On April 9th 2021 at 15:00 UTC, a new eruption started at Piton de La Fournaise volcano, La Réunion Island, Indian Ocean (http://www.ipgp.fr/fr/ovpf/actualites-ovpf). The two main vents are located 700 m to the SW of Château Fort Crater at the southern base of the summit cone (Figs. 1 & 2). On morning of April 12, the lava flow has traveled ~3 km to the ESE of the vents. Using C-band Sentinel-1 data provided by European Space Agency (ESA), the OI2/ISDeform/INSU Observation Service has imaged the ground surface displacements induced by the eruption.
The interferograms was produced by the OI2/ISDeform/INSU Observation Service, using the Diapason software (Altamira-Information). This work was supported by public funds from INSU.
