On a Quick Seismic Microzonation of Wide Areas
Pure and Applied Geophysics, 2005In this paper a characterization of seismic site response is proposed, taking into consideration geo-morphological conditions, geotechnical and geophysical parameters such as slope, average shear-wave velocity, maximum expected acceleration on bedrock, depth of ground water table.

Cluster Analysis to Support Microzonation Studies
Proceedings, 2015In recent times the use of microtremor techniques for subsoil investigation increased significantly. The use of HVSR (Horizontal to Vertical Spectral Ratio)technique for seismic microzoning studies allows in many case to obtain detailed reconstruction of the roof of the seismic bedrock and to identify areas with similar seismic behaviour. Two different

Microzonation for Earthquake Scenarios
2010Seismic microzonation involves generation of seismic hazard maps with respect to estimated ground motion characteristics on engineering bedrock outcrop based on a regional seismic hazard study compatible with the scale of the microzonation. A grid system is implemented dividing the investigation area into cells according to the availability of ...

Seismic microzonation in Australia
Journal of Asian Earth Sciences, 2000Abstract Since the 1980s seismic microzonation studies have been undertaken in Australia to assess the likely effects of earthquakes on urban centres built on unconsolidated sediments. Presently the Nakamura method is used for processing data. So far parts of Perth, Adelaide, Cairns, Gladstone, Rockhampton, Newcastle, Sydney and Launceston have been

The antiresonance phenomena in seismic microzonation
Earthquake Engineering. Construction Safety, 2021The interference of incident and reflected seismic waves in the ground massif near the day surface is the cause of resonant effects. In the practice of seismic microzonation (SMZ), a resonant increase in the total seismic intensity is of particular importance.

A GIS for Data Mining in Seismic Microzonation Studies
2019The increasing spread of geographical information system (GIS), which represents a recognized technology that is mainly composed of data handling tools for storage, recovery, management and analysis of spatial data, made research and the application of automatic and semi-automatic cartographic techniques extremely interesting. The creation of a GIS for

Microzonation of Bucharest: State-of-the-Art
Pure and Applied Geophysics, 2004The 1940 (Mw 1⁄4 7.7) and 1977 (Mw 1⁄4 7.4) Vrancea earthquakes (Romania) inflicted heavy damage and casualties in Bucharest and the statistics indicate a recurrence interval of 25 years for Mw ‡ 7.0 events. Under these circumstances, the seismic microzonation represents important information for detailed urban planning that establishes an appropriate ...

Seismic microzoning in Skopje, Macedonia [PDF]
, 2017 Seismic microzonation maps for Skopje (Macedonia) are presented based on the Uniform-Hazard-Spectrum (UHS) methodology. UHS satisfies the guidelines for performance-based design (PBD), which require specification of two sets of spectral amplitudes, one for which the structure will remain essentially linear, and the other for which it will undergo a ...

Seismic microzonation of the island of Montreal
2004Montreal is the third largest city in Canada according to the size of its population, and ranks second in terms of seismic vulnerability. In the past decades many studies of the soil deposits of the Montreal Island have taken place without considering the influence of unconsolidated soils.
