Piton de la Fournaise volcano (La Réunion): eruption warning
A new eruption might be under way at the volcano. Since last weekend, seismic activity from a source at 1-2 km depth beneath Dolomieu crater has been increasing. In addition, increased degassing and inflation of the Dolomieu crater have been detected, both likely signs of a new magma intrusion at shallow depth.

The prefecture has closed access to the Enclos. Whether an eruption will occur or not remains to be seen in the coming hours or days. If it does, it would be the third eruption of Piton de la Fournaise in 2015 after the ones in February and May.
Already on 6 July, a similar seismic swarm occurred, but was not followed by an eruption. More than 90 quakes within one hour triggered an eruption alert and the Enclos was closed to the public. The caldera was reopened (with some limitations) on 9 July.

Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 29 July-4 August 2015 (New Activity / Unrest)
OVPDLF reported that a sharp increase in seismicity at Piton de la Fournaise, increased gas emissions, and deformation recorded on 30 July prompted an Alert Level increase and an evacuation. A fissure eruption began the next day at 0920, preceded by 90 minutes of high seismicity and 80 minutes of major deformation; it was confirmed by a hiker and then by observation of a gas plume. A 1-km-long fissure opened in the NE part of the l'Enclos Fouqué caldera and produced dozens of lava fountains. ... Read all
