"Infrared imagery from the Metop satellite showed a possible rising steam plume from the area of Siple on 20 June. The imagery, as interpreted by Mark Drapes, indicated that the volcano was about -22 degrees Celsius, about 6 degrees warmer that the surrounding landscape, and the base of the plume was about -55 degrees Celsius.

The most interesting volcano-related event at the moment is certainly the seismic crisis on El Hierro where the high-intensity earthquake swarm accompanied by tremor episodes continues. The quakes, still at "safe" 20 km depth, have now migrated to the El Julan coast where magma could be accumulating. ... read all

A new eruption might be under way at El Hierro (Canary Islands, Spain). Following several weaker swarms in the past weeks, a strong swarm started late on 24 June and increased dramatically to more than 200 earthquakes of M1.5 or more, including volcanic tremor. The quakes locations indicated that magma was moving at depth from N towards the S in a similar way as at the start of the 2011 submarine eruption. Therefore, the possibility of renewed eruptive activity is real. ... read all
