The westernmost part of the Czech Republic and adjacent area in Germany is known for the geodynamic activity represented by earthquake swarms
and large-scale degassing of CO2 fluids. The region is also characterized by numerous mineral springs, Tertiary/Quaternary volcanism and neotectonic
crustal movements, located at the intersection of two major intraplate fault zones, the Eger Rift and the Marianske Lazne Fault. It is likely that all
these phenomena are related to a common origin. Geodynamic activity, fluids and earthquake swarms represent a unique phenomenon worldwide. Currently,
it is well accepted that many earthquake swarms are driven by fluids in the crust. However, it is still unknown how fluids are driving the persistent
earthquake activity. Long-term monitoring is essential to understand these phenomena and their interactions and answer these questions.
