Natural Hazards, 1994
A simplified seismotectonic model is proposed for Bulgaria by introducing generalized seismogenic areas containing systems of complex geometry faults. A tectonic scheme, which considers the main faults only, is then derived from this. The assessment of the regional seismic hazard is done using different approaches: the Gumbel, the Cornell, and the ...

Seismicity, seismotectonics and seismic hazard of Italy
Engineering Geology, 2000Abstract A first generation of probabilistic seismic hazard maps of the Italian country are presented. They are based on seismogenic zoning deriving from a kinematic model of the structural tectonic units and on an earthquake catalogue with the foreshock and aftershock events filtered out. The following ground motion parameters have been investigated

Disaggregation of seismic hazard [PDF]
Bulletin of the Seismological Society of America, 1999 AbstractProbabilistic seismic hazard analysis (PSHA) integrates over all potential earthquake occurrences and ground motions to estimate the mean frequency of exceedance of any given spectral acceleration at the site. For improved communication and insights, it is becoming common practice to display the relative contributions to that hazard from the ...

Quantitative Seismic Hazard Assessment
2007We analyze the ingredients required for deterministic wave propagation simulation in order to estimate more accurately ground motion in terms of amplitude, frequency content and duration. Building maps of expected ground motion before a catastrophic event for various scenarios may help design ways to mitigate impacts of ground vibrations as well as ...

The devastating earthquake in Bhuj on 26 January 2001 highlighted the high earthquake risk in the Indian region of Gujarat. In their Perspective, Bilham et al. warn that major earthquakes may be expected in another part of India, the Himalayan arc.

The East African Rift System (EARS) and by extension the Davie Ridge, which is considered as the seaward extension of eastern branch (Kenya Rift Valley) of the East African Rift Valley (Mougenot et al., 1986), are characterized by divergence whose maximum rate is estimated to be about 7 mm/year (Chase, 1978).

This section explains the fundamentals of seismic hazard analysis as part of earthquake engineering. According to Elnashai and Di Sarno (Fundamentals of earthquake engineering: from source to fragility. Wiley, London, 2015), Earthquake Engineering is a branch of engineering concerned with the estimation of earthquake consequences and the mitigation of ...

Advanced Seismic Hazard Assessment [PDF]
Pure and Applied Geophysics, 2010 Issues pertaining to urban risks are a pressing concern for people involved in disaster mitigation. With the progressing urban sprawl and the emergence of mega-cities around the world, disasters of all kinds become an inevitable consequence of uncontrolled urbanization.

This chapter highlights the significance of Ground Motion Prediction Equations to estimate the seismic hazard at a region based on earthquake magnitude and source to site distance. A glimpse of both deterministic and probabilistic approaches for hazard assessment is presented along with a discussion on the logic tree framework.

This section deals with the seismic hazard computation process. It should be noted that, in cases where the seismic hazard to be calculated includes site-specific soil amplifications, this process may include two steps: hazard calculation for reference rock conditions and subsequent site response analysis to combine the local soil response with the ...
