Turkey quake to cause small tsunami: EMSC
A 6.7-magnitude earthquake off the southwestern coast of Turkey could cause a small tsunami in the area, European quake agency EMSC said, although Turkish officials said large waves were more likely than a tsunami....From the U.S. Geological Service via the New Straits Times:
The epicenter is just offshore southwestern Turkey while the 'big one' is expected in Istanbul's backyard.
As the Daily Sabah reminds us:
... Turkey is among one of the world's most seismically active countries as it is situated on a number of active fault lines, with the most potentially devastating one being the Northern Anatolia Fault (NAF), where the Anatolian and Eurasian plates meet.For which see: May 20's "Risk: Massive Earthquake Could Hit Istanbul at any Moment with just SECONDS Warning, Say Scientists".
The NAF, a strike-slip fault formed as the Anatolian plate was being pushed northwestwards by the Arabian plate, has produced devastating earthquakes throughout history, with the most recent ones being magnitude 7.4 and 7.2 earthquakes in northwestern Izmit and Düzce provinces in August and December 1999. The 1999 earthquakes killed thousands in Kocaeli, Adapazarı, Istanbul, Yalova and nearby towns in the northwest, which serve as Turkey's economic and industrial heartland....
...Scientists have warned that the epicenter of Turkey's next big earthquake is likely to occur under the Sea of Marmara, where the NAF passes.
