The victims of the 1999 Marmara earthquake, the most devastating earthquake in the history of modern Turkey, were remembered on Aug. 17, as concerns over a potential disaster of a similar magnitude that is expected to hit Turkey continue to mount.

An earthquake of magnitude 7.2 has struck the Alaska Peninsula, the U.S. Geological Survey (USGS) said late on Wednesday.

The quake was at a depth of 35 km, USGS added.

The U.S. Tsunami Warning System, which said the quake had a magnitude of 8.1, issued a tsunami warning for the U.S. Pacific territories of Guam and the Northern Mariana Islands.

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.

Scientists say it is a normal magnitude for this region

What seismologists agree on is that it is an unusual phenomenon to record small earthquakes in a short period of time

A magnitude-5.3 earthquake struck Turkey's southwestern province of Muğla, the country's disaster agency said early on June 22. 

The Disaster and Emergency Management Authority (AFAD) said the quake struck 11.4 kilometers (7.08 miles) below the surface of the Aegean Sea, 40 kilometers (24.8 miles) off the coast of Datca district.

A magnitude-4.0 earthquake struck Turkey's western Balıkesir province, the country's disaster agency said early on April 22. 

The Disaster and Emergency Management Authority (AFAD) said the quake struck 7 kilometers (4.34 miles) below the surface in Sındırgı district.

Turkey is crossed by fault lines and is prone to earthquakes. 

An earthquake with a magnitude of 3,5 on the Richter scale and at a depth of 13 kilometers was registered on the territory of Blagoevgrad region (southwestern Bulgaria) this night at 02:31 am, reported the National Institute of Geophysics, Geodesy and Geography of the Bulgarian Academy of Sciences.
