Effects of the Anisotropy of the Fault Zone Permeability on the Timing of Triggered Earthquakes: Insights from 3D-Coupled Fluid Flow and Geomechanical Deformation Modeling

In the last years, numerous seismological evidences have shown a strict correlation between fluid injection and seismicity. An important topic that is currently under discussion in the scientific community concerns the prediction of the earthquake magnitud ...

Electromagnetic Time Reversal Applied to Fault Location: On the Properties of Back-Injected Signals

Mario Paolone, Zhaoyang Wang, Reza Razzaghi

By using the electromagnetic time reversal (EMTR) theory, the paper studies its properties in order to derive a new fault location method to be used in power networks. It is shown that, in the reversed-time stage, the current signal observed at the true fa ...

Frictional Heating Processes and Energy Budget During Laboratory Earthquakes

François Xavier Thibault Passelègue

During an earthquake, part of the released elastic strain energy is dissipated within the slip zone by frictional and fracturing processes, the rest being radiated away via elastic waves. While frictional heating plays a key role in the energy budget of ea ...

Ultra High-Speed Hardware Emulator for Real-Time Fault Location in Multi-Conductor Power Systems

Maher Kayal, François Krummenacher, François Pierre Gaugaz

This research presents a transmission line model aimed for the fault location in power systems using a method based on the Electromagnetic Time-Reversal (EMTR). The discrete-time model simulates the waves travelling in the line by means of many unit delays ...

Unstable Slip Pulses and Earthquake Nucleation as a Nonequilibrium First-Order Phase Transition

Jean-François Molinari, Fabian Barras

The onset of rapid slip along initially quiescent frictional interfaces, the process of “earthquake nucleation,” and dissipative spatiotemporal slippage dynamics play important roles in a broad range of physical systems. Here we first show that interfaces ...

Kariba plunge pool rehabilitation

Anton Schleiss, Giovanni De Cesare, Azin Amini, Ivan Stojnic, Claudia Ylla Arbos

The Kariba Dam is a 128 m high arch dam located on the Zambezi River, between Zambia and Zimbabwe. It forms the Kariba lake, with a surface of 5400 km2 and a capacity of 185 km3. In the 20 years following dam construction, heavy rainfalls required frequent ...

Breaking size-segregation waves and mobility feedback in dense granular avalanches.

Christophe Ancey, Kasper van der Vaart

Through experiments and discrete particle method (DPM) simulations we present evidence for the existence of a recirculating structure, that exists near the front of dense granular avalanches, and is known as a breaking size-segregation (BSS) wave. This is ...

When dynamic cracks meet disorder: A journey along the fracture process zone

Fabian Barras

The onset of earthquakes along crustal faults, the triggering of slab avalanches or the break of a wine glass are all serious problems driven by the propagation of a dynamic rupture front. Our physical understanding of this ubiquitous phenomenon is however ...

Extension of the Unmatched-Media Time Reversal Method to Locate Soft Faults in Transmission Lines

Mario Paolone

An alternative method based on time reversal to locate solid faults in transmission line networks was recently proposed by Codino et al. in the paper “An alternative method for locating faults in transmission line networks based on time reversal” (IEEE Tra ...
