El Hierro volcano (Canary Islands, Spain): continuing earthquakes and tremor feed speculations about a second vent, but not much visible activity

The area of the submarine vent seen on Thursday.
Since Wednesday, the submarine activity south of La Restinga is not producing much signs at the surface and seems to have stopped or continuing at much lower levels. A part of the VolcanoDiscovery team is now on location and we can observe the activity directly. Only occasionally, a weak brownish mud seems to reach the surface, sometimes accompanied by foam and / or pumice. It seems likely that the first vent has or is dying.
La Frontera in the El Golfo, almost cut off by the rest of the island due to the tunnel closure, seen at night. People here face frequent earthquakes these days.
In the meanwhile, the recorded seismic activity remains strong, including both continuing harmonic tremor, suggesting magma movements, and deep (around 20 km) earthquakes, 10-20 per day usually, NW of El Hierro in the El Golfo area. There are speculations about a possible new vent in this area, but if it is present, it does not (yet) manifest itself at the water surface.
When new significant news become available, we will report them here.

El Hierro volcano (Canary Islands, Spain): earthquake in the El Golfo area, increasing steam and ash fountains and CO2 emissions
Tuesday, Nov 08, 2011
Explosions above the still submarine vents south of El Hierro are getting stronger and follow one another every 10 to 15 minutes, generating large clouds and sometimes jets of gas, steam and ash mixed with blocks rising to 30-35 meters. At night, red glow is visible above the jacuzzi. ... [meer...]

Signs are increasing that the submarine eruption south of El Hierro could be breaking the ocean surface very soon. At the moment, there are 2 areas with violent bubbling fountains (locally called "jacuzzi") up to 20 m high where the water temperature has increased by at least 10 deg C. Occasionally, the first small explosions are seen ejecting rocks, pumice and ash. ... [meer...]

Seismic activity beneath the El Golfo region has further increased and there is now a strong tremor signal. This suggests that a second submarine vent might in fact have started to erupt. [meer...]
