Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 13 October-19 October 2010 (New Activity / Unrest)
OVPDLF reported that an eruption from Piton de la Fournaise began on 14 October near the Château Fort crater, about 1.5 km SE of the Dolomieu crater rim, after a seismic crisis was detected a few hours before. Lava fountaining occurred from four vents along a fissure. The Alert level was raised to 2 ("eruption in progress in the Fouqué caldera").

By 16 October, lava had traveled 1.6 km ESE, and was confined inside the Fouqué caldera. Lava fountains were 10 m high during 16-17 October and rose from two vents. On 17 October only one vent fed the lava flow.
Scientists noted a reduction in tremor, a decrease in the rate of the lava flow, and less intense explosive activity and degassing. On 18 October lava was again ejected from two vents. The next day a hornito formed in the second vent and lava was ejected 5-15 m above a third vent.
