OVPF reported that a seismic crisis at Piton de la Fournaise began at 0603 on 11 June and was accompanied by rapid deformation.
Tremor began at 0635, indicating an eruption, though inclement weather conditions prevented visual confirmation; a gas plume was recorded in webcam images.
Scientists observed the eruption during a field visit around 0930, describing at least five active fissures on the SSE flank of Dolomieu Crater.
Weather conditions continued to hinder visual observations.
Three fissures at relatively lower elevations produced 30-m-high lava fountains and lava flows.
Two higher-elevation fissures were no longer active.
By 1530 only the lowest-elevation fissure remained active.
