TL;DR: The Marnaut cruise in the Sea of Marmara as discussed by the authors investigated the pore fluid chemistry of sites along the Main MarmARA Fault Zone and determined the sources and evolution of the fluids.

TL;DR: In this article, the authors investigated the submerged section of the North Anatolian fault within the Marmara Sea using acoustic techniques and submersible dives and found that most gas emissions in the water column were found near the surface expression of known active faults, and this zone of gas emission extends westward all along the southern edge of Cinarcik basin, well beyond the zone where 1999 aftershocks were observed.

TL;DR: Observations suggest that SSEs and associated slow earthquake phenomena are promoted by lithological, mechanical, and frictional heterogeneity within the fault zone, enhanced by geometric complexity associated with subduction of rough crust.

TL;DR: The early Plio-Pleistocene Corinth rift is preserved in the northern Peloponnese peninsula, south of the active Corinth rift as discussed by the authors, and new structural, stratigraphic and sedimentological data for an area >400 km2 record early rift evolution in three phases separated by distinct episodes of extension rate acceleration and northward fault migration associated with major erosion.

TL;DR: Evidence of sediment dehydration was found which increased fault strength and allowed for the much larger earthquake to occur, suggesting that models of other subduction zones, such as the Gulf of Alaska, may underestimate the maximum earthquake magnitude and tsunami risk.
