On September 13, the eruption at Piton de La Fournaise is stabilized to the bottom of the fissure, and lava overflows from the breached spatter cone under pahoehoe form, and spread to form a lava field.

Field observations made on September 14 by the teams of OVPF show the construction of two volcanic cones on the lower part of the eruptive fissures that have opened on the 1st day. The northernmost cone is breached to the north, where lava flows escape towards the north-northeast. The height of the lava fountains has been estimated at 20-30 m.

On White Island, the volcanic activity of September 13 and during the following night, characterized by emission of ash by (a) vent (s) within the active crater, is classified as minor by volcanologists from GeoNet.
A visit Wednesday suggests that the emission of ash ceased; accordingly, the level of volcanic alert was lowered to 2 and the aviation code is passed from orange to yellow.
