Active Tectonics of the Central Adriatic Region: New Insights from the Recent March 2021 Seismic Sequence (Mw5.2)
The central Adriatic Sea is characterized by a scarce background seismicity, while large shocks have struck the northern and southern Adriatic regions in the past. On 27 March 2021 an intraplate Mw5.2 earthquake occurred midway between the Italian coast to the west and the Croatian island of Lastovo to the east. Aftershocks of the 2021 seismic sequence cluster along a WNW-ESE seismic belt in the central basin where a decoupling zone of the northern and southern portions of Adria was proposed (D'Agostino et al. 2008) to accommodate the along strike change in the plate convergence vectors between the European and Adriatic plates. Moreover, if Adria is a separate microplate or a piece of the central Mediterranean puzzle that moves independently of Eurasia and Nubia is still under debate. In this work, we analyze the 2021 seismic sequence by using a multidisciplinary dataset to provide additional constraints on the kinematics of the central Adriatic region.
