Significant impact predicted

The US Geographic Survey (USGS) describes the impact of this earthquake as follows:

One person killed and 52 injured; at least 6 buildings destroyed and 863 damaged in Balkesir. At least 8 homes and 105 buildings damaged at Manisa; a sinkhole was reported in the Odunpazari area.

Based on scientific estimates by the USGS, the risk of high fatalities for this earthquake is classified at level ORANGE (orange). They expect an 47% likelyhood of between 100 and 1,000 fatalities, and a 94% chance that the number of fatalities falls between 10 and 10,000.

The USGS classifies the economic impact of this earthquake at level ORANGE (orange). They expect an 42% likelyhood of between 100 and 1,000 million US Dollars in economic damage and impact, and a 90% chance that the economic impact of this earthquake falls between 10 and 10,000 million USD.

Roughly 34 million people exposed to shaking

This earthquake may have been felt by around 34 million people. That is the expected population size of the area exposed to a level of shaking of II or higher on the Modified Mercalli scale according to the USGS.

Violent shaking and likely heavy damage may have been experienced by an estimated 7,860 people. At IX, it is the highest MMI level this earthquake has caused. Intensity level III was experienced by the majority of people (around 18 million). In their region, weak shaking and probably no damage can be expected.

People in 2 countries have been exposed to shaking. In Türkiye , around 33 million people, with impact levels up to IX (violent shaking, likely heavy damage). People were exposed to shaking in Greece as well.

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Türkiye , Greece and Bulgaria are all within 300km distance of its epicenter.

The closest significant population center near the earthquake is Bigadiç in Balıkesir, Türkiye. Bigadiç is located 10 kilometer (6 mi) west-southwest of the epicenter. The intensity of shaking and damage in Bigadiç is estimated to be around level VIII on the Modified Mercalli Intensity scale (severe shaking, likely moderate to heavy damage).

Major cities near this earthquake: Istanbul is located 199 km to the north-northeast and experienced an intensity of III (weak shaking, probably no damage). İzmir is located 131 km to the southwest and experienced an intensity of IV (light shaking, likely no damage). Bursa is located 128 km to the north-east and experienced an intensity of IV (light shaking, likely no damage).

The table below provides an overview of all places in proximity of today's earthquake. Where available, the estimated intensity on the Modified Mercalli Intensity Scale in each place is included. Places where this information is omitted likely experienced little impact.

Shaking reported by 235 people in 5 countries

People that feel an earthquake may report their experience to the US Geographic Survey. Currently, 235 people have reported shaking in 86 places in 5 countries (Saudi Arabia, Turkey, Bulgaria, Greece, Poland).We keep updating this article as more ground reports become available.

418 Aftershocks detected

After this earthquake struck, 418 smaller aftershocks occurred. A 4.4 magnitude earthquake hit 1 day later 13 km (8 mi) southwest of this earthquake.

In the days before this main shock, 9 smaller foreshocks were detected. Nearby this earthquake a foreshock struck 3 days earlier. It measured a magnitude of 3.9

Overview of foreshocks and aftershocks

More earthquakes coming?

The risk of aftershocks decreases rapidly over time. Usually, aftershocks are at least one order of magnitude lower than a main shock.

In only six percent of cases, significant earthquakes are followed by a larger main shock, making the current earthquake a foreshock. While the chance of this happening is not so large, it is adviced to maintain cautiousness in the hours and days following a major earthquake.

Earthquakes like this are common in the region

Earthquakes of this strength occur quite regularly in the region. This is the strongest earthquake to hit since April 23rd, 2025, when a 6.2 magnitude earthquake hit 163 km (102 mi) further north. An even stronger magnitude 7 earthquake struck on October 30th, 2020.

In total, 4 earthquakes with a magnitude of 6.1 or higher have been registered within 300km (186 mi) of this epicenter in the past 10 years. This comes down to an average of once every 3 years.

Tsunami very unlikely

While MAG-6.5+ earthquakes may cause tsunami's, it appears that the epicenter of this earthquake hit under land. In addition, the reported depth is deeper than 100km, making the risk of a tsunami even less likely. However always stay cautious and monitor advice from local authorities.
