Significant impact predicted

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

At least 26 persons injured, five buildings destroyed and at least 80 buildings damaged in Sindirgi. At least 42 persons injured and 83 buildings damaged in Manisa.

Based on scientific estimates by the USGS, the risk of high fatalities for this earthquake is classified at level YELLOW (significant). They expect an 46% likelyhood of between 1 and 10 fatalities, and a 95% chance that the number of fatalities falls no higher than 100.

The USGS classifies the economic impact of this earthquake at level YELLOW (significant). They expect an 43% likelyhood of between 10 and 100 million US Dollars in economic damage and impact, and a 92% chance that the economic impact of this earthquake falls between 1 and 1,000 million USD.

Roughly 23 million people exposed to shaking

An estimated 23 million have been exposed to shaking (An MMI or Modified Mercalli Intensity level II or higher) as a result of this earthquake according scientific estimates published by the USGS.

The highest earthquake impact level for this earthquake is VIII, which corresponds with severe shaking and likely moderate to heavy damage. Roughly 4,870 people are expected to be exposed to this level. Intensity level IV was experienced by the majority of people (around 12 million). In their region, light shaking and likely no damage can be expected.

People in 2 countries have been exposed to shaking. In Türkiye , around 23 million people, with impact levels up to VIII (severe shaking, likely moderate to heavy damage). People were exposed to shaking in Greece as well.

Nearby towns and cities

This earthquake struck within proximity of multiple countries. Türkiye and Greece are both within 300km distance of its epicenter. Futher away, this earthquake may also have been felt in Bulgaria.

The closest significant population center near the earthquake is Bigadiç in Balıkesir, Türkiye. Bigadiç is located 24 kilometer (15 mi) south-southeast of the epicenter. The intensity of shaking and damage in Bigadiç is estimated to be around level VI on the Modified Mercalli Intensity scale (strong shaking, probably light damage).

Major cities near this earthquake: Istanbul is located 211 km to the north-northeast (intensity unknown, possibly low). İzmir is located 130 km to the southwest and experienced an intensity of IV (light shaking, likely no damage). Bursa is located 131 km to the north-northeast 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.

290 Aftershocks detected

Since this main shock, 290 smaller aftershocks were detected. A 4.9 magnitude earthquake hit 12 hrs later 10 km (6 mi) north-east of this earthquake.

In the days before this main shock, 11 smaller foreshocks were detected. A 3.7 magnitude earthquake hit 3 days earlier nearby.

Overview of foreshocks and aftershocks

More earthquakes coming?

Aftershocks are usually at least 1 order of magnitude less strong than main shocks. The more time passes, the smaller the chance and likely strength of any potential aftershocks.

It's always adviced to be cautious of the risk of a larger shock following any significant earthquake, however this risk is fairly small. There is a roughly 94 percent change that no larger main shock will follow in the days following this 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 August 10th, 2025, when a 6.1 magnitude earthquake hit 28 km (17 mi) further northwest. An even stronger magnitude 7 earthquake struck on October 30th, 2020.

In total, 6 earthquakes with a magnitude of 6 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 2 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.
