OVPDLF reported that scientists conducting fieldwork at Piton de la Fournaise during 31 August-1 September observed one active cone (20 m high) filled with a lava lake. Fluctuating lava fountains rose 15-20 m above the lake surface and gas bubbles exploded. Lava traveled through a 50-m-long lava channel and was a total of 1 km long.
During 1-2 September seismicity increased, and the lava flow length increased to 2 km. Tremor remained high on 5 September. The lava lake was in two separate but side-by-side vents and lava fountains were lower compared to recent days.
Five small lava flows were near the foot of the cone; four were 30 m long and the fifth was 1 km long. Tremor levels started to decline on 7 September but remained at a high level through 9 September.

One vent remained active, and lava flows from that vent traveled at least as far as 3.5 km. At daybreak on 28 August a small plume rose 400 m and drifted S; inclement weather prevented views during most of the day. ... Read all
