At 12:19 PM CET (11:19 UTC) on 29 December 2020, an earthquake of magnitude 6.4 Шаблон:M (6.2 Шаблон:M) hit central Croatia, with an epicenter located roughly Шаблон:Cvt west-southwest of Petrinja. The maximum felt intensity was estimated at VIII (Heavily damaging) to IX (Destructive) on the European macroseismic scale. Before this event there were three foreshocks, the strongest of which had a magnitude of 5.2 Шаблон:M on the day before. The earthquake was followed by numerous aftershocks, the strongest of which had a magnitude of 4.9 Шаблон:M. The adversely affected areas were mostly in the Sisak-Moslavina County and other nearby Croatian counties, as well as some of the nearby areas of Bosnia and Slovenia.Шаблон:Citation needed

Seven people were confirmed dead, while 26 others were injured, with six having serious injuries. Initial reports show many buildings destroyed in Petrinja. The mayor of Petrinja, Darinko Dumbović, said that half of the town has been destroyed.

The first multidisciplinary scientific paper on Petrinja 2020 earthquake was published in Remote Sensing journal in March 2021.Шаблон:Primary source inline

Tectonic setting

The epicenter is located in a hilly area just south of the Kupa-Sava alluvial plain, with the Zrinska gora mountain and the rest of the Dinaric Alps to the south.

The Pokuplje seismic area follows the Kupa river valley from Karlovac to Sisak. This area has been affected by several historical earthquakes, the best known being the major event in 1909 with the epicenter near Pokupsko, with aftershocks that continued into 1910. It had a maximum felt intensity of VIII on the MCS scale. This seismicity has been associated with reactivation of northwest–southeast trending normal faults that form the southwestern boundary of the Pannonian Basin.

The last earthquake on the territory of Croatia that had a magnitude of 6.0 Шаблон:M was in Ston in 1996. In 1969, the fault system which extends from Jastrebarsko over this area towards Banja Luka had a 6.6 Шаблон:M earthquake which hit the latter city, and that one was also preceded by significant foreshocks one day earlier. In 1880, a 6.3 Шаблон:M struck north-east of Zagreb. In March 2020, a 5.5 Шаблон:M earthquake struck the city of Zagreb.

Earthquake

The earthquake had a magnitude of 6.4 Шаблон:M and a depth of Шаблон:Convert according to Advanced National Seismic System (ANSS) and European-Mediterranean Seismological Centre (EMSC), while the Seismological Survey of Croatia recorded 6.2 Шаблон:M. The maximum felt intensity was VIII (heavily damaging) to IX (destructive) on the European macroseismic scale (EMS) and IX (Violent) on the Modified Mercalli intensity scale (MMI).

The location and depth of this event show that it was an intraplate earthquake that occurred as a result of shallow strike-slip faulting within the Eurasian Plate. The calculated focal mechanism for the event indicates that rupture occurred on a nearly vertical fault striking either to the southeast or southwest.

The Croatian Seismological Survey estimated the earthquake's epicentre at Шаблон:Coord (45.4002, 16.2187), located near the village of Strašnik, within the town of Petrinja.

The earthquake was felt throughout northern Croatia, as well as in large parts of Slovenia, Austria, Bosnia and Herzegovina, Serbia, Hungary, Slovakia, and Italy, as well as in some parts of Montenegro, Germany, and the Czech Republic.Шаблон:Better source needed

Damage

The town of Petrinja was the worst affected, with many buildings collapsed and a major power outage. Damage and power outages were also reported in Dvor, Glina, Gvozd, Hrvatska Kostajnica, Kutina, Sisak, Sunja, Topusko, Velika Gorica, and Zagreb, as well as the neighbouring countries Bosnia and Herzegovina and Slovenia.

The total damage was estimated by World Bank consultants in cooperation with the Ministry of Construction and the Ministry of Regional Development and EU Funds. The total damage is estimated at 5 billion euros and may eventually increase to 5.5 billion euros.

Sisak-Moslavina County

In Petrinja, the town closest to the epicenter, almost all houses were damaged. The whole town centre was heavily damaged. One elementary school was damaged. Roofs of the town hall and the Church of Saint Lawrence were destroyed. The entire village of Brest Pokupski near Petrinja was heavily damaged.

