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).

"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. "

On the second day of the fourth eruption of the year at Piton de La Fournaise.

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.
