Weakly alimented lava flows continue to run from the 500 m vent at the volcano.

Thu, 19 Apr 2007, 09:13

Both tremor and the lava output have been strongly decreasing over the past days at Fournaise volcano, suggesting a possible end of the eruption in the near future.

On 12 April at 15h05 local time, a second larger collapse took place at the summit crater Dolomieu. The new impressive pit crater has cut the area next to the pit crater Bory, which is now no longer supported and itself at risk of collapsing into Dolomieu.

On 11 April, the eruption resumed at Piton de la Fournaise: new weak lava fountains appeared again at the fissure vent at around 500 m elevation, the same that opened on 2nd of April.

Wed, 11 Apr 2007, 04:37

The eruption at Fournaise volcano seems to come to an end.
On late 9 April, no surface lava flows were visible and all lava from the vent is flowing in lava tunnels on the slope of the Grande Brulée. At 14h00 local time on 10 April, lava fountains ended and lava emission at the vents stopped, triggering scientist to announce the end of the eruption. In the evening, only small residual lava flows were observed, probably relating to drainage of the feeding system and the lava channels and tubes.
During the past days, further smaller collapses have continued to affect the walls of the summit crater. The area surrounding the summit is covered with a deposit of 5-7 cm of ash.
A large number of dead deep-water fish have been found floating on the heated water surrounding the lava sea entry. More than 30 different species have been counted by scientist, some of which seem to be unknown.

Mon, 9 Apr 2007, 19:35

The eruption at Piton de la Fournaise volcano continues and eruptive activity, lava fountains and lava flow emissions from the fissure vent at 600-500 m elevation, increases.

After the collapse of the summit crater, the eruption seems to have calmed down a bit compared to the extreme levels ovbserved during the past days. Lva fountains of 50-100 m height continue to feed a cluster of lava flows that have cut the national road on a length of 1 km and are creating new land at a spectacular, growing sea entry delta. Steam loaded with acid gasses and Pele's hair created at the sea entry continue to create health problems in much of the nearby, inhabited coastal areas.

As had been forecasted by scientists, the summit of Piton de la Fournaise volcano has collapsed today (7 April). Practically all of the interior of Dolomieu crater has collapsed into a new pit crater with vertical walls and 300 m depth, with an estimated collapse volume of 50 million cubic meters. 
The activity has been accompanied by strong earthquakes beneath the summit and produced dense ash clouds. At present, seismic activity continues in the area below the summit; further collapse could happen in the near future.
The series of events at Piton de la Fournaise marks one of the largest pit craters to be formed ever observed in historic time on a volcano.
In the meanwhile, lava emission at extremely high rates from the eruptive fissure continues.

The debit of the lava flow has reached unusually high levels, as a report from the volcano observatory communicates: "...probably much higher than 100 m3 per second, a value which has not been observed at Réunion Island within the last 20 or 30 years. The national road is cut over more than 1 km."

"High values of sometimes over 300 micrograms per m3 of SO2 had been measured by the Observatoire Réunionnais de l’Air (ORA) in the western and northern part of the island.
Dust and Pele’s hair from the eruption site were observed even at 10 to 20 km away and small, mm sized grains of basalt, formed by the lava flow into the sea and transported by the steam plume (generated at the lava flow entry into the sea) were observed within 5 km of the site.

As correctly predicted by the monitoring staff, new eruptive activity restarted at 10h00 local time on 1 April after a two-day pause. New lava fountains and flows are emerging from a fissure in the SE part of the Enclos. The lowest part of the eruptive fissure is only at 500 m elevation and lava flows have been advancing rapidly; at 14h00 local time, they were only 300 m away from the National Road RN2.
