Regional coverage
This page groups Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, Romania, Serbia and Slovenia, with selected Adriatic activity. Greece and Turkey have separate regional maps. These monitoring areas are practical groupings rather than a fixed definition of the Balkan Peninsula, and coverage near borders depends on the event location and catalogue description.

About Earthquakes in the Balkans

The Balkans are a connected earthquake region with very different kinds of activity. Along the Adriatic coast, compression helps build mountains and drives faults beneath coastal towns. Farther inland, faults can slide sideways or stretch the crust. In Romania’s Vrancea zone, earthquakes begin much deeper underground and can send shaking across several countries.

That variety matters. An earthquake near Petrinja in Croatia is not the same kind of event as a deep Vrancea earthquake, even if the magnitudes look similar on a list. The depth, direction of fault movement and ground beneath a town all influence what people experience. Our broader Europe earthquake map places these different Balkan settings alongside the Mediterranean and the rest of the continent.

The region’s earthquake history also challenges the idea that only enormous earthquakes cause serious damage. Skopje, Zagreb, Durrës and Petrinja show what can happen when shallow earthquakes occur close to buildings and communities. The consequences depend on much more than the largest number on the map.

Why the Ground Is Still Moving

The western Balkans sit along the eastern side of the Adriatic region, often described in tectonic studies as Adria. Its movement relative to the rest of Europe contributes to shortening and faulting along the Dinarides, the mountain belt running through much of the western region. The wider forces ultimately form part of the complex interaction between Africa and Eurasia.

There is no single continuous “Balkan fault” responsible for everything. Deformation is spread across many faults, and the pattern changes from the coast to the interior. Research into active tectonics in Croatia’s Kvarner region describes the interaction of Adria with the External Dinarides and shows why detailed local geology matters when identifying earthquake sources.

Along parts of Albania and Montenegro, compression produces thrust earthquakes, where one side of a fault moves up over the other. Elsewhere, sideways movement and extension are important. The USGS analysis of the 2019 Albania earthquake identifies thrust faulting, while the 2020 Petrinja earthquake involved a very different fault setting in inland Croatia. Neither event can be understood by treating the whole peninsula as one uniform block.

Where Earthquakes Occur Across the Region

The Adriatic Coast and Dinaric Mountains

Coastal Croatia, Montenegro, Albania and the neighbouring mountain belts contain important earthquake sources both on land and offshore. A rupture does not have to sit directly beneath a town to damage it, and the nearest town named in a catalogue may be some distance from the actual fault. Steep slopes, narrow valleys and coastal transport routes can add landslide and access problems to the effects of shaking.

The 1979 Montenegro earthquake is a lasting example. It damaged settlements and historic buildings along the coast, including Kotor. UNESCO’s account of the Kotor World Heritage region describes serious damage to churches and town walls, followed by extensive restoration. Here, earthquake recovery involved protecting a living town and its cultural heritage together.

Croatia, Slovenia and the Inland Northwest

Earthquake activity continues inland through Croatia and Slovenia, where the Dinaric, Alpine and Pannonian regions meet. Zagreb and the Petrinja area demonstrate that damaging earthquakes are not confined to the tourist coast. The surrounding fault systems differ in orientation and movement, so two nearby sequences need not be caused by the same fault.

After the Petrinja earthquake, researchers installed additional instruments to improve the location of smaller earthquakes and their depths. The University of Zagreb’s Petrinja-Net project explains how a denser temporary network sharpened the picture of the sequence. It is also a useful reminder that an increase in recorded small events can partly reflect better monitoring.

Bosnia and Herzegovina, Serbia, Kosovo and North Macedonia

The inland Balkans contain active faults and basins that can produce damaging shallow earthquakes. Activity around places such as Banja Luka, southern Herzegovina, central Serbia and the Skopje basin belongs to this wider picture. Distance from the Adriatic shoreline is no assurance that a town is beyond earthquake hazard.

The 2022 earthquake near Stolac illustrates another problem in mountainous terrain. In addition to damage to buildings, rockfalls and falling debris can create danger away from the fault itself. Local effects can differ sharply between a valley floor, a hillside and a nearby rock outcrop, even when all three places are close together.

Bulgaria’s Active Basins and Faults

Bulgaria has its own shallow earthquake sources, including the Struma valley, the Sofia area and the Upper Thracian Plain around Chirpan and Plovdiv. It can also experience shaking from earthquakes outside its borders, particularly larger Vrancea events in Romania. Local earthquakes and distant deep earthquakes therefore need to be considered separately.

The destructive 1928 Chirpan–Plovdiv sequence left surface evidence that scientists can still investigate. A study of the Chirpan fault rupture examines the normal fault responsible for the 14 April event. These studies use fault scarps and displaced ground to extend understanding beyond the short period covered by modern instruments.

