M 4.3 in western Turkey

 

A M4.3 quake shook western Turkey today. This event lies near the eastern tip of the 1912 M7.4 Ganos earthquake rupture area, a site perhaps brought closer to failure by that event.
 

 

Today’s quake lies between extensional and strike-slip faults mapped by Armijo et al. (2002), at the edge of the Marmara basin, a pull-apart structure resulting from a right step in the North Anatolian Fault Zone.
