OVPF reported that the eruption at Piton de la Fournaise continued during 28 April-4 May, though inclement weather obscured visual observations during most of the week.
Both craters were active, producing lava flows that mainly traveled though lava tubes.
Lava emerged from the end of the flow field, advancing E and setting fire to local vegetation.
Minor inflation of the summit area was recorded.
Lava fountaining was weak at the smaller vent to the SE during 3-4 May and a small lava pond occupied the crater of the larger cone, just NW at the higher elevation.
On 4 May weak fountaining at the smaller cone occasionally ejected material just above the crater rim and the pond was active in the larger crater.
The lava flow advanced another 180 m, reaching 1,500 m elevation.
According to a news article two students in their 20s were found dead in the caldera on 22 April, near the active cones.
The cause of death was not immediately known.
The Alert Level remained at 2-2.