Romania and the Vrancea Zone

Vrancea, near the bend of the Carpathians, is the major exception to the region’s mostly shallow earthquake picture. Important earthquakes originate at intermediate depths, well below the upper crust. Their waves can be felt far beyond Romania, which is why a Balkan earthquake list can include an event whose effects span several national borders.

Depth does not remove the danger. The 1977 Vrancea earthquake caused severe damage in Bucharest, well away from the epicentre. Romania also has shallow earthquake sources, as the 2023 Gorj sequence demonstrated. Romania’s National Institute for Earth Physics describes the national network that monitors these different seismic regions.

What Makes an Earthquake Damaging Here

Shallow Ruptures and Vulnerable Buildings

Many damaging Balkan earthquakes start in the upper crust, close enough to settlements to produce intense local shaking. Older masonry buildings, weak connections between walls and floors, heavy roofs and poorly detailed concrete structures can increase vulnerability. Historic centres can be particularly difficult to strengthen because repairs must respect both structural safety and heritage.

The 2019 Albania earthquake showed that recovery extends beyond clearing rubble. Homes, schools and health services all need to function again. The World Health Organization’s account of the response describes the need to maintain care for injuries and ongoing medical conditions after the disaster.

Soft Ground, Basins and Slopes

Loose sediments and sediment-filled basins can change the strength and duration of shaking compared with nearby bedrock. Under suitable conditions, saturated loose ground can also lose strength through liquefaction. Steep or fractured slopes introduce rockfall and landslide hazards, especially where roads pass beneath cliffs or through narrow valleys.

This is why earthquake magnitude is only part of the picture. A larger earthquake is not automatically more damaging at your location than a smaller, shallower one nearby. Depth, distance, local ground and building design all help explain the difference.

What the earthquake numbers mean

• Below M3 Often not felt, although very shallow events can be noticeable nearby.
• M3–4.9 May be felt locally. Effects depend strongly on proximity and building vulnerability.
• M5–5.9 Can cause damaging shaking near populated areas, particularly when shallow.
• M6–6.9 Can cause serious damage and disruption over an affected region.
• M7 and above Can produce widespread consequences, but damage still depends on the source, ground conditions and exposed communities.

These are broad guides, not fixed damage thresholds. The same earthquake produces different shaking at different places.

The Adriatic Has Tsunami Hazard Too

The Adriatic is not exempt from tsunamis, but an offshore earthquake marker is not itself a warning. A tsunami depends on how water is displaced, including the size, depth and mechanism of a rupture and any associated underwater landslide. Many offshore earthquakes do not generate a damaging tsunami.

The UNESCO-IOC system for the North-Eastern Atlantic, Mediterranean and connected seas provides the framework for regional tsunami warning cooperation. For a person on the coast, strong or prolonged shaking and unusual sea behaviour are reasons to follow local evacuation guidance. This earthquake map is not a tsunami alert service.

Earthquakes That Left a Lasting Mark on the Balkans

These events show the range of Balkan earthquake hazards, from shallow urban disasters to deep earthquakes felt across borders. The list is selective rather than a catalogue of every damaging event. Older magnitudes are reconstructed, and different agencies may use different magnitude scales for the same earthquake.

• 1895 Ljubljana earthquake, estimated Mw6.1
  The earthquake of 14 April damaged Ljubljana and helped shape the city’s subsequent rebuilding and earthquake research. Research revisiting the earthquake’s source uses historical intensity observations, while the National Museum of Slovenia’s photographs preserve a view of the damage. Its magnitude is an estimate derived long after the event, not a modern instrumental measurement.
• 1928 Chirpan–Plovdiv sequence, Bulgaria
  Destructive earthquakes on 14 and 18 April affected the Upper Thracian Plain, damaging towns and villages and rupturing faults at the surface. Published magnitude estimates vary by study and scale. The investigation of the Chirpan rupture shows why evidence preserved in the landscape remains important for assessing future hazard.
• 1963 Skopje earthquake, North Macedonia
  The 26 July earthquake devastated much of Skopje and led to a major international relief and reconstruction effort. The Red Cross of North Macedonia’s anniversary account records widespread destruction of housing. Its lasting importance lies in the impact of a shallow earthquake beneath an urban area and the rebuilding effort that followed.
• 1977 Vrancea earthquake, Mw7.4
  On 4 March, a deep earthquake beneath the Carpathian bend caused catastrophic damage in Bucharest and was felt far beyond Romania. The published macroseismic dataset lists Mw7.4 and a depth of 98 km. It remains a defining example of a damaging intermediate-depth earthquake whose consequences extended well beyond its epicentral area.
• 1979 Montenegro coastal earthquake, about M7
  The 15 April earthquake caused extensive coastal destruction and damaged historic settlements. UNESCO documents the damage and restoration in Kotor, where churches, walls and other monuments were affected. The event remains central to understanding coastal earthquake risk in the region.
• 2019 Albania earthquake, Mw6.4
  On 26 November, an earthquake near the Durrës region caused building collapses, with Durrës and Thumanë among the worst-affected places. The USGS event record gives M6.4, and WHO reported 51 deaths. The disaster exposed the consequences of vulnerable buildings and the difficulty of maintaining essential services during recovery.
• 2020 Zagreb earthquake, ML5.5
  The 22 March earthquake damaged buildings in Croatia’s capital, including its historic centre. The Croatian Seismological Survey’s anniversary account reports local magnitude 5.5. That is a different scale from moment magnitude, which explains why other reports may show a somewhat different number.
• 2020 Petrinja earthquake, Mw6.4
  On 29 December, a destructive earthquake struck near Petrinja in central Croatia. The University of Zagreb gives ML6.2 and Mw6.4 for the same event. Its aftershock sequence and subsequent monitoring work made it an important modern case study of inland Balkan faulting, beyond the better-known Adriatic coastal belt.
• 2022 Stolac earthquake, Bosnia and Herzegovina, Mw5.7
  The 22 April earthquake caused damage and a fatality in southern Bosnia and Herzegovina. The British Geological Survey event summary records the death and widespread felt reports, while the Federal Civil Protection Administration documented rockfalls on several roads. It illustrates how falling rocks and debris can add to the danger from shaking.
• 2023 Gorj sequence, Romania, ML5.2 and ML5.7
  Earthquakes on 13 and 14 February were followed by a prolonged sequence in the Southern Carpathians. The researchers’ published Gorj dataset contains the two principal events and thousands of located aftershocks. Its significance is the contrast with Vrancea, reminding us that Romanian earthquake hazard also includes shallow crustal sources.

