The Disaster and Emergency Management Authority (AFAD) said the first quake, with a magnitude of 4.3, was recorded off the coast of the town of Datça in Muğla province at 2 a.m. local time (0000GMT).

Greenland's ice sheet has experienced a "massive melting event" during a heatwave that has seen temperatures more than 10 degrees above seasonal norms, according to Danish researchers. 

A new earthquake measuring 5.4 on the Richter scale was recorded at 07:31 in the sea off Nisyros, according to an announcement published by the Geodynamic Institute of the National Observatory of Athens, which characterizes the earthquake as "strong".

The epicenter was reported 23 kilometers south-southwest of Nisyros, at a depth of 15.6 kilometers.

A fault line formed on the coast of Hatay's Arsuz district due to a magnitude 6.2 earthquake shaking Adana's Ceyhan district in 1998 has become the home of sea creatures.

The fault line, which is approximately a kilometer long, acts as a natural reef 13 to 18 meters below the sea and 15 to 20 meters from the coast.

A report presented to parliament called for attention to the threat of tsunamis in the Marmara Sea in the event of a possible major earthquake expected in Turkey's northwestern region.

Drafted by a parliamentary subcommittee investigating earthquake risks, the report underlined that Turkey is susceptible to tsunamis due to the high seismic activity under the sea.

An earthquake with a magnitude of 4.2 was recorded in Turkey's southern Osmaniye province, the country's disaster agency reported early on July 26. 

The Disaster and Emergency Management Authority (AFAD) said the quake occurred in Düziçi district seven kilometers (4.3 miles) below the surface.

The weather in Bulgaria on Friday will be sunny. In the eastern half of the country there will be moderate winds from north-northeast. Temperatures will rise and daytime highs will be between 27 °C and 32 °C.
