Dr. Stine Gutjahr

studied geophysics at the Freie Universität Berlin where she received her diploma in 2009. For her diploma thesis she performed wavefield separation to the recorded wavefield of an active seismic data set from the San Andreas fault at Parkfield and separately imaged the P-, S- and converted components of the wavefield. Stine finished her PhD in 2015. For her thesis she reprocessed an old industry seismic reflection data set in order to gain additional structural information of the deep crust and upper mantle of the San Andreas fault zone using advanced imaging techniques. Currently she focuses on the detection and location of microseismic events and the processing of refraction seismic data.

Dr. Peter Wigger

received his Diploma in Geophysics 1977 from the Freie Universität Berlin (FUB). Then he worked in the exploration company PRAKLA-SEISMOS. He returned to the FUB and was engaged in a number of projects exploring the continental lithosphere by controlled source seismology. 1983 he finished his Ph.D. at the FUB (thesis about the Apennin mountain chain and the geothermal anomaly in Tuscany, Italy) and since that time his research was focussed to the South American Andes, using wide and steep angle seismics as well as seismological methods. Since 1985 he also acted as the research manager for two large interdisciplinary geoscientific programs based at the FUB: Research Group "Mobility of active continental margins" (until 1990) and Collaborative Research Center (SFB 267) "Deformation Processes in the Andes" (until 2005). In 2012 he retired and now acts as adviser of the group.
