Assessing the effect of lithological setting, block characteristics and slope topography on the runout length of rockfalls in the Alps and on the island of La Réunion [PDF]

Natural Hazards and Earth System Sciences, 2021
In four study areas within different lithological settings and rockfall activity, lidar data were applied for a morphometric analysis of block sizes, block shapes and talus cone characteristics.

Shallow system rejuvenation and magma discharge trends at Piton de la Fournaise volcano (La Réunion Island) [PDF]

, 2017
International audienceBasaltic magma chambers are often characterized by emptying and refilling cycles that influence their evolution in space and time, and the associated eruptive activity.

Petrophysical characterisation of volcanic ejecta to constrain subsurface lithological heterogeneities: implications for edifice stability at basaltic volcanoes

Volcanica, 2021
Piton de la Fournaise (PdF) is a basaltic volcano whose activity is characterized by effusive to mildly explosive eruptions. The geologic record preserves evidence of explosive eruptions associated with the seaward sliding of the steep east flank.

Magma paths at Piton de la Fournaise Volcano

, 2015
International audienceSeveral patterns of magma paths have been proposed since the 1980s for Piton de la Fournaise volcano. Given the significant differences, which are presented here, we propose a reappraisal of the magma intrusion paths using a 17 ...
