“…We tested USGS ShakeMap using the attenuation of the peak horizontal acceleration in the Dinarides area relations that were developed by Herak et al ([60], HMI01) and Markušić et al ([61], MHHI02) to the level of the average rock or very stiff soil sites (Figure 13a). We also selected three global, empirical ground-motion equations (GMPEs) that might be applicable to this region: (1) the hypocentral distance model of Akkar et al ([62], ASB14), which was derived using pan-European datasets and two NGA-WEST 2 models (referred to as NGA14) with weights of 0.5; (2) the model of Boore et al ([63], BSSA14) and 3the model of Chiou and Youngs ([64], CY14), which was tested by Šalić et al [65] for the Western Balkan BSHAP strong motion dataset (Figure 13b). Additionally, we tested the Bora et al ( [66], RVT-Bora14) model, which uses random vibration theory (RVT) to predict Fourier amplitude spectra and the duration of ground motion to estimate the response spectra from the RESORCE-2012 strong motion database of the SIGMA project.…”

The same RVT method was used by Skendrović ([67], RVT-Sk20) on the analogue recordings in the BSHAP strong motion database [65,68] and was used in this preliminary analysis, together with the Bora14 model, for comparison ( Figure 13c). Since this is a preliminary analysis and we do not have a full seismotectonic analysis of the fault mechanism, GMPE estimations were made for a strike-slip fault with a 90-degree dip using a point source distance model (R e = R JB and R hyp = R rup ), similar to [65].…”

On 28 December 2020, seismic activity in the wider Petrinja area strongly intensified after a period of relative seismological quiescence that had lasted more than 100 years (since the well-known M5.8 Kupa Valley earthquake of 1909, which is known based on the discovery of the Mohorovičić discontinuity). The day after the M5 foreshock, a destructive M6.2 mainshock occurred. Outcomes of preliminary seismological, geological and SAR image analyses indicate that the foreshocks, mainshock and aftershocks were generated due to the (re)activation of a complex fault system—the intersection of longitudinal NW–SE right-lateral and transverse NE–SW left-lateral faults along the transitional contact zone of the Dinarides and the Pannonian Basin. According to a survey of damage to buildings, approximately 15% of buildings were very heavily damaged or collapsed. Buildings of special or outstanding historical or cultural heritage significance mostly collapsed or became unserviceable. A preliminary analysis of the earthquake ground motion showed that in the epicentral area, the estimated peak ground acceleration PGA values for the bedrock ranged from 0.29 to 0.44 g. In the close Petrinja epicentral area that is characterized by the superficial deposits, significant ground failures were reported within local site effects. Based on that finding and building damage, we assume that the resulting peak ground acceleration (PGAsite) values were likely between 0.4 and 0.6 g depending on the local site characteristics and the distance from the epicentre.

“…The adopted seismic hazard model (Milutinovic et al, 2016) takes four GMPEs into account, chosen to be most appropriate for Western Balkan region (Salic et al, 2017). These are: Aetal14 (Akkar et al, 2014), Betal14 (Bindi et al, 2014), BSSA14 (Boore et al, 2014) and CY14 (Chiou and Youngs, 2014).…”

Horizontally curved concrete girder bridges have complex dynamic characteristics because of their asymmetry and non-uniform mass and stiffness distribution. Their seismic behaviour is considerably affected by various such as structural characteristics, radius of the superstructure curvature and local site conditions. The computational, three-dimensional (3D) bridge models consisting of concrete girders with concrete deck, single pier columns and caps were created in OpenSees analyzing a representative, three-, four- and five-span continuous curved concrete girder bridges in N. Macedonia. Different seismic hazard levels and soil conditions were chosen in order to perform site-specific hazard calculations to investigate the effect of critical curved bridge parameters on the seismic response using a group of representative bridges. Two levels of capacity were considered: damage and collapse limit state (DLS and CLS). The results from the performed extensive nonlinear analyses including uncertainties were used to estimate the influence of the number of spans, deck width, pier height, deck horizontal curvature radius and local site effects on the bridge performance. The influence of soil conditions and superstructure curvature are significant for the seismic vulnerability of girder bridges, especially those with more spans. With the increase of the superstructure curvature radius, the bridges become more vulnerable, particularly if they have more spans and are founded on soil of weaker characteristics. The difference in the probability of damage occurrence to bridges with smaller number of spans, regardless the curvature radius, is small if these are founded on a good base. In the case of CLS, such probability differs extensively, particularly in multi-span bridges founded on weak soil. Regardless the curvature radius and the soil characteristics, the width of the superstructure has a favorable effect upon the seismic response of the selected type of bridges. Bridges with piers of a greater height and greater curvature radius exhibit considerably less favorable seismic behavior than bridges of smaller curvature radius founded on better soil.

“…Earthquake-induced liquefaction phenomena have been mainly observed in the Periadriatic Depression during strong earthquakes of the 20th century [18,28,[33][34][35][36] (Figure 15a) as already mentioned in the respective chapters above. The third examined criterion was the classification of areas based on the seismic zonation and the seismic hazard maps of Albania [49][50][51][52].…”

Liquefaction Phenomena Induced by the 26 November 2019, Mw = 6.4 Durrës (Albania) Earthquake and Liquefaction Susceptibility Assessment in the Affected Area

On 26 November 2019, an Mw = 6.4 earthquake struck the central-western part of Albania. Its impact comprises secondary earthquake environmental effects (EEE) and severe building damage within the Periadriatic and the Tirana Depressions. EEE comprised mainly liquefaction phenomena in coastal, riverine, and lagoonal sites of the earthquake-affected area. From the evaluation of all available earthquake-related data, it is concluded that liquefaction sites are not randomly distributed within the affected area but are structurally and lithologically controlled. The affected areas are distributed within NW–SE striking zones formed in graben-like syncline areas with NW–SE trending fold axes. These graben-like areas are bounded by NW–SE striking marginal thrust faults and are filled with geological formations of Neogene to Quaternary age. These NW–SE striking zones and structures coincide with the NW–SE striking seismogenic thrust fault of the November 2019 earthquake as it is derived from the provided fault plane solutions. An approach for liquefaction susceptibility assessment is applied based on geological and seismological data and on liquefaction inventory. From the comparison of the compiled liquefaction inventory and the susceptibility maps, it is concluded that the majority of the observed liquefaction has been generated in very high and high susceptible areas.
