High-resolution space-borne remote sensing data are investigated for their potential to extract relevant parameters for a vulnerability analysis of buildings in European countries. For an evaluation of large earthquake scenarios, the number of parameters in models for vulnerability is reduced to a minimum of relevant information such as the type of building (age, material, number of storeys) and the geological and spatial context. Building-related parameters can be derived from remote sensing data either directly (e.g. height) or indirectly based on the recognition of the urban structure type in which the buildings are located. With the potential of a fully-or semi-automatic inventory of the buildings and their parameters, high-resolution satellite data and techniques for their processing are a useful supporting tool for the assessment of vulnerability.

“…These hazard estimates include uncertainty and error ranges for input data using the logic-tree-method as well as new data regarding seismogenic potential of earthquake source regions in Germany (sub-project B1; Gru¨nthal and Wahlstro¨m, 2006). The earthquake hazard estimation at this scale is supported by the compilation of neo-tectonic data (sub-project C2, Goebell and Wetzel, 2006) and data regarding the strain-field. At the regional scale the work focused on the city of Cologne and its surrounding area.…”

Possibilities and Limitations of Interdisciplinary, User-oriented Research: Experiences from the German Research Network Natural Disasters

et al. 2006

The German Research Network for Natural Disasters (DFNK) linked 15 partners with scientific expertise in the field of natural hazards. Main objectives were the development and provision of the scientific fundamentals for an advanced risk management of important natural disasters in Germany, i.e., floods, earthquakes, storms and wildland fires. This included risk analyses, the development of information systems for supporting disaster management, and recommendations for risk reduction measures. This paper gives an overview of DFNK and summarises its experiences concerning multidisciplinarity and user-orientation. It illustrates the concept of risk chains, causally linking the different processes from hazard to risk. The step from hazard to risk requires interdisciplinary research teams. The experiences show that integrative concepts allow results not achievable with mono-disciplinary approaches. Integrative approaches pave the way to harmonised safety considerations taking into account the different hazards in a region within a common framework. User-orientation, policy advice and development of operational tools are key issues of disaster research. The experiences of DFNK illustrate the limitations of a research network in bridging the gap between research and application within rather short-term projects. Successful cooperation with users could be established by those activities where, at the beginning of the project, a user was identified who had a strong interest in solving an urgent problem.

“…Thus, they did not have a detailed assessment of the crustal deformation in Germany. Little work has been studied throughout Germany with a sparse GNSS network but with a timespan that is not yet long enough for a complete analysis of Earth's surface deformation (Goebell & Wetzel, 2006). So far, there has been a lack of in-depth GNSS-based investigations of neotectonic monitoring over the entire of Germany.…”

The crustal motions throughout Germany have not yet been fully understood because the research scope of previous studies mainly focuses on some active grabens. Thus, we investigate it in detail to identify the neotectonic motion characteristics and specific deformation-ongoing regions. High accuracy for monitoring and data analyses is required because the expected crustal deformation in Germany is small. We use high-precision GNSS time series processing techniques and interdisciplinary data to reflect actual motions and determine the causes of deformation. Also, an advanced technique of discontinuity correction is introduced to unify the fragments of the GNSS coordinate time series for better velocity field reliability. Our findings show that the Earth’s crust in Germany tends to increase at a maximum speed of +1.0 mm/yr. Meanwhile, local subsidence of around -0.8 mm/yr is concentrated in the river basins (e.g., the Rhine, Ems, Elbe, Northern Oder, and Danube) and extensive mining regions. The Earth’s crust here also behaves with noticeable compressions. The intra-plate motion in Germany is ∼0.8 mm/yr. A special region with an extension rate of +4.3 nstrain/yr is observed along the North-South trending Regensburg-Leipzig-Rostock shear zone. Machine Learning clusters the 3D plate velocity field into three distinct regions with increasing speeds: Northwest, East, and Southwest. Significant surface deformations are detected mainly in the Upper Rhine Graben, Eifel volcanic field, and Thuringian-Vogtland slate mountains. The harmonic motions of the Earth’s crust in Germany have an amplitude of ∼4.7 mm, in which the surface loads contribute half to this type of motion. The findings will contribute to the overall picture of neotectonics here.
