TL;DR: In this article, an analytical solution and numerical tests of the epidemic-type aftershock (ETAS) model for aftershocks are presented, which describes foreshocks, after-shocks and mainshocks on the same footing.

TL;DR: In this paper, the authors used an isotropic kernel to model the spatial distribution of aftershocks for small (m 5.5) mainshocks and smoothed the locations of larger m 2 and larger m 5 earthquakes.

TL;DR: In this article, the authors study the rock fall volume distribution for three rock fall inventories and fit the observed data by a power-law distribution, which has recently been proposed to describe landslide and rock-fall volume distributions, and is also observed for many other natural phenomena, such as volcanic eruptions or earthquakes.

TL;DR: In this article, the authors estimate the relative importance of small and large earthquakes for static stress changes and for earthquake triggering, assuming that earthquakes are triggered by static stress change and that earthquakes were located on a fractal network of dimension D. They also find that small earthquakes are roughly as important to earthquake triggering as larger ones.

TL;DR: In this paper, the Sechilienne rockslide in the French Alps has been monitored since 1985 and the current very active volume is estimated to be up to 5 million m3, located on the border of a slowly moving mass reaching 50-100 million m 3.
