Nature research paper: Intermittent lab earthquakes in dynamically weakening fault gouge
. These plots show that friction increases during event A over slips of roughly 5 μm, while the slip velocity increases from roughly 0.5 m s. In event B , substantial weakening of ~0.15 in friction coefficient occurs over slip scales of just 2 μm or so as slip rate increases. At, weakening of 0.22 occurs over slip scales of approximately 5 μm, again indicating that weakening of 0.1 in friction occurs over slips of 2–3 μm.
. Several attempts to penetrate the rock gouge layer are observed thereafter. Most notably, a rupture at. Next, in sharp contrast with the previous attempts of penetrating the gouge from the left, a prominent dynamic rupture emerges from within the gouge at. This dynamic rupture is initiated close to the location where the previous rupture event arrested
), concentrating shear stress. The rupture initially grows bilaterally, it then expands into the gouge and finally slows down and arrests within the field of view.Experimental measurements of the particle velocity during the second sequence of lab earthquakes along a rock-gouge fault. The video shows the full-field fault-parallel and fault-normal particle velocity over the imaging window, together with their traces along the interface .

Curving the space by non-Hermiticity - Nature CommunicationsThe understanding and control of non-Hermitian phenomena is becoming every day more important. Here the authors establish the duality between non-Hermiticity and curved spaces. It unfolds a geometric root of non-Hermitian phenomena and provides a study and tailor non-Hermiticity using curved spaces.
