Many Reunion Islanders went to the lava road at dusk to see the lava flows from the eruption in progress at Piton de La Fournaise.

The vision was short-lived, the fog having invaded the Great Slopes for hours, then the rain added.

The duration of the eruption remains a mystery ... the volcano decides!

More news as soon as possible.

Piton de La Fournaise - Illustration of the deformation between December 11, 2019 and February 11, 2020 at 6:44 am. Here are represented baselines (variation of distance between two GPS receivers) crossing the building of Piton de la Fournaise, at the top (top), at the base of the terminal cone (in the middle) and in the far field (bottom ). An increase is synonymous with elongation and therefore swelling of the volcano; conversely, a decrease is synonymous with contraction and therefore deflation of the volcano. - Doc. OVPF
