Seismic hazard mapping of Ohrid, North Macedonia
Earthquake Engineering and Resilience, Volume 2, Issue 1, Page 111-130, March 2023., 2023 A seismic microzonation study is presented for the city of Ohrid in North Macedonia, an important World Heritage Site, exceptionally rich in archeological, architectural, and cultural sites. The Uniform Hazard Method was used to compute the amplitudes of strong motion, with explicit consideration of the geological site conditions.

Earthquake Spectra, Volume 39, Issue 1, Page 310-334, February 2023., 2023 A novel probabilistic methodology for regional seismic site characterization is proposed and applied to a region with highly heterogeneous surficial geology and varying soil sediment thickness and stiffness. The method combines various sources of geological and geotechnical uncertainties to develop a three‐dimensional (3D) shear‐wave velocity (Vs ...

A hybrid model for mapping simplified seismic response via a GIS-metamodel approach [PDF]
, 2014 In earthquake-prone areas, site seismic response due to lithostratigraphic sequence plays a key role in seismic hazard assessment. A hybrid model, consisting of GIS and metamodel (model of model) procedures, was introduced aimed at estimating the 1-D ...

Preventive planning model for rescue priority management in seismic emergency [PDF]
, 2018 Natural materials, such as soils, are influenced by many factors acting during their formative and evolutionary process: atmospheric agents, erosion and transport phenomena, sedimentation conditions that give soil properties a non-reducible randomness by

Seismic microzoning of the Delhi metropolitan area, India— I: Seismicity modeling
Earthquake Engineering and Resilience, Volume 1, Issue 2, Page 115-137, June 2022., 2022 This is part I of our seismic microzoning study of Delhi, India, metropolitan area, which presents the modeling of the seismicity. The a and b values of Gutenberg–Richter law, the maximum magnitude, Mmax, and the predominant focal depths, H, were estimated for a large region (24°–33° North latitude and 72°–82° East longitude), with a grid size of 0.1°.

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 5, May 2022., 2022 Abstract We analyzed 12 years of continuous seismic data acquired by two seismic stations in Central Apennines (Italy) with the aim to investigate the temporal variations of H/V spectral ratios. The two stations are located in the epicentral areas of the main strong motion earthquakes occurred in Central Italy in the last 12 years (L’Aquila 06 April ...
