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.

    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.

    Dynamic characteristics of site such as predominant periodamplification factor, shear wave velocitystandard penetration test values can be used for seismic microzonation purpose.

    Here, the emphasis is on the determination of the distribution of shear wave velocities in near surface sediments and rock using seismic methods. Thomas Spies. Seismic microzonation can be considered as the preliminary phase of earthquake risk mitigation studies.

    The subject of seismic microzonation is the determination of variations of the ground motion amplification due to local differences in the geological conditions and topographical characteristics site effects, Fig. This kind of trapping of waves created a resonance and consequently resulted in an enormous amplification of the ground motion.

    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.

    The Mexico City earthquake of September 19, is a good example of earthquake damage to a modern city built on soft sediment.

    The Mexico earthquake of September 19, Relationships between soil conditions and earthquake ground motions. Microtremor observations are easy to perform, inexpensive and can be applied to places with low seismicity as well, hence, microtremor measurements can be used conveniently for microzonation.

    1. This kind of trapping of waves created a resonance and consequently resulted in an enormous amplification of the ground motion. Views Read Edit View history.

    2. Thereby, an important contribution to the mitigation of the expected earthquake damages is achieved. It has long been recognized that the intensity of ground shaking during earthquakes and the associated damage to structures are significantly influenced by local geologic and soil conditions.
