Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 4 February-10 February 2015 (New Activity / Unrest)

OVPDLF reported that 180 earthquakes at Piton de la Fournaise were recorded from 0400 to 0900 on 4 February, including five events greater than M 2. A seismic crisis began at 0910, tremor was recorded at 1050, and an eruption began at 1100. Observers noted that a fissure had opened on the S flank, triggering an Alert Level 2-2 (ongoing eruption) and the restriction of access by the public to the summit area.
The fissure was 500 m long, starting from an area located 100 m outside and to the W of Bory Crater. Activity was concentrated on the southernmost part of the fissure. Lava was ejected from the vent about 10 m high and rapidly flowed SSW towards the Rivals Crater, branched, and spread in an area S and SE of the crater.
By the late afternoon the farthest-reaching branch had traveled past Cornu Crater. Tremor levels decreased through the day and were relatively low by 1800; on 6 February tremor levels were very low. Small cones had formed over the vents and produced low gas plumes.
Inclement weather reduced visibility of the eruption site, although on 8 February observers noted that lava continued to flow from the vents, and another flow traveled further W. On 9 February a vent was weakly active with small explosions and small splashes of lava. Tremor remained stable and low on 10 February.
