What Happens When Two Ruptures Collide?
Autor: Soumaya Latour, François Passelègue, Federica Paglialunga, Corentin Noël, Jean‐Paul Ampuero
Publikováno v: Geophysical Research Letters, Vol 51, Iss 20, Pp n/a-n/a (2024)
Abstract We investigate the interaction between two rupture fronts as they propagate toward each other and ultimately collide. This phenomenon was observed during laboratory experiments conducted on poly methyl methacrylate. Subsequently, we used num

SUMMARY An unusual seismic activity has recently occurred in the Gripp valley, located in the central part of the French Pyrenees. Since spring 2020, two new swarms appeared, clearly outside the usual location of the seismicity in this area. On 20 Se

Experimental observations of rupture nucleation phase on heterogeneous interface
Autor: Alisson Gounon, Soumaya Latour, Jean Letort
With friction experiments, we investigate the rupture dynamics process, in particular the nucleation part, of laboratory earthquakes conducted on a periodically heterogeneous interface between two polycarbonate plates. Thanks to photoelasticity we fo

Improving depth estimations of African earthquakes using teleseismic data, and influence for the East-African rift seismic hazard characterization

Geophysical Journal International, 2021, ⟨10.1093/gji/ggab348⟩
SUMMARY Well-constrained earthquake depth estimations are important for seismic hazard determination. As local networks of the East-African Rift are usually too sparse for reliable depth estimations, we used detections of pP and sP phase arrivals (th

Ultrafast ultrasound captures dynamic rupture behavior
Autor: Johannes Aichele, Soumaya Latour, Philippe Roux, Stefan Catheline, Christophe Voisin
Publikováno v: Proceedings of Meetings on Acoustics
We apply shear wave elastography, a medical imaging technique that uses ultrafast ultrasound to analyze rupture nucleation. In order to better understand friction and rupture processes which are responsible for earthquake nucleation, we build a labor

International audience; To get an insight into the processes underlying dynamic friction that plays an important role in seismic sources for example, we developed a sliding dynamic experiment coupled to elastography imaging. This experimental setup p

Effects of heterogeneity on rupture dynamics : a numerical and experimantal study
Autor: Soumaya Latour
Publikováno v: Sciences de la Terre. Université de Grenoble, 2011. Français. ⟨NNT : 2011GRENU055⟩

Seismic rupture dynamics can be highly dependent on the heterogeneity of faults, modelised by heterogeneity of the friction properties. We address this issue both numericaly and experimentaly. In the numerical study, we study the effects of small sca

18p.; International audience; We address the problem of modeling dynamic rupture on multiscale heterogeneous faults in 3D. Under the assumption of slip-weakening friction, we numerically construct effective friction laws that integrate the effects of
