TL;DR: In this paper, the authors examined morphometric (fractal dimension and circularity), grain size, and exoscopic characteristics of the various types of particles (clasts and matrix) from volcanic debris avalanche deposits of La Reunion Island (Indian Ocean) and demonstrated that syn-transport dynamic disintegration continuously operates with the increasing runout distance from the source down to a grinding limit of 500 μm.

TL;DR: In this paper, a structural evolution of Piton de la Fournaise volcano from 500 000 to 50 000 years is proposed based on a reinterpretation of previous data and a new field campaign.

TL;DR: In this article, a formal stress inversion of earthquake focal mechanisms and deformation structures (faults and dykes) observed on three islands (Mayotte, Anjouan, and Moheli) with a morphologic study of the repartition of onshore and offshore volcanic vents in the area was performed.

TL;DR: In this article, the origin of the steep geometry of the central cone of Piton de la Fournaise volcano and its deformation are examined with a combination of a detailed morphological analysis, field observations, GPS data from the PDE volcano Observatory and numerical models.

TL;DR: In this article, a high precision digital elevation model (DEM) is used to characterize and quantify the present-day deformation along these faults, showing that the Recent to Quaternary formations and landforms affected by the fault activity are only vertically offset.
