Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 18 June-24 June 2014 (New Activity / Unrest)

06:00 AM | VON: VN
OVPDLF reported that an eruption began at Piton de la Fournaise at 0120 on 21 June 2014 following a period of elevated seismicity. This new activity marks the end of more than three years of quiescence.



During 7-20 June volcano-tectonic and rockfall-type earthquakes were recorded, with the largest number occurring on 17 June. The locations of these earthquakes were relatively consistent between 500 and 1,200 m a.s.l. within Dolomieu crater.
There were neither significant gas emissions nor indicators of pre-eruptive deformation. On 19 June, a field campaign by the Observatory team confirmed the activity detected by the permanent monitoring network (geodetic, thermal, and gas).



At 0006 on 21 June the seismic crises escalated and continued for 74 minutes. Localized deformation began at 0020 and continued for ~3 hours. Tremor began at 0120 and incandescence was observed by the remote cameras at 0135.
The eruption was entirely contained within the Enclos Fouqué area on the ESE side of the central cone. Aerial observations by helicopter revealed an active lava fountain from a fissure that was within view of the Piton Bert webcamera. The fountaining built a spatter rampart and two lava flows extended ~1.5 km from the fissure.
One lava flow extended 250 m after passing the Langlois crater (~2 km SE of Dolomieu crater); the second lava flow passed that crater on the E and S edge and extended an additional 500 m.



Public access to the volcano was restricted on 21 June and Alert Level 1 (“probable or imminent eruption”) was announced.
