In order to reach a new level of high-frequency, near-source and multiparameter observation of earthquake swarms and related phenomena, such a laboratory comprises a set of shallow boreholes with high-frequency 3-D seismic arrays as well as modern continuous real-time fluid monitoring at depth and the study of the deep biosphere. This laboratory is located in the western part of the Eger Rift at the border of the Czech Republic and Germany (in the West Bohemia-Vogtland geodynamic region) and comprises a set of five boreholes around the seismoactive zone. To date, all monitoring boreholes have been drilled. This includes the seismic monitoring boreholes S1, S2 and S3 in the crystalline units north and east of the major Novy Kostel seismogenic zone, borehole F3 in the Hartousov mofette field and borehole S4 in the newly discovered Bazina maar near Liba. Supplementary borehole P1 is being prepared in the Neualbenreuth maar for paleoclimate and biological research. At each of these sites, a borehole broadband seismometer will be installed, and sites S1, S2 and S3 will also host a 3-D seismic array composed of a vertical geophone chain and surface seismic array. Seismic instrumenting has been completed in the S1 borehole and is in preparation in the remaining four monitoring boreholes. The continuous fluid monitoring site of Hartousov includes three boreholes, F1, F2 and F3, and a pilot monitoring phase is underway. The laboratory also enables one to analyze microbial activity at CO2 mofettes and maar structures in the context of changes in habitats. The drillings into the maar volcanoes contribute to a better understanding of the Quaternary paleoclimate and volcanic activity.}, language = {en} } @article{FischerHrubcovaDahmetal.2022, author = {Fischer, Tom{\´a}š and Hrubcova, Pavla and Dahm, Torsten and Woith, Heiko and Vylita, Tom{\´a}š and Ohrnberger, Matthias and Vlček, Josef and Horalek, Josef and Dedecek, Petr and Zimmer, Martin and Lipus, Martin P. and Pierdominici, Simona and Kallmeyer, Jens and Kr{\"u}ger, Frank and Hannemann, Katrin and Korn, Michael and Kaempf, Horst and Reinsch, Thomas and Klicpera, Jakub and Vollmer, Daniel and Daskalopoulou, Kyriaki}, title = {ICDP drilling of the Eger Rift observatory}, series = {Scientific drilling : reports on deep earth sampling and monitoring}, volume = {31}, journal = {Scientific drilling : reports on deep earth sampling and monitoring}, publisher = {Copernicus}, address = {G{\"o}ttingen}, issn = {1816-8957}, doi = {10.5194/sd-31-31-2022}, pages = {31 -- 49}, year = {2022}, abstract = {The new in situ geodynamic laboratory established in the framework of the ICDP Eger project aims to develop the most modern, comprehensive, multiparameter laboratory at depth for studying earthquake swarms, crustal fluid flow, mantle-derived CO2 and helium degassing, and processes of the deep biosphere.
