, located 5 km from the epicenter and which retains more than 1 billion meters water cubes. What lend the latter a role of triggering the earthquake.
FAILURE + DAM = EARTHQUAKE?
Indeed, during filling, the weight of the water causes underground breaks which allows the water to infiltrate up to several tens of km in order to be able to lubricate the faults, again breaking the balance of forces. If the only natural disaster whose origin was not enthropic, this latest discovery implies that human civilization now has an indirect effect on the earth's layer.

* Some very specific earthquakes, known as super-shear, only existed in theory. Today we know that these earthquakes which have the property of generating other earthquakes have a much more devastating effect than traditional earthquakes, not only by their speed of propagation [5 km / s!] But especially by its destruction potential. much higher. All evacuation and prevention methods for the population are therefore wrong! The worst part is that these super shear faults would be found in densely populated areas like San Andreas, California ...

Conclusion: Chance or coincidence of the Earth system? Or else Man has settled himself in earthquake zones, not because he is masochistic but because seismic faults have sheltered and / or have always sheltered watercourses [except, it is it indeed the quest for water that has shaped and will continue to shape human civilization] or is the Earth system considering Humanity as too parasitic violently responding?
James Lovelock's Gaia hypothesis stopped at the study of the self-regulation of the human species and the Biosphere / Anthropy interaction. The latest scientific findings prove that research is needed even further. James Lovelock prefers "Gaia Hypothesis" than "Gaia Theory" which has a "romantic connotation of the regulatory system of planet Earth". Perhaps this connotation implying "a consciousness of Gaia" displeases scientists, but admit that the coincidences (Tsunami, global warming, cyclone and now the earthquake of human origin) are disturbing.
Shouldn't the scientific debate be opened up to a philosophical debate in order to open up new avenues of scientific research? If each element enters into a "didactic and dialectical" relation with other elements, shouldn't the Earth system (Gaia) be considered as an element in its own right (and no longer as a container of all the other elements) which interact? with all the other elements? Just like the human species, which is also an element of the biosphere, shouldn't we integrate into the Earth system, the biosphere, the superficial lithosphere but also the deep lithosphere? Isn't this a possibility that would take into account the latest scientific discoveries in order to create a mathematical program modeling the functioning of planet Earth? This mathematical program would greatly reduce our TOTAL ignorance on the Earth system.
I no longer remember the source, but I read that according to scientific studies, it was suspected that during the 20th century, the strong increase in the number of earthquakes would be due, for 40% of them to explosions that would have played the role of trigger ...
