TL;DR: Weimer et al. as discussed by the authors showed that 30% of the World's population lives within 60 km of the coast, and the hazard posed by submarine landslides is expected to grow as global sea level rises.

TL;DR: It is argued that diatom blooms observed by remote sensing facilitated rapid deposition of 134Cs to hadal environment and the aftershocks induced successive sediment disturbances and maintained dense nepheloid layers in the trench even four months after the mainshock.

TL;DR: The first real-time record of a turbidity current associated with a great earthquake, the Mw 9.0, 2011 Tohoku-Oki event offshore Japan, was presented in this paper.

TL;DR: In this article, the authors demonstrate that seafloor observations and measurements demonstrate deformation that was both extensional and anelastic within the overriding continental plate during the 2011 Tohoku-oki earthquake and propose that the existence of a normal fault that moves the continental crust close to the trench can be considered one indicator of a source area for a huge tsunami.

TL;DR: In this article, the authors describe possible large submarine landslides, several tens of kilometers in length and width, on the trench landward slope of the Japan Trench on the basis of high-resolution topographic surveys and detailed seafloor observations.
