Probing structure and dynamics of the Chilean subduction margin with high-resolution seismicity The Chilean subduction margin is one of the most seismically active regions worldwide. In the North of Chile, the Atacama segment marks a long-standing seismic gap, with no major earthquake since 1922.…

Crustal stresses and damage evolve throughout the seismic cycle of the Ridgecrest fault zone Earthquakes release tectonic stress abruptly, but this stress builds slowly with time through the coupled evolution of faults and the surrounding crust. Seismic wavespeeds track crustal processes,…

Mantle Dynamics, Continental Breakup, River Drainage, and Biodiversity: A Tale from the Middle East We propose that a large mantle convection cell beneath the Middle East has controlled the topography for the past 30 million years, causing uplift in the Ethiopian–Yemen Dome and subsidence in the…

Paleosols and volcanic rocks weathering: Insights into climate and CO2 consumption during interglacial peaks  Paleosols are exceptional paleoenvironmental archives, yet they remain underutilized in geoscience research. Unlike marine or ice cores, they often lack temporal continuity. However, their…

How large can an earthquake grow?  Effect of geometrical and  energetical barriers. For large earthquakes to occur, seismic ruptures need to propagate  long distances along-strike and overcome different types of barriers. Understanding how far an earthquake can propagate includes assessing the…

Reactivity and bioaccumulation of rare earth elements and metalloids in contrasting hydrological systems: searching for elemental traits and understanding system behaviour The European Union has identified, among many elements, the rare earth elements (REEs), and several metalloids (i.e., arsenic…

Some interesting features of natural and injection-induced earthquake swarms   Earthquake swarms are a peculiar type of earthquake sequence : instead of exhibiting a clear mainshock and the expected seismicity decay after it, they rather consist in a continuous yet moderate seismicity episode.…

A clay story: From structural studies to poroelasticity This presentation will confront insights regarding the role of clay as a marker of geological deformation, and how its structure and fabric influence elastic and poroelastic properties used to discover, appraise, produce and/or store fluids in…

Les radionucléides cosmogéniques et leur utilisation en archéologie et paléoanthropologie Depuis les années 90, le nombre des études s’appuyant sur les quantifications rendues possibles par les nucléides cosmogéniques s’est accru de manière quasi exponentielle, du fait essentiellement des…

Microseism: A Messenger of Earth’s Ocean Environment Ocean activity generates low-frequency seismic waves, known as microseisms, propagating across the world. These waves carry valuable information about their sources (i.e. ocean activity) and the  media they travel through (including crustal…

A perspective on earthquake cycle modelling The modelling of earthquake cycle, including, the stress build up during inter-seismic stage, the nucleation of earthquakes or slow slip events, their propagation and their arrest before building up again the stress, has undergone rapid improvement over…
