Two tremors measuring 2.3 and 2.2 on the Richter scale were registered in the hinterland of the northern coastal town of Crikvenica on Saturday evening, the Croatian Seismological Service stated.

A series of tremors of smaller intensity have been registered in Croatia since 22 March when a 5.5-strong quake hit Zagreb and its environs, taking one life and causing extensive damage.

The Seismological Service says that since that strong earthquake, about 145 tremors have been felt across the country. In addition, 850 tremors weaker than 1.3 have also been registered to date.

Croatia’s seismologically most active areas are a wider Zagreb area, southern Dalmatia and a wider Rijeka area.
