In 1999 the North Anatolian Fault (NAF), Turkey, broke during two destructive #earthquakes east of Istanbul (Mw7.4 Izmit and Mw7.2 Düzce earthquakes respectively on 17 Aug and 12 Nov).
Today's Mw6.1 #earthquake happened just east of Düzce with a faulting mechanism very similar to the 12 Nov 1999 event (strike-slip with small normal component). Its epicenter is located little to the north of the main NAF fault trace.

@RobinLacassin Has there been an increase in seismic activity this year? It seems busy.
So no correlation, I'm programming algorithms all day so I look for correlations in everything 🙄🙂. I'm a seismology noob, but learning fast and loving it. Last night I was studying how reflections in shockwaves off of the mantle can combine and increase the force, and also react with different surface types like sand, limestone, clay. It's incredibly fascinating.
Maybe one day after I've learned enough about the mechanics. I can start applying algorithms to extrapolate correlations to the data. That would be pretty cool. Got any good books you can recommend?
@skanman Just to start I would recommend the books by Susan Hough:
• Predicting the Unpredictable: The Tumultuous Science of Earthquake Prediction
• Earthshaking Science: What We Know (and Don't Know) about Earthquakes
