Ein strategischer erdbebenresilienter Wiederaufbau unter Verwendung von GIS basiertes weighted Overlay.

Abstract

Earthquakes are a natural phenomenon that can cause severe destruction within urban areas. In particular, cascading effects resulting from the earthquake, such as liquefaction, fires, landslides and tsunamis, can increase the resulting damage. In addition, current experience shows that strict building regulations, such as specifications on statics and the design of the building structure, and strategic planning by the city, are the best way so far to minimise damage from earthquakes. On 06.February 2023, Turkey was hit by two strong earthquakes. The earthquakes caused enormous destruction, killing many people. In particular, the city of Antakya, within the southeastern province of Hatay, was hit very hard by the two earthquakes. The magnitude of the earthquakes within the hit provinces varies according to the local topographical, geomorphological and hydrological conditions. As a basis for this work, the local conditions in the study area of Antakya are to be investigated and evaluated so that the areas with high or very high risk can be identified. The identification of the risk areas will result in a map that can be used as a basis for establishing new planning measures. These planning measures result from the literature research, whereby three best practice examples were taken into focus. The three case studies from Haiti, Chile and Japan have designed different measures for earthquake-resilient urban planning. In addition, supplementary measures are to be taken from other concepts and scientific work in order to be able to identify further suitable measures. The identified measures are to be integrated into the basic map. The result should be a strategic master plan, which should combine different measures at the urban level.
