Landslide database - RDB: Earthfall
Description
In Rhineland-Palatinate there are always mass movements. The Landslide Database Rhineland-Palatinate is a joint project of the State Office for Geology and Mining Rhineland-Palatinate (LGB) and the Forschungsstelle Rutschungen e.V. at Johannes Gutenberg University Mainz (FSR). Originally, the database was created at the then State Geological Office and continued at the Research Centre for Landslides. Since 2009, the two cooperation partners have been working together on a complete reprocessing. The database includes landslides, rockfalls, rockfalls, earthfalls and daybreaks in Rhineland-Palatinate. In total, there were 2,291 claims (as at: 01.06.2012), which were mainly recorded and archived by the two project partners LGB and FSR in the field. Further data come from various diploma theses and dissertations, which were supervised by the aforementioned institutions. The oldest documented case of damage occurred in 1655. Most events cover the period from 1950 to the present day. The MS Access database based on Oracle, which is specially programmed in the LGB, contains 33 different data fields, which include information on the location, geology, causes and safeguards of the mass movement. The data sets are mainly recorded by means of specially created lists of terms in order to ensure uniform documentation. The online presentation, which was created on the basis of the landslide database, shows in which areas of Rhineland-Palatinate mass movements have occurred so far. It is aimed at municipalities, engineering offices, planners, appraisers, architects and interested citizens who use this information, among other things, for the planning and preliminary exploration of construction projects. The aim is to provide clues about the range of mass movements. Possible problematic areas can thus be identified in good time, examined accordingly and an adapted approach taken. The Mapserver application represents systematically arranged tiles with an extension of 1 x 1 km, the color variation of which is due to the number of mass movements within the tile. It is expressly pointed out that for data protection reasons, a pinpoint, parcel-sharp location representation of the mass movements is dispensed with. A concrete reference to the location and the associated inference to individual plots of land are thus excluded. Furthermore, it is pointed out that the representation of a mass movement within a tile does not mean that this danger is present throughout the entire tile. Likewise, the lack of information on mass movements does not mean that they can be completely excluded there. In addition, the classification says nothing about the current activity. Planned construction projects within a tile affected by mass movements do not necessarily have to pose problems, so it is also pointed out in this context that the hazards shown here do not replace spot and object-related investigations or on-site assessments. Due to the natural solution of carbonate, sulphate or salt rocks, underground cavities are formed that can collapse. As a result, a collapse funnel with diameters of up to several meters is created on the earth's surface. An earthfall occurs primarily in soluble rocks.
