AND FOUR !!
After the increase in seismic activity recorded to day , the Piton de la Fournaise erupted this Monday, August 24 at 18:50 for the fourth consecutive time this year!
According to information provided by the Observatory of the Plain of Cafres , the eruption occurs south of the Dolomieu crater, on RIVALS crater. The beginning of eruption is spectacular and seems important enough (according to Nicolas Villeneuve, Director of the Observatory of Volcanology).
This eruption is clearly visible from the Piton de Bert, like the eruption of May. So 1h30 walk from the « foc foc » parking, on a very easy trail, flat and extremely stable; But it is cold!! Do not forget your polar, gloves and a headlamp if you go at night.
Consequently, the prefect of Reunion triggered today at 19h, the alert plan « ORSEC * 2-2 ,Volcano » ongoing eruption.
Public access to the Enclos Fouqué, whether from the path of Pas de Bellecombe or from any other path as well as the helicopter landing in the volcano area remain strictly prohibited until further notice. The National Forestry Office is responsible for ensuring the implementation of these security measures on the site.
Nearly three weeks after the end of the third eruptive phase of the year 2015, the Piton de la Fournaise is once again erupted on Monday shortly before 19 hours. Two eruptive fissures were visible that night on the side of crater Rivals and below the crater Bory , opposite of the Pas de Bellecombe.
It’s early evening, at 6:50 p.m. precise, a first eruptive fissure has appeared in the south of the Enclos , at the Rivals crater, which triggered the alert 2-2 « Current Eruption « of state services. According to specialists present on the site, « the crack spitted lapilis to the crater Caubet a few hundred meters away« causing an impressive plume of smoke into the sky. Adorned with majestic red-orange dress, this column of smoke was visible from the whole of South and East coasts and a small part of the western region thus causing the arrival of tourists and night owls from all over the island.
Two cracks and « spreading of the intrusion of magma«
At the site, at over 2000 meters altitude it’s from the Piton de Bert, a one-hour walk from the car park of Foc Foc, the view was most successful last night. Shortly after 21:15, a second eruptive fissure, less powerful than the first, appeared to the three–quarter top of the slope of the summit crater, north–northwest of the Bory with two lava flows. Came from Pas de Bellecombe to enjoy a sky with fiery reflections, the curious had the chance to see this show live, by 2 ° C.
« We have currently seismic crisis data, but it is still too early to say. The stabilization of an eruption is something very fragile and, with the opening of a second eruptive fissure more than two hours after the start of this phase, we see that there is a propagation of the magma instrusion (Dyke) in the Enclos , « confided Monday at 22 hours, the director of the Piton de la Fournaise Volcano Observatory (OVPF), Nicolas Villeneuve.
