Dnica along the deep-seated southeast dipping thrust fault, recognized as a key fault. The co-seismic rupture propagated through the initial half an hour of your Alizarin complexone Protocol earthquake sequence along the thrust towards the northwest, which might be clearly noticed in the time lapse visualization. The location in the principal earthquake from Trakosan c Castle was about 40 km. The principle earthquake was felt using a maximal intensity of VII EMS (Figure three) and was felt all over Croatia, even at a distance of a lot more than 1000 km from the epicenter (see Figure 3 in ). The earthquake hit the city center hardest, along with the initial facts indicated that the damage was meaningful. A variety of damages for the cultural and historical architectural heritage of Zagreb have been reported, with severe harm for the south tower of Zagreb Cathedral. Harm was reported not just inside the city of Zagreb but additionally in the surrounding regions. There was a sizable variety of aftershocks following the key occasion (more than 300 with M1.three inside the subsequent six months ). The mainshock was felt in the Trakosan area c with an intensity of V EMS. 2.two. The Petrinja M6.2 Earthquake in December 2020 On 28 December, 2020, in the early morning hours, a strong M5 earthquake occurred with an epicenter about 6 km SW of Petrinja. The subsequent day, 29 December, just just after noon, a destructive M6.2 earthquake occurred in the exact same location, which, as well as significant damage inside the wider epicentral area, also brought on human casualties. These two earthquakes had been also the strongest within the seismic sequence that took spot in the Petrinja-Pokupsko area. The M5 foreshock proved to have saved numerous human lives, due to the fact it forced quite a few inhabitants to flee their residences. The mainshock occurred at around 90 km in the position of Trakosan Castle. c Reported harm was widespread, with many destroyed or damaged buildings and structures in towns near the epicenter, especially Petrinja and Sisak. Till 31 December, additional than 1300 M1.five aftershocks had been located, including 12 events of magnitudes 4.eight.Geosciences 2021, 11,Geosciences 2021, 11, x FOR PEER Review 5 of5 ofThe larger events added harm to already weakened structures and triggered added collapse. Hundreds of folks, evacuated from their properties, were transferred to makeshift The key earthquake was felt with a maximal intensity of VII EMS (Figure three) and shelters, hotels and also other temporary accommodation inside the wider area. The mainshock was felt all over Croatia, even at a distance of a lot more than 1000 km from the epicenter (see was felt within the Trakosan area with an intensity of V EMS (Figure 4). c Figure three in ).Figure 3.
