An awakening volcano in the Vogtland / Bohemia? - Findings, open questions and consequences.
Between Marienbad and Leipzig / Halle it quivers almost constantly at depths of about 20 to 6 km. Since the magnitudes are usually below 1.5, this is not noticeable to humans. In the last 30 years, medium-sized swarms between magnitude 3 and 4 have repeatedly appeared in the southern Vogtland and in northwestern Bohemia, which are the reason for the constant interest of the population. The lecture deals with the origin of CO2-dominated gases, recent hidden magma activity, earthquake activity as well as quaternary volcanism in Western Saxony and parts of West Bohemia and Northeastern Bavaria. Time series studies using helium isotope on gases from mineral springs and mofettes revealed anomalies in the spring of 2000 and 2006 that were considered concealed, i. non-terrestrial magma intrusions were interpreted. At Mytina / CZ and Neualbenreuth / D, unknown volcanoes (Maare) Quaternary (Middle Pleistocene) ages were discovered in 2007 and 2015. To what extent does this fit together? Will the region threaten volcanic eruptions in the future? Which open questions are asked by science and which research approaches and methods should they be processed in the future and solved (<https://web.natur.cuni.cz/uhigug/icdp/articles.php>)? What contribution in collaboration with researchers could the media and politics make in the future?