The city of Sisak, located roughly Шаблон:Convert northeast of the epicenter, suffered major damage to its hospital, as well as its city hall. Despite the damage, the hospital was not shut down. Most damage was inflicted on old buildings in the center of the town. It is estimated that between 700 and 1,000 houses were damaged in Sisak and nearby villages.

In the village of Strašnik where the epicenter was located, as well as in the nearby village of Sibić, almost all houses were damaged. Part of the villages' populations were evacuated and tents with food and water were set up.

Majske Poljane is the village that suffered the most damage from the earthquake; all buildings were damaged and many collapsed. It is also the place with the largest number of deaths, out of seven total fatalities five were in Majske Poljane.

In Žažina, one church collapsed, injuring three and killing one other person.

Cover collapse sinkholes have started appearing since the earthquake near the villages of Mečenčani and Borojevići. As of March 2021, there were over 90 of them, some endangering homes. The largest hole was Шаблон:Convert deep and Шаблон:Cvt in diameter. While this area lies on karstic bedrock covered by a layer of proluvial soil and is ordinarily prone to occasional sinkholes, the quantity, size and location of the sinkholes has prompted the authorities to consider evacuating the villages. According to the geophysicists, the earthquake likely disrupted the underground water currents, accelerating the natural karstification. State company Hrvatske vode began remedying the sinkholes, but as of December 2021, new sinkholes were still appearing.

Zagreb County and City of Zagreb

In Pokupsko, which is roughly Шаблон:Convert northwest of the epicenter, many buildings were damaged including a school, a kindergarten and an 18th-century church.

In the town of Zaprešić, which is roughly Шаблон:Convert north-northwest of the epicenter, four residential buildings sustained damage, forcing more than 80 families to leave the town.

The city of Zagreb, which is roughly Шаблон:Convert to the north of the epicenter, was affected with some building damage, power outages, and many residents taking to the streets in distress.

Bosnia and Herzegovina

Buildings were damaged in multiple towns across northwestern Bosnia and Herzegovina, in the Una-Sana Canton and northern Republika Srpska, which are roughly between Шаблон:Convert and Шаблон:Convert southwest, south, and southeast of the epicenter. Towns which were damaged include Velika Kladuša, Bihać, Cazin, Kozarska Dubica, and Kostajnica, which suffered the most damage from the earthquake. In Kostajnica, a state of emergency was declared, the earthquake caused six conflagrations, and many buildings were damaged, including the town hall, which was declared out of function.

Slovenia

Buildings were damaged in several areas and towns, mostly near the Slovenia–Croatia border. People reported damage to facades, roofs, and chimneys from the southeastern towns of Krško and Brežice and the old town of Kostanjevica na Krki, which lie roughly Шаблон:Convert northwest of the epicenter. The Krško Nuclear Plant automatically shut down and was later systematically reviewed, with no damage reported. In northeastern Slovenia, roughly Шаблон:Convert north-northwest of the epicenter, there were power and telecommunication outages in the area of its central town of Maribor, the municipal building in nearby Ptuj was damaged, and there was damage to the church in Sveta Trojica. In Ljubljana, the capital, a session of Parliament had to be stopped, and the interior of the Parliament building incurred minor damage. No injuries were recorded in the country.

Hungary

The quake was also felt strongly in many parts of Hungary. However, there was only limited damage recorded. In an old house in Egervár, small cracks appeared and plaster fell. In counties such as Baranya, Zala, Somogy and Tolna, damage consisted of fallen plaster, cracked walls and ceilings, broken windows and, toppled chimneys. Damage in the country is said to have exceeded 100 million forints.

Austria

The quake was felt throughout Austria. Like in Hungary, limited damage was also observed, mostly in the form of cracks on walls and plaster. In Austria, the quake was felt with a maximum intensity of IV (Largely observed) to V (Strong) on the European macroseismic scale.

Italy

Like with other countries, damage in Italy was limited, but in Trieste, near the border with Slovenia and Croatia, some buildings cracked.
