From fault creep to slow and fast earthquakes in carbonates

A major part of the seismicity striking the Mediterranean area and other regions worldwide is hosted in carbonate rocks. Recent examples are the destructive earthquakes of L'Aquila (M-w 6.1) in 2009 and Norcia (M-w 6.5) in 2016 in central Italy. Surprising ...

Seismic and Microseismic Signatures of Fluids in Rocks: Bridging the Scale Gap

Lucas Xan Pimienta, Christian David

The aim of this collection is to record a snapshot of our current state of understanding of the impact of fluids on the evolution and monitorability of subsurface rock formations during anthropogenic fluid injection/withdrawal operations, accounting for sc ...

Emergence of Cracklike Behavior of Frictional Rupture: The Origin of Stress Drops

Jean-François Molinari, Thibault Didier Roch, Fabian Barras

The process of frictional rupture, i.e., the failure of frictional systems, abounds in the technological and natural world around us, ranging from squealing car brake pads to earthquakes along geological faults. A general framework for understanding and in ...

Can Precursory Moment Release Scale With Earthquake Magnitude? A View From the Laboratory

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Mateo Alejandro Acosta

Today, earthquake precursors remain debated. While precursory slow slip is an important feature of earthquake nucleation, foreshock sequences are not always observed, and their temporal evolution remains poorly constrained. We report on laboratory earthqua ...

Extraordinary wave dynamics in time-Floquet acoustic systems

Romain Christophe Rémy Fleury, Theodoros Koutserimpas

We discuss our recent research advances about wave control and manipulation using periodic temporalmodulation of a system’s properties. By using the unique properties of time-Floquet systems, we constructacoustic metamaterials with extreme effective proper ...

Imitation, Proximity, and Growth - A Collective Swarm Dynamics Approach

Max-Olivier Hongler, Olivier Gallay, Fariba Hashemi

This paper is based on the premise that economic growth is driven by an interplay between innovation and imitation in an economy composed of interacting ̄rms operating in a stochastic environment. A novel approach to modeling imitation is presented based o ...

A-seismic fracture growth driven by fluid injection and remote nucleation of dynamic rupture in a weaker part of the fault

Brice Tanguy Alphonse Lecampion, Andreas Möri, Federico Ciardo

Induced (and triggered) seismicity following fluid injections at depth, is governed by pore pressure diffusion. Interestingly, recent studies yield unrealistically large values of diffusivity in order to explain the timing of the generated seismicity. We i ...

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 ...
