“PEVOLCA* confirms a further increase in carbon dioxide emissions in El Hierro. The emission of CO2 is one of the parameters of a volcanic eruption precursors but has to be assessed jointly with others, such as deformation and seismicity depth.
Observers also report a faint sulfurous odor.
According to Patrick Allard, Directeur de recherche CNRS, Paris, the eruption is in a transition phase between purely submarine and Surtseyan-type subaerial. The relative calm in the afternoon could have simply resulted from partial removal (collapse?) of the upper part of the new volcanic cone.
New pictures made today (6 Nov 11) HERE.
Increasing CO2 emissions? Hmmm. I wonder why CO2 levels have been rising? Do you suppose volcanoes have anything to do with that?
