Section 2.1: Physics of Earthquakes and Volcanoes

The main target of this project is to systematically reanalyse and compare earthquakes and swarm parameter in the larger W-Bohemia / Vogtland region over the last 4-5 years using innovative full waveform methods run over the continuous 100 HZ data streams, and to assess the earthquake swarm close to Nový Kostel since 2020 with machine learning and template matching techniques by exploiting the 60-channel, 1000-Hz data stream of the ICDP Landwüst 3D array together with high quality key stations at the swam epicenters.

To study earthquake swarms, crustal fluid flow, mantle-derived CO2 and helium degassing, and processes of the deep biosphere, a new geodynamic multi-parameter in situ laboratory at depth is being established in the framework of the ICDP project “Drilling the Eger Rift”.

The potential of deep geothermal energy in Europe will only be exploited in the future if demonstrations of energy production from deep geothermal energy are successful. lt is therefore crucial that a procedure is implemented before drilling the next deep well, which minimizes the risk of field exploration.

The management of the post mining regions in Europe is important issue for the safety and economic reasons. The PostMineQuake traits the most important hazard related to unexpected ground motion.
