Engineering Geological Aspects for the Microzonation of the City of Volos, Greece

Abstract

The city of Volos located at the foot of the Peninsula of Pelion at Central Greece experienced several strong earthquakes during the previous century. The engineering geological conditions of the city have been analyzed using a relational geotechnical database management system, while the city subsoil has been grouped into five geotechnical units. The maps showing the contours of the depth to bedrock head and the ground zoning against seismic hazard were compiled through GIS. For the compilation of the latter map, a set of unified classification criteria was proposed based on the Greek Seismic Code (EAK 2000).

Evaluation of Open Geotechnical Knowledge in Urban Environments for 3D Modelling of the City of Seville (Spain)

“…In this case, the information usually comes from the use of geotechnical surveys that have a smaller territorial scope. These surveys include the use of linear inspections using specialised equipment such as Ground Penetrating Radar [15], punctual information from seismic acceleration records [16], in situ resistance tests [17], and data from samples collected in pits and boreholes [18]. This type of approach is even more necessary in urban areas, where the complexity of the layers of existing land information is very high [19].…”
