TL;DR: The spectral element method as discussed by the authors is a high-order variational method for the spatial approximation of elastic-wave equations, which can be used to simulate elastic wave propagation in realistic geological structures involving complieated free surface topography and material interfaces for two- and three-dimensional geometries.

TL;DR: Using data from Global Positioning System networks in Central Chile to infer the static deformation and the kinematics of the 2010 moment magnitude 8.8 Maule megathrust earthquake, it is found that rupture reached shallow depths, probably extending up to the trench.

TL;DR: In this paper, the transient surface flow occurring when a cylindrical pile of dry granular material is suddenly allowed to spread on a horizontal plane is investigated experimentally as a function of the released mass M, the initial aspect ratio a of the granular cylinder pile, the properties of the underlying substrate (smooth or rough, rigid or erodible) and the bead size.

TL;DR: It is shown that the Iquique earthquake broke a central fraction of the so-called northern Chile seismic gap, the last major segment of the South American plate boundary that had not ruptured in the past century, and the remaining locked segments now pose a significant, increased seismic hazard with the potential to host an earthquake with a magnitude of >8.5.

TL;DR: The statistical results of this study provide a quantitative estimate of the dependence of the accuracy with the system size and the value of the self-affine exponent.
