The activity at the volcano has been increasing during the past week characterized by increased seismic activity.

According to OVPF the seismicity remaines elevated when instruments detected 1,300 volcano-tectonic earthquakes during 09:30 pm-12:04 pm local time yesterday. Earthquakes were located mainly beneath the summit area and the eastern flank at depths between 1.6 and 5.2 km.
This suggests that a new batch of magma is rising inside the volcano's conduits and pushes its way up to the surface. An eruption is expected in the next few hours.
Instruments recorded rapid ground deformation.
Eruptive fissures open at low altitude as the seismicity is increasing.

Piton de la Fournaise volcano (La Réunion, France): eruption continues; possible increasing of lava flows
OVPF reported that eruption continues on the eastern flank. The seismic station records since 5 April 189 volcano-tectonic earthquakes at approx. 2 km depth beneath the southeastern part of the Dolomieu crater. These earthquakes testify to the weakening of the environment, either by a circulation of fluid or the emptying of a reservoir, most certainly in connection with the feeding of the eruptive site and its renewed activity. A risk of collapse of the crater is not excluded. ... read all
