Magnitude 6.0 Earthquake in Balıkesir Province, Turkey.

The United States Geological Survey recorded a Magnitude 6.0 Earthquake at a depth of 8.0 km, about 4 km to the southeast of the municipality of Sındırgı in Balıkesir Province, Turkey,  slightly before 10.,50 pm local time (slightly before 7.50 pm GMT) on Monday 27 October 2025. No casualties have been reported following this event, but several buildings damaged during another Earthquake in August are reported to have collapsed. The Earthquake was felt across western Turkey, and in parts of southern Bulgaria.

Balıkesir Province lies close to the boundary between the Anatolian Plate, to the north, the Aegean Sea Plate (underlying the Peloponnese, Attica, The Cyclades Islands, Crete, the Dodecanese Islands and Turkey to the southeast of the Taurus Mountains) to the west and the African Plate to the south. Northern Greece and the north coast of Turkey lie on the Eurasian Plate. Both countries are highly prone to earthquakes because of this.

To the east the Arabian Plate  is being pushed north and west by the movement of the African Plate, further to the south. This leads to a zone of tectonic activity within the province, as the Arabian and Anatolian plates are pushed together, along the East Anatolian Fault, and past one-another, along the Dead Sea Transform.

This movement also leads to a zone of faulting along the northern part of Turkey, the North Anatolian Fault Zone, as the Anatolian Plate is pushed past the Eurasian Plate, which underlies the Black Sea and Crimean Peninsula  (transform faulting). This is not a simple process, as the two plates constantly stick together, then break apart as the pressure builds up, leading to Earthquakes, which can be some distance from the actual fault zone.

Archaeologists uncover seventh century iron sabre at tomb in Hungary.

Archaeologists from the Hungarian National Museum in Budapest and the Szent István Király Museum in Székesfehérvár have uncovered a rare seventh century iron cavalry sabre, among other grave goods, while excavating what is believed to be the tomb of an Avar warrior. The tomb, which is near Székesfehérvár, was detected in satellite images by the 'Cemeteries from Space' program, a collaboration between several Hungarian museums which uses satellite and other remote sensing images to look for signs of ancient activity in croplands and other areas where they might not be obvious to people standing on the ground.

The tomb is thought to have dated to between 670 and 690, and had been partially looted, but still contained grave goods including the sword, some silver belt fittings, gilded metal ornaments for braiding into hair, earrings made from glass beads, a long knife, and arrowheads. Other artefacts likely to have been present, such as the shafts of the arrows, and a leather belt for the silver fittings, and probably a leather quiver for the arrows, had decayed away. The skeleton of the warrior appears to have been damaged during the looting process, particularly around the chest area.

The Pannonian Avars occupied a large area of Central Europe during the sixth to ninth centuries, forming a state known as the Avar Khaganate, which at its peak stretched from Czechia to eastern Ukraine. Unfortunately, most of what we know about the Avars today comes from Byzantine sources, a civilisation with which their relations were not always good. Byzantine records suggest that they had migrated from Central Asia, and were probably related to the nomadic Avars of that region. They may have had a Turkic or Mongolian ruling class, or have fled Central Asia to avoid domination by such a group. Genetic studies of remains from Avar graves in Europe have confirmed a genetic relationship to the Avars of Central Asia, with both groups originating in northeast Asia. However, they were not related to the Avars of the Caucasus Region, who appear to have been a separate group. Such studies have also suggested that women left their parents households to join those of their husbands, which would imply a patrilineal society.  From the middle of the eighth century the Pannonian Avars began to lose territory in the west to the expanding Frankish Kingdom, with chiefdoms incorporated into that state being Christianised and losing their cultural distinctiveness. From the beginning of the ninth century, invading Bulgars from the east also began to seize territory from the Pannonians, eventually leading to the end of the Khaganate as a distinct political entity.
