Microzonation provides the basis for site-specific risk analysis, which can assist in the mitigation of earthquake damage. Spies bgr. Thomas Spies. A seismic zonation map for a whole country may, therefore, be inadequate for detailed seismic hazard assessment of the cities. Modern cities built on soft sediments are especially vulnerable to damage caused by amplified ground motions.
is the process of assessment of the source & path characteristics and local geological & geotechnical characteristics to provide a basis for estimating and mapping a potential damage to buildings, in other words it is the quantification of hazard. This study presents an overview of seismic microzonation and existing methodologies with a newly proposed methodology covering all aspects.

PDF | Seismic micro hazard zonation is the first step towards a seismic risk A methodology for seismic microzonation using GIS and SHAKE; a case study from.
Thus particularly endangered sites can be separated from less vulnerable ones. Microzonation Microzonation is a relatively young work area of seismology which is strongly interlinked with both engineering seismology and engineering geology. These changes in the earthquake impact can in turn cause serious differences in the grade of damage even at sites at short distance to each other.

Prominent examples for the great differences in the grade of damage in nearby areas caused by the same earthquake local site effects are the earthquakes in Mexico Fig. Spies bgr. This necessitates the development of microzonation maps for big cities for detailed seismic hazard analysis. Categories : Earthquake and seismic risk mitigation Earthquake engineering.
This paper presents an automated methodology for performing geographic information system (GIS)-aided seismic microzonation studies.
It presupposes the. demonstrate the applicability of the methodology proposed in the Seismic Microzonation Manual prepared for the project. The major contributions of the study.

Duration and strength for the earthquake recorded from the station on soft sediments are strongly amplified Source: After Stone et al. Ambient Vibrations measurement also called Microtremor has become a popular method for determining the dynamic properties of soil strata and is being extensively used for microzonation.
