06:00 AM | BY: VN
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

iton de la Fournaise volcano (La Réunion): new eruption on 2 Jan 2010

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. ...
