Piton de la Fournaise volcano (La Réunion Island): eruption pauses and resumes

Eruptive activity remained at the second (lower) fissure at approx. 1500 m altitude, but the output rate of magma is now low.
Last evening, lava emission was taking place from two points on the fissure, feeding multiple lava flow branches that merged after approx. 500 m. Due to the comparably low emission rate, the flow front at between 600 and 650 m altitude had not progressed much and remained at approx. 2 km distance from the road.
Unless the intensity of the eruption increases significantly again, it is unlikely to pose a thread to the road infrastructure at this moment.

Piton de la Fournaise volcano (Reunion Island, France) - Smithsonian / USGS Weekly Volcanic Activity Report for 14 August-20 August 2019 (Continuing Activity)
OVPF reported that the eruption at Piton de la Fournaise that began on the E part of l'Enclos Fouqué at 1620 on 11 August paused for about four hours beginning around 0420 on 15 August; tremor and deep earthquakes indicating magma movement continued to be detected. Lava fountaining resumed at 0830 at two vents residing along the second fissure at 1,500 m elevation, producing flows that did not extend beyond 500 m in length. The lava-flow front from the main flow did not advance past 600-650 elevation. ... Read all

Piton de la Fournaise volcano (La Réunion Island): eruption continues, lava flows only 2 km from coastal road
The eruption on the volcano continues into its 3rd day. Differently from the last short-lived last July, it seems this time it is well-fed and much more intense: lava flows have already reached considerable distance and were only about 2 km away from the coastal road when volcanologists from the observatory (OVPF) could undertake an aerial survey earlier today. ...
