Historical seismicity of the Rijeka region (northwest external Dinarides, Croatia); Part I, Earthquakes of 1750, 1838, and 1904 in the Bakar epicentral area; discussion

Sites of high seismic intensities (VI-VIII) during the 1750 Rijeka, Croatia, earthquake correlate first with the Bakar-Vinodol thrust (or fault zone), one of the main features accommodating convergence in northern Adria; and second, with a fault derived from inversion/elastic dislocation modeling of tectonic, differential subsidence of submerged coastal notches. We can hence conclude that a segment of the Bakar-Vinodol thrust reactivated during the 1750 and possibly previous earthquakes, also explain increased coastal subsidence in the parts of the Bakar area.
