The tropical storm Carlos will not have been right in the eruption of Piton de La Fournaise.
According to the OVPF, the volcanic tremor (surface eruptive intensity indicator) remains at a high level of intensity comparable to that seen at the beginning of the eruption (note that the higher values recorded over the last 24 hours may be Influenced by wind and rain which disrupt the signals).
No seismicity was recorded during the day under the Piton de la Fournaise.
Concerning the long-term deformations, the tendency to a slight recovery of the inflation of the building seems to be clarified. This parameter will be followed and confirmed in the next few days.

The storm prevented field observations, but the processing of the COSMO-SkyMed radar satellite images (carried out by the OI2 platform - OPGC Clermont Ferrand) made it possible to carry out a mapping of the lava flow as it was at 07 February .
This technology and the applied treatment make it possible to identify the surfaces newly covered by the flows and to get rid of the presence of clouds. On the other hand, the resolution of the rendered contours is less than that of the treatments applied in aerial photographs. The length of the lava flows reached an extension of the order of 2,800 meters in eight days ... or at a relatively slow speed of about 15 meters per hour, and is located in the heights of the "Grandes Pentes". After the Broken of the Great Slopes, the lava should accelerate.
A survey conducted on the morning of February 8 by the air section of the gendarmerie and the PGHM confirms the position of the casting front in this sector.

In Etna, after a few days of strombolian activity animating the saddle between the two southeastern cones, this one evolved towards emissions of ashes, frequent on the morning of February 8th. During this active period, the trajectory of the tremor did not vary significantly.

In Hawaii, the site Epic Lava offers a compilation of the activity of 61g lava flow in the last six months.
The arrival of lava waterfall at Kamokuna has not changed in recent days, and there have been no signs of reconstruction of the previously existing lava delta.

A photo taken by the Earth observing-1 / Advanced Land Imager of Nasa and illustrating the various vegetation stages of Kilimanjaro, allows us a good observation of the summit crater ... but also a confirmation of the drastic reduction of its ice cap in some years.
