Gas and seismicity within the Istanbul seismic gap
Abstract Understanding micro-seismicity is a critical question for earthquake hazard assessment. Since the devastating earthquakes of Izmit and Duzce in 1999, the seismicity along the submerged section of North Anatolian Fault within the Sea of Marmara (comprising the “Istanbul seismic gap”) has bee...

Abstract Understanding micro-seismicity is a critical question for earthquake hazard assessment.
