Dynamic response of the Chamousset rock column (Western Alps, France)

Modal and thermal analysis of Les Arches unstable rock column (Vercors massif, French Alps)

Present-day uplift of the western Alps

Collisional mountain belts grow as a consequence of continental plate convergence and eventually disappear under the combined effects of gravitational collapse and erosion. Using a decade of GPS data, we show that the western Alps are currently characterized by zero horizontal velocity boundary conditions, offering the opportunity to investigate orogen evolution at the time of cessation of plat...

Influence of Sudden Column Loss on Dynamic Response of Steel Moment Frames under Blast Loading

Modeling buildings response to blast and subsequent progressive collapse interested more and more researchers during the past two decades. Due to the threat from extreme loading, efforts have been made to develop methods of structural analysis and design. In this paper, progressive collapse capacity of steel moment frames was first investigated using alternate load path method, then a nonlinear...

Analysis of rock-fall and rock-fall avalanche seismograms in the French Alps

This study reviews seismograms from 10 rock-fall events recorded between 1992 and 2001 by the permanent seismological network Sismalp in the French Alps. A new seismic magnitude scale was defined, which allowed us to compare and classify ground-motion vibrations generated by these Alpine rock-falls. Each rock-fall has also been characterized by its ground-motion duration t30 at an epicentral di...

Phylogeography of the burnet moth Zygaena transalpina complex: molecular and morphometric differentiation suggests glacial refugia in Southern France, Western France and microrefugia within the Alps

Patterns of common recolonization routes from glacial refugia to Central Europe during the Pleistocene are generalized to paradigms of postglacial recolonization in Europe. Recent studies indicate, however, that the actual phylogeographic history of many species might be more complex and cannot be simplified to generalized patterns. Burnet moths of the Zygaena transalpina complex represent a gr...
