Geology and Morphostructural Evolution of Piton de la Fournaise [PDF]

, 2015
The morphology of Piton de la Fournaise volcano results from the succession of construction, destruction and deformation processes that occurred since at least 530 ka. The chaotic surface of the gently dipping submarine flanks indicates that volcaniclastic deposits related to massive flank landslides and erosion cover most of the submarine flanks. Only

Past volcanic activity predisposes an endemic threatened seabird to negative anthropogenic impacts [PDF]

Scientific Reports
Humans are regularly cited as the main driver of current biodiversity extinction, but the impact of historic volcanic activity is often overlooked. Pre-human evidence of wildlife abundance and diversity are essential for disentangling anthropogenic ...

Jerk, a promising tool for early warning of volcanic eruptions [PDF]

Nature Communications
Forecasting volcanic eruptions remains a great civil defense challenge in many parts of the world. Although instrumental monitoring networks provide a variety of signals interpretable as eruption precursors, volcano observatories still lack a systemic ...

Lava flow daily monitoring: the case of the 19 September–5 October 2022 eruption at Piton de la Fournaise

Volcanica, 2023
Taking prompt and effective actions to mitigate risks associated with an effusive eruption greatly depends on the monitoring of lava flow emplacement. Here we report on the monitoring of the lava flow emplaced during the 19 September to 05 October 2022 ...
