A microzonation study deals with the classification of hazards in a town or city terms surface ground motions that result from amplification and resonance frequency soils against seismic tremors. This paper presents peak amplitude for Lahore city, Pakistan. In order to recognize local soil effects covered geology at 159 sites horizontal-to-vertical spectral ratio (HVSR) Nakamura method was impl...

Being a country exposed to strong seismicity, the estimation of seismic hazard in Tajikistan is essential for urbanized areas, such as rapidly growing capital city Dushanbe. To ensure people’s safety and adequate construction work, detailed microzonation key proper planning. Existing estimations date back 1978; they are based on engineering geological investigations observed macroseismic data. ...

The analysis of ambient vibrations represents a valuable tool in seismic microzonation, engineering seismology, and other fields. An extensively used approach for the study of ambient vibrations is the use of array processing techniques. We have developed a novel technique for the analysis of the seismic wave field and show an application to the analysis of ambient vibrations. We derived maximu...
