The eruption that began September 15 at 4:25 local time at Piton de La Fournaise continues. The volcanic tremor (indicator of eruptive intensity at the surface) has been stable and weak since 18:00 yesterday (14:00 UT).
Piton de La Fournaise - Evolution of the RSAM (indicator of the volcanic tremor and the intensity of the eruption) between 04h00 (00h UTC) on September 15th and 10h00 (06h00 UTC) on September 16th on the seismic station of FOR, located in near the crater Château-fort (2000 m altitude southeast of the summit). - OVPF

"Three cracks are currently visible, according to Nicolas Villeneuve.The output of the magma is concentrated in the middle of these cracks, with large fountains of lava about thirty meters high.Two flows of lava leave in two arms and find only one. "
Yesterday at the beginning of the afternoon, the lava flow reached 2.6 km. On September 15, 122 volcano-tectonic earthquakes were recorded.
The SO2 emissions recorded by the OVPF's permanent sensors are much higher than the atmospheric background because the volcanic gas plume is dispersed to the west (and to a lesser extent the south and north of the Enclos), under the influence of a sector flow is. We also record an increase in CO2 emissions from the soil on the volcano massif.
No deformation is noticeable since the beginning of the eruption.
Measurements made by satellite (HOTVOLC service) estimate this morning a flow of lava less than 10 m3 / s.
Field observations near the eruptive mouths are underway.
