The Ruhr River Association and the Geological Survey of North Rhine-Westphalia operate a seismic station at the Ennepe Dam. This masonry dam was supplementary heightened by an amount of 10 m. Caused by this unfavourable geometry for dynamic loading, the dam is potentially sensible to ground motion effects due to earthquakes. The seismic station is integrated into the new Earthquake Alerting System (EAS NRW). With 14 stations the system monitors the local seismicity enabling an automatic analysis of location and magnitude in case of damaging events. Redundant transmission channels to independent analysis computers provide the accessibility and functionality of the system.

For one year the online-information-system «Danger potentials of the underground in NRW» informs property owners, house builders, architects, authorities on the building areas and planning agencies, about potential dangers of the underground. The system is a modern E-Government-Application that provides the user an opportunity to achieve a general idea of established or possible danger potentials fast and free of charge. The system is accessible via www.gdu.nrw.de and allows the user to obtain a preliminary information without contacting an authority. An online-application form enables the user to request information relating to the property. Now the information system received the GIS Best Practice Award 2010 by the DVWe. V. at the INTERGEO® 2010 in Cologne.
