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.