Earthquake Preparedness

You do not need to know the name of the nearest fault to prepare sensibly. Start with what could fall, where you would take shelter and how you would contact people afterwards. If you are travelling, check your accommodation’s evacuation plan and learn which local authority provides emergency instructions. Greece’s Civil Protection guidance gives practical advice relevant to the wider region, while local instructions should guide any response where you are staying.

During and After the Shaking

Drop, Cover and Hold On. If you are indoors, get low, take cover beneath a sturdy table where possible and protect your head and neck. Hold on until the shaking stops. Stay away from windows and heavy furniture. Do not rush outside or use a lift during the shaking, because falling glass, masonry and other debris can make exits dangerous.

If you are already outdoors, keep away from buildings, walls, power lines and unstable slopes. Afterwards, expect aftershocks and do not enter damaged structures until they have been assessed. In older town centres, a building can shed roof tiles, chimneys or stonework even where the main walls remain standing.

A Practical Safety Checklist

• Secure tall furniture and keep heavy objects away from beds and seating areas.
• Keep water, food, medication, a torch, a first aid kit and a charged power bank accessible.
• Agree on a meeting place and a contact outside the affected area.
• Check the emergency arrangements at your home, workplace or holiday accommodation.
• Near the coast, learn local tsunami evacuation routes and move inland or uphill after strong or prolonged shaking.
• In mountain areas, watch for rockfalls, damaged roads and blocked routes after an earthquake.
• Use official civil-protection information rather than rumours or predictions circulating online.

Our Earthquake Safety guide explains protective actions during shaking, and the Earthquake Preparedness guide covers supplies and planning.

Did you know?
ML6.2 and Mw6.4 can describe the same earthquake. The University of Zagreb reports both values for the 2020 Petrinja earthquake because local magnitude and moment magnitude measure earthquake size in different ways. A difference between those figures is not evidence of two separate events.

How Earthquakes Are Monitored Across the Balkans

National networks locate earthquakes using stations on both sides of borders, while regional organisations help share information. Local services can detect far more small earthquakes than a global catalogue publishes. That is why an event may appear on a national agency’s map before it appears here, or may not enter the USGS catalogue at all.

• Croatian Seismological Survey Based at the University of Zagreb, it monitors Croatian earthquakes and publishes event information and analyses.
• Seismological Survey of Serbia: Publishes information on earthquakes in Serbia and surrounding regions, distinguishing preliminary automatic results from processed information.
• NIGGG at the Bulgarian Academy of Sciences provides earthquake monitoring information for Bulgaria and neighbouring seismic zones.
• Romania’s National Institute for Earth Physics monitors Vrancea and Romania’s other seismic sources and maintains national earthquake data.
• The Seismological Observatory in Skopje provides national seismological expertise within Ss. Cyril and Methodius University.
• European-Mediterranean Seismological Centre Combines information from contributing institutes with eyewitness reports to describe earthquakes across the wider region.
• ORFEUS supports access to European seismic recordings and related research infrastructure.

The live list, map and statistics on this page use USGS data through a shared regional dataset. The organisations linked above provide additional context rather than separate feeds added to this map. Earthquake parameters may change as more observations are reviewed, and clusters of small earthquakes do not reliably predict the timing or size of a future large event.
