The United States Geological Survey recorded
a Magnitude 5.5 Earthquake at a depth of 62.3 km, about 13 km to the south t of the city of Marmaris in Muğla Province, Turkey, slightly
before 8.45 pm local time
(slightly before 5.45
pm GMT) on Sunday 28 June 2020. No damage or injuries have been
reported following this event, but people have reported feeling the
event across southwest Turkey as well as on the island of Rhodes.

Muğla Province lies on 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.

Witness
accounts of Earthquakes can help geologists to understand these events,
and the structures that cause them. The international non-profit
organisation Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here.
