La Palma (Canary Islands (Spain)): Explosive activity continues. Volcanic Ash Advisory Center (VAAC) Toulouse warned about a volcanic ash plume that rose up to estimated 15000 ft (4600 m) altitude or flight level 150 and is moving at 10 kts in S direction.

The lava flows continue to advance towards the coast. According to the latest forecasts, they might reach the sea shore by around 8 p.m. local time, most likely in the area of Playa Nueva in Los Guirres.
Maritime authorities have already established an exclusion zone in the sea, stretching from Punta del Pozo (Puerto Naos) in the south to Las Viñas beach (Tazacorte) in the north, and half a nautical wide. On land, security forces are present to prevent unauthorized access.

The scenario of new eruptive fissures opening might be not that unlikely at all. The surface continues to inflate, which is a sign that more magma is being stored underground that (can erupt) erupts at the surface - the existing paths are not large enough. The volcano might choose to either enlarge them or create new ones.
...20 Sep:
The eruptio in the Cabeza de Vaca area, in El Paso municipality, continues from at least 8 active vents along the two eruptive fissures that opened yesterday at about 200 m distance from each other. The lava has already entered the municipality of Los LLanos de Aridane when crossing the LP2 highway, and is directed towards the centers of La Bombilla and Puerto Naos on the coast.
A sizeable new cinder cone, typically described as “new volcano”, has already formed around the main vent. Lava fountains continue to shoot many tens of meters into the air from the most active vents.
