Journal ArticleDOI
Intermittent dislocation flow in viscoplastic deformation
M. Carmen Miguel,M. Carmen Miguel,Alessandro Vespignani,Stefano Zapperi,Jérôme Weiss,Jean-Robert Grasso +5 more
TL;DR: It is found that dislocations generate a slowly evolving configuration landscape which coexists with rapid collective rearrangements and should provide a framework for discussing fundamental aspects of plasticity that goes beyond standard mean-field approaches that see plastic deformation as a smooth laminar flow.
Journal ArticleDOI
Poroelastic stressing and induced seismicity near the Lacq gas field, southwestern France
TL;DR: In this paper, the authors compared the observed subsidence and hypocentral distributions with the predicted displacement and stress fields, and found that the relationship between average reservoir pressure drop and subsidence is remarkably linear, lending support to the linear poroelastic model.
Journal ArticleDOI
Probabilistic approach to rock fall hazard assessment: potential of historical data analysis
C. Dussauge-Peisser,Agnès Helmstetter,Jean-Robert Grasso,Didier Hantz,P. Desvarreux,M. Jeannin,A. Giraud +6 more
TL;DR: In this article, the authors study the rock fall volume distribution for three rock fall inventories and fit the observed data by a power-law distribution, which has recently been proposed to describe landslide and rock-fall volume distributions, and is also observed for many other natural phenomena, such as volcanic eruptions or earthquakes.
Journal ArticleDOI
Statistical analysis of rockfall volume distributions: Implications for rockfall dynamics
TL;DR: In this paper, the volume distribution of natural rockfalls on different geological settings (i.e., calcareous cliffs in the French Alps, Grenoble area, and granite Yosemite cliffs, California Sierra) and different volume ranges were analyzed.
Journal ArticleDOI
Seismic precursory patterns before a cliff collapse and critical point phenomena
TL;DR: In this paper, the authors analyse the statistical pattern of seismicity before a 1.2 103 m3 cliff collapse on the Normandie ocean shore, Western France, and show that a power law acceleration of seismic rate and energy in both 40 Hz-1.5 kHz and 2 Hz-10 kHz frequency range, is defined on 3 orders of magnitude, within 2 hours from the collapse time.
