Lucilla Benedetti

Project coodinator (CEREGE)
My research aims at understanding the link between plate tectonics, earthquake occurrence and landscape building, particularly in the Mediterranean. I have developed innovative dating methods to constrain the chronology of earthquakes over long time periods (≈ 20,000 years) and specialize in the development of Chlorine-36 to constrain the chronology of surface processes and continental deformation. I also develop approaches based on morphotectonic observations and quantitative morphology to quantify the displacement of Quaternary markers by active faults. I will be involved in WPs 1 and 2 and will ensure the management of the project with partners leaders and WPs leaders.

My main area of interest is the dynamics of the Earth surface, which is a complex interface between internal and external geodynamics. Tectonic and climatic processes interact constantly to shape the evolution of topography, by driving erosion processes and transporting sediments. The general approach I implement in my exploration of Earth Surface Processes is to combine time constraints on these processes using mostly cosmogenic nuclides such as 10Be (integrating rates of surface denudation over the 1-100 ka timescale) with information about the spatial structure of the landscape using high resolution Digital Elevation Models. I also try to integrate these two types of data into a physical understanding of landscape dynamics using numerical Landscape Evolution Models.

Erwan Pathier

Steering commitee (ISTerre)
My research interests focus on the earthquake cycle and its relationship with the continental deformation by measuring and analyzing the different aspects of the earthquake cycle : interseismic phase and its associated transient deformations such as slow earthquakes, coseismic and post-seismic phases. I’m also working on methods for measuring ground deformation from remote sensing techniques with a special interest for space-borne radar imagery and especially radar interferometry techniques.

Oona Scotti

Steering commitee (IRSN)
My reserach interests in the past decade have focused mainly on the developement of approaches to estimate the seismic potential of fault sources based on geologic/geodetic data and physics-based models. My main objective in this project is to set up a link between the different communities presently working in the Central Apennines in order to compare approaches in fault-based Probabilistic Seismic Hazard Assessment constrained by geologic/geodetic data (See WP1 and 2) and physics-based modelling results (WP3 - see Hugo Sanchez-Reyes Post Doc).

Simon Daout

Initially post-doctorate within the project at ISTerre, Simon Daout is now maitre de conférence at Université de Lorraine.
An important part of my research consists of developing synthetic aperture radar (InSAR) methodologies to measure slow surface displacements (few mm/yr) associated with various processes (active tectonics, surface processes, permafrost, etc...). Another research interest is to reconcile long-term (geological or tectonic) and short-term (geodetic) tectonic models. I am particularly interested in the link between active fault behavior and fault geometry. Concerning the EQTIME project in particular, I am working on the large-scale processing and interpretation of InSAR data over the Apennines with colleagues from Isterre. The objectives are 1) to produce large-scale InSAR velocity fields to identify active faults, which load inter-seismic strain or creep at shallow depths 2) to de-convoluate the various sources in the InSAR velocity field: tectonic mantle dynamic, hydrology (WP2, Task 2.2).

Magali Riesner

Post-doctorante within the project
My research aims at understanding the relationship between long-term crustal deformation and active tectonic processes. I am particularly interested by the link between inherited geological structures, the spatio-temporal variability of seismic ruptures and its contribution to seismic hazard assessment. I am using my background in structural geology and paleoseismology to study short-term processes, at the scale of earthquakes, or or several seismic cycles through geomorphological response of landscapes to active tectonics. Within the EQTime project, I al involved in WP 1 and 2. My main focusses are (1) quantifying the long-term deformation on the major active normal fault in the Apennins since the onset of the extension, (2) build a 3D structural model of the Apennines and (3) quantify the quaternary cumulative deformation of the main faults.

Hugo Sanchez Reyes

Post-doctorante within the project
I currently work at the IRSN/BERSSIN as part of the ANR EQTime. I closely work with PhD. Oona Scotti (IRSN), PhD. Sebastien Hok (IRSN) and PhD. Alice-Agnes Gabriel (LMU) on the problem of physics-based dynamic earthquake rupture simulations. Our goal is to better understand and estimate if a considerably large earthquake is probable to occur on complex fault systems where multiple segments could be activated during an important event (WP3).

Léa Pousse-Beltran

Post-doctorate associated
My main interest is to detect and understand spatial and temporal variation of fault behavior. Concerning the EQTIME project in particular, I was involved in the detection of afterslip after the 2016 seismic sequence using INSAR (Pousse-Beltran et al., 2020). I am also involved in the quantification of the slip rate on the major active normal fault in the Apennines (Mt Vettore fault) (Pousse-Beltran et al., in review).

Clément Desormeaux

PhD student associated
I am a third year PhD student at Aix-Marseille University. My work is about the contribution of tectonic and climatic extreme events on long-term landscape building. In the EQ-Time ANR project, I am working on the Magnola-Velino fault system in the Central Apennines and I am interested in the relationship between the rate at which slip accumulates on a fault scarp and the long-term evolution of triangular facets. I use quantitative datasets on normal fault slip rates at various timescales and rates of erosion of the facets and the gullies (36Cl Cosmogenic Nuclides).
