Events Seismic Waves in Laterally Inhomogeneous Media VI The international workshop “Seismic Waves in Laterally Inhomogeneous Media VI” was held at the Castle of Hrubá Skála, Czech republic, June 20-25, 2005. The workshop was organized by the Geophysical Institute, Acad. Sci. CR and the Charles University, the Faculty of Mathematics and Physics. As in all previous workshops held under the same name at the Castles of Liblice (1978, 1983 and 1988), Třest (1995) and Zahrádky (2000), the workshop was again oriented mainly on theoretical and computational aspects of seismic wave propagation and generation in complex structures, and on applications involving these aspects in seismic exploration, Earth's crust studies and, newly, also in non-destructive material testing. The main topics were forward and inverse modelling of seismic wave fields in laterally inhomogeneous, isotropic and anisotropic structures. The workshop was attended by about 60 researchers from 14 countries. The next workshop is planned for 2010. Several of the contributions presented at the workshop are going to be published in a special issue of Studia geophysica et geodaetica in 2006. 59
Drilling the Eger Rift in Central Europe, Courtyard Býkov, October 3-7, 2004 The workshop, organised in the framework of and financially supported by the International Continental Scientific Drilling Program (ICDP), was aimed at discussing the scientific goals that would justify deep drilling in the western part of the Eger Rift area. The Eger Rift, located in the northwestern part of the Bohemian massif, is a world key site that has attracted the international geoscience community for many decades. The rift is the result of young, deep-seated geodynamic processes manifested by episodic Cenozoic volcanism (the youngest at 0.2-0.5 Ma), repeated earthquake swarms, numerous mineral springs, CO 2 emissions with high 3 He content, and abundant mofettes. The crust-mantle boundary (27 km) and lithosphere–asthenosphere boundary (80-90 km) are uprised compared to the conditions in the Bohemian massif. Also surface heat flow is the highest within the massif (60-80 mWm -2 ). Owing to the diversity of available data stretching over various fields of geoscience, the area is an ideal place to foster studies on the interaction between an active mantle, crust, and deep biosphere processes. Thus, the workshop formed a platform on which the state of the art in investigating the rift was summarized and new research targets addressed by drilling were defined. According to the interacting research fields, the workshop was streamed into six topical blocks: Geology, Tectonics, and Fluids; Evolution of the Lithosphere; Earthquake swarm processes; Fluid- Related Seismic Processes, Deep Biosphere and Drilling and Borehole Monitoring. At the end of the workshop, a field trip introduced the participants to key sites in western Bohemia including the thermal springs at Karlovy Vary Spa, the potential drilling site in the northern part of the Cheb sedimentary basin (in the vicinity of the seismically dominant Nový Kostel earthquake focal zone), the Bublák mofette (surrounded by seismic stations of the WEBNET (Academy of Sciences, Prague) and KRASNET (Brno University) networks, the CO 2 exhalations at Soos, and the Železná Hůrka volcano and its tephra deposits. 65 participants attended the workshop.
