Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 23 September-29 September 2015 (New Activity / Unrest)

Ср, 23 сен 2015, 06:00
On 24 September OVPDLF reported that, since 20 September, seismicity, deformation, and gas emissions at Piton de la Fournaise stabilized but remained at high levels. The cone was 30 m high; lava fountains were lower and less frequently observed. A white water vapor plume rose from the vents.
Lava flows continued to be active, mainly traveling as far as 3 km S and less than 3 km E. During 22-23 September a new lava tube formed to the W of the lava field.

Since the beginning of the eruption deformation data indicated no deflation. Early on in the eruption the flow rate decreased from 60 cubic meters per second to between 5 and 10; the rate declined during 28 August-7 September and then increased again, starting on 7 September.
