Comparison between measured and modeled postseismic deformation following the 2010, Mw 7.2, El Mayor-Cucapah earthquake. Black vectors and colored circles respectively show horizontal and vertical displacements accumulated over one year following the earthquake measured from GPS. Green vectors and background shading respectively show horizontal and vertical displacements predicted from the model. The model simulates viscoelastic relaxation in the asthenosphere, which is uncommonly shallow in the Salton Trough due to the onset of extension and lithospheric thinning.

Earth's core may be hotter than scientists thought - Jennifer Jackson's group squeezed samples of iron to tremendous pressures using diamond anvil cells, while using infrared laser beams to heat the samples further. They found that at pressures found at Earth's core, iron needs a higher temperature to melt than previously thought. Press release | Advanced Photon Source |

Creeping fault segments, may, in some cases, contribute to massive earthquakes - as shown by new earthquake fault models developed by Nadia Lapusta and Hiroyuki Noda. They hypothesize that this is what occurred in the 2011 magnitude 9.0 Tohoku-Oki Japan earthquake, which was unexpectedly large.
