Sažetak

The December 2020 sequence of earthquakes in Croatia started on 28 December 2020 at 6:28 local time, with a magnitude M5.0 with epicenter near Petrinja. It was followed with a M4.7 at 7:49 and a M4.1 at 7:51, with a series of weaker aftershocks. On 29 December 2020 at 12:19, a M6.4 struck, which was felt in all parts of Croatia and neighboring countries. The sequence continued for 36 days (Croatian Seismological Survey 2021). The most prominent, surprising, and relatively rare geotechnical earthquake effect includes the collapse of numerous sinkholes in the time frame of three months after the main shock.
