After a 4 hour break, the Fournaise eruption on La Réunion continues. At first, the eruption was declared over as the tremor dropped towards zero. Then it began to rise again and a new lava flow started to flow from the previously active fissure. Yesterday, only 2 cubic meters of lava per second were produced. The lava front stagnated in the area of the cinder cone Piton Tremblet at 1900 m altitude. In 2007, Piton Tremblet was the scene of a large eruption in which the lava reached the sea. Whether this spectacle will be repeated in the current eruption is questionable. However, 63 volcanotectonic earthquakes have been recorded since the beginning of the eruption, indicating that magma is rising.
Reprise de l’activité éruptive au #PitondelaFournaise après un peu plus de 4h de pause. Suite à l’arrêt de l’éruption ce matin 04h20, le trémor éruptif a repris à 8h30. L’activité de fontaines de lave a repris au sein du même cône éruptif (photo du cône le 13/08/2019 ©OVPF-IPGP) pic.twitter.com/FyTBTnRbRg
