After the start of the fissure eruption in Piton de la Fournaise on July 31 at 9:20 am, preceded by 90 minutes of seismic crisis and significant deformations, lava fountains have been easily observed from the Pas de Bellecombe parking, and through the webcam Piton Partage, redirected by the Observatory.

Many fountains (a story talking about 13-14) are active along the fissure that stretches 1,000 meters from the vicinity of the Piton Faujas towards the Nez Coupe of Sainte-Rose. The eruption  fed well the lava flows that descend to a lower area of ​​the Enclosure, the Plain of Osmunds in two main arms. Flow estimates have been made from the gas measurements, and amount to 28 m³ / sec at the beginning of eruption to stabilize around 11 m³ / sec then. A plume of volcanic gas rises between 3220 and 3500 meters in the afternoon. The crack is surrounded by cinder walls. During the day, the level of tremor decreased slightly, and the number of fountains reduced to five in the evening.

The precise instructions from the Gendarmerie have not prevented the congestion on Forest road to the Plaine des Sables last night, many observers are coming to admire, this time easily, the spectacle of fountains lit by the full moon. The cold, at this time of year, did not discourage the bravest who are heading on foot towards the Piton Sharing.

In Papua New Guinea, after strong explosive eruption on 31 July, the Manam volcano emits only dust, and a dark plume. The Madang Provincial disaster management reports no deaths; only two young people in panic during the eruption were injured while fleeing.

An evacuation cannot take place for the time since the shock of the inhabitants ... it concerns more than 5,000 people currently on the island.

The lack of information makes it impossible to be aware of the exact situation, but reports reports of ash fall yesterday around 3:45 p.m. on Bogia on the Guinean coast, and darkness to 13h due to ashes.

The eruption having "open" the magmatic system, the experts suggest that other eruptions may follow.
