Abstract
In this article we examine the siesmicity of Kerman city. This city is located in a compressional graben which is bordered by several active faults, some of them are able to trigger an earthquake even stronger than Ms=7.0. Numerous historical earthquakes had occurred around the city which caused minor damage to the building. For seismic evaluation of Kerman city both probabilistic and deterministic methods have been taken into consideration. Accordingly, peak ground acceleration due to 15 fault segments can exceed greater than 0.2g. The intensity scale resulting from earthquakes by Kerman – Zangiabad, North Kerman and Ekhteiarabad faults would be around IXMMI in the city. In order to assess the site effect, semi detailed micro zoning was carried out by combining micro tremor and sediment facies maps using GIS. The thick young sediments would amplify the intensity to X+ MMI. Based on the resulting map, the intensity scale would increase in central, western as well as some localities of the southern part of Kerman and many buildings would be damaged by such intensity scale.
