The effusive eruption of the volcano continues.
A new fissure vent opened at the current eruptive fissure as reported the Observatoire volcanologique du Piton de la Fournaise (OVPF) in their latest bulletin.
The eruptive fissure currently consists of the one larger principal vent and two smaller ones.
The fountaining at two vents continues to build the cinder cones.
The lava, keeping the flow active, continues to travel towards the Grandes Pentes on the southern slope.
The presence of ascending degassed magma inside the volcano's conduits may indicates the gradually increasing of the discharge rate of the lava flow during 9-13 April.
Emissions of gas and steam glowing plumes, visible at night, rose 800 m-1,100 m above the eruptive fissure and drifted southwest.
Sulfur dioxide (SO2) and carbon dioxide (CO2) emissions continue at elevated levels.
Instruments continue to detect slight ground deformation related to emptying the shallow magma chamber located beneath the Dolomieu crater at depths between 1.5 and 2 km, currently feeding the eruptive site.
