A new eruption started at the volcano at 07:48 local time yesterday.
The eruption followed a seismic crisis, starting at 06:23 local time, typical sign of magma pushing its way towards the surface. The volcanic-seismic tremor continued to evolve until about 07:48 local time accompanied by emissions of gas and water vapor, another tell-tale sign of an impending eruption. The OVFP's seismic network quickly detected the tremor location on the south-southwest flank of the Rivals crater at approx. 2200 m altitude. The tremor gradually decreased since 08:00 local time as a new batch of magma has loosed the pressure within country rocks by reaching the surface (being erupted as lava).
A new eruptive fissure opened on the west of Kala Pélé crater and started to erupt lava fountains, about 20-30 meters tall, from a chain of vents. Fissure vents continue to feed lava flowing down the slope.

Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 September-20 September 2022 (New Activity / Unrest)

OVPF reported that a seismic crisis at Piton de la Fournaise began at 0623 on 19 September. Volcanic tremor located beneath the SSW part of the caldera began at 0748, likely signifying the arrival of magma at the surface, though weather clouds prevented visual confirmation from webcams. Pelotons de Gendarmerie de Haute Montagne (PGHM) teams that were on-site to evacuate people from inside the caldera observed lava fountains 20-30 m high rising from a fissure that had opened E of Piton Kala Pélé. ...
