La Palma (Canary Islands (Spain)): More and more details are emerging from multiple media covering the eruption in great detail. At 4:33 p.m., a second fissure opened, about 100 meters above the first one that opened at 3.15 p.m.
The Civil Guard has announced that 5,000 to 10,000 people will be evacuated from the municipalities of El Paso, Los Llanos de Aridane, Fuencaliente and Tazacorte, as the lava flows have begun to descend down the slope. The neighborhood of El Paraíso has already been evacuated.

As of now, local press indicates that at least 1,400 people have already been transferred to the El Paso soccer field. In the same municipality lava has already begun to destroy some homes late in the afternoon.

The Teneguía volcano finally erupted after 8 days of intense seismic crisis this afternoon at 3.15pm. At least two eruptive fissures opened in the area of the Montaña Rajada mountains, located in the municipality of El Paso, and started to erupt spectacular lava fountains from at least 7 individual vents.
Particularly in the beginning of the eruption, the opening of the vents was accompanied by strong explosions generating dense ash plumes as the ground opened to give way to the lava shooting out from underneath. The area of the eruptive fissure is an unpopulated forersted mountain zone, and some forest fires were ignited, but quickly controlled. There are no reports of damages. People are advised to avoid the area. Prior to the eruption, around 50 people with reduced mobility had already been evacuated from nearby areas, and more evacuations are now in progress.

The eruption so far seems to be small and there is not much information available yet. The following video was taken immediately after a small vent opened, producing small lava fountains and an ash plume:

…19 Sep:
Following the increasing seismic activity and the previously suspected beginning of tremor, the volcano erupted short time ago – probably much earlier than most expected.
There are not many details yet, but from initial pictures it seems that a fissure opened on the western flank of La Cumbre Vieja, feeding lava fountains and flows, burning forests and farmland.

IGN confirms that the seismic activity has accelerated in the last hours, with intense surface seismicity between 0 and 6 km and numerous earthquakes felt by the population.
Up to this moment and since the beginning of the series, 6,632 earthquakes have been detected, of which 1,317 have been located. During today, 327 earthquakes have been detected, of which 86 have been located with a maximum magnitude of 3.8 or the earthquake that occurred at 10:16 (UTC), widely felt on the island and with a depth of 2 km.
The maximum accumulated vertical deformation has increased to around 15 cm in the area close to the current seismicity and its distribution is still compatible with a center of pressure in this area.
…19 Sep:
During the past hours, activity has been increasing further. The seismic recordings show continuous ground vibration.
While we are not sure about its origin and the interpretation of these data, it could be volcanic tremor and sign of magma moving underground. If so, the chances of an eruption are now getting even bigger.
…19 Sep:
The seismo-volcanic crisis is intensifying. During the past 24 hours, earthquakes have continued to pick up both in numbers and strength.
The largest so-far quake was a magnitude 3.8 quake at 11:16 local time at 10 km depth, initially reported even as magnitude 4, but later revised. SO far, 5 quakes during the past 24 hours were recorded with magnitudes of 3 or more. All of these were felt by locals.
