Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 September-28 September 2010 (New Activity / Unrest)
Starting on 14 August and continuing through 10 September, OVPDLF recorded a slow but steady increase in the number and magnitude of earthquakes from Piton de la Fournaise. Inflation of the summit area began in late August. A report on 13 September noted localized deformation W of Dolomieu crater and a small number of landslides in the crater.

On 20 September a significant increase in earthquakes was recorded, although the average magnitude was low. The earthquakes were located at the base of Piton de la Fournaise, W and S of Dolomieu crater. A seismic crisis on 24 September was characterized by several tens of earthquakes located beneath Dolomieu crater, and occurred in conjunction with 3 cm of inflation.
The Alert level was raised to 1 ("Probable or Imminent Eruption").

Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 6 January-12 January 2010 (New Activity / Unrest)
OVPDLF reported that during 5-7 January Piton de la Fournaise continued to erupt from a vent along a fissure high up on the SW Dolomieu crater wall. The vent produced lava fountains and flows that pooled in the bottom of the crater. On 7 January the vent closed, but the previously erupted lava continued to flow for the next few days. ... Read all

Piton de la Fournaise volcano greets the new year with its first eruption in 2010 on 2 January. A fissure vent inside the Dolomieu summit crater erupted lava fountains and a lava flow contained inside the crater, deepened by the large eruption in 2008. The eruption followed a gradual increase inseismic activity since Dec 28. The last, very short-lived eruption happened just about 3 weeks ago, and it seems likely that Piton de la Fournaise has entered a period of frequent but short eruptions, fed by dikes in its highly fractured summit zone, forming of a relatively permeable central plumbing system. ...
