Beyound the tectonic activity, how any human activity can lead to, or reinforce a siesmic activity?
Destructive earthquakes in the earth's crust occur in areas that are in a compressed state and do not “pass” waves of geodeformations through them. In this situation, the energy of deformation waves (tides in the solid body of the Earth) “breaks” a given section of the earth’s crust.
People are extracting oil, gas, and water from the earth's crust. Does this lead to compression of the earth's crust? Seismologists are recording an increase in microseismicity.
People build cities and create reservoirs. Does this lead to compression of the earth's crust? Seismologists are recording an increase in microseismicity.
In permafrost areas, human activity increases the temperature and the permafrost melts. Does this lead to compression of the earth's crust? Seismologists are recording an increase in microseismicity.
Yes. The wireless frequencies (radar) emitted by the antennas located on the blocks of flats and inside them (through applications) and the accumulation of the energies of the standing waves resulting from the action of the waves 24 out of 24 hours in long time intervals (years).
In my article 'The driving forces of tectonic activity' on RG I try to find a classical hydrodynamic explanation for tectonic activity including earthquakes. The recent massive earthquake in northern Africa can be seen as a result of a common movement of all continents in a northern direction.
Reservoir-induced seismicity has been known for some time. Hydroelectric dams with large reservoir (artificial) lakes would affect the rocks under the lake, especially if the ground has not been studied prior to construction of the dam.
In my area this phenomenon has been observed. Many earthquakes up to Richter scale 4 have taken place around the reservoir lake, which did not happen prior to the filling of the lake.
The Hydro company built several more hydroelectric plants since then, but without any artificial lakes. They must have known that big lakes had problems.
I proposed a geological study of the area, but the Hydro refused.
