We focused on geomechanics/geophysics and modelling the mechanical behaviour of the Earth’s crust (lithospheric plates). The main theme was the investigation of exogenous factors in crustal phenomena. Exogenous factors include e.g. tidal forces, cyclic changes in crustal temperature caused by the Sun, repeated changes in atmospheric air pressure, wave energy transfer from water bodies (seas and oceans) into the crust, etc. This paper (extended abstract of presentation) will show conclusions from models that address the effect of surface temperature changes on the behaviour of the Earth’s crust. One of the outputs was a calculation of the temperature field over a
time interval of two years.
We then created a similar model focusing only on temperature. It is a recursive algorithm to calculate changes in the temperature field in the Earth’s crust based on the surface temperature. The results of both models showing the heat penetration into the deep crust are consistent with the measurements. Based on this recursive algorithm, we estimated the amount of thermal energy stored in the Earth’s crust. In this way, the time it takes for half of the stored energy to be released back into the atmosphere can be determined. The most likely value for this parameter t1/2 is 270 years, which means that the amount of energy in the entire Earth’s crust is now at its maximum. This is due to anomalously high solar activity. The future cumulative solar energy in the Earth’s crust is estimated based on estimates of the evolution of solar activity. The results show a small increase in accumulated energy up to 2060 and then a smaller or larger decrease in accumulated energy and hence a decrease in global surface temperature.
