Piton de la Fournaise (France) - Report for 27 February-5 March 2019 - NEW

OVPF reported that the fissure that opened 19 February at a site located at 1,800 m elevation at the foot of Piton Madoré, E of Piton de la Fournaise?s Dolomieu Crater, continued during 27 February-5 March.
RSAM measurements showed fluctuating intensities though an overall upwards trend.
Based on satellite images, the main flow front progressed slowly during 22-28 February, advancing only 300 m to 1,200 m elevation.
A new lava flow emerged from an area near the cone and traveled NE; the more southern branches did not advance during 28 February-1 March.
Scientists conducted fieldwork on 5 March and noted that the cone had grown to 100 m wide at the base, 25 m tall, and had a vent opening 50 m wide.
High-temperature gas emissions rose from the vent, and Strombolian activity ejected material.
White steam rose from the base of the cone, likely from the presence of lava tubes.
The northernmost lava flow remained active.
