Piton de la Fournaise , La Réunion: The activity on the site remained at a sustained level.

The current eruption continues.

The August 31 and September 1, several recognitions on the ground were performed. The activity on the site remained at a sustained level:
A single eruptive mouth remains active. This is a cone of twenty meters and occupied by a lava lake. At each exploding gas bubbles, fountains (rhythmic) amounted to 15-20 meters above the cone.
At the end of a long tunnel approximately 50 meters a flow escapes to the south for about 1 km. On average broad of 2 to 3 meters , this flow thickens the existing lava field. The front of the flow is fixed.

Wednesday’s activity Bulletin September 2, 2015 at 10:00 am (local time)

The devices of OVPF recorded a further increase of seismic energy (RSAM Rivals) for about 36 hours.

The analyzes (optical imaging, luminescence and gas flow via satellite) show that the flow rate is constant for several days.
The degassing is important in proximal area of the vent and that until the Plaine des Sables (this is variable depending on the wind) but the concentrations are more diffuse in distal areas (cf. ORA and OPAR).

Under the various observations and measurements, we believe that the observed increase in tremor is related to the construction of the cone and the narrowing of the supply conduit which creates intense ground vibrations . Moreover, the rate and intensity of lava fountains continue to fluctuate during the day.
