The eruption is now almost a week old and shows little signs of stopping anytime soon. Activity is now concentrated at two adjacent vents of a growing cone in the central part of the original eruptive fissure. They are filled with spectacularly boiling (degassing) lava that flows away to form thin flows that overlap on a growing lava field, that slowly but surely is filling the Geldingadalur valley.
The question is of course, how long will it take to fill the valley and get lava reach its lowest pass to the next valley.
Scientists have modeled this: if the current eruption rate of 5.8 cubic meters continues at such rate for a total of 12 days (another 5-6 days from now), it will have filled the valley and start overflowing into the neighboring valley to the SW.
Speculations circulate already that if this eruption continues for a very long time (years), we might see the formation of a new shield volcano. It is impossible to predict this, especially such a short time after the start, but intriguing nevertheless. In any case, we would be now watching the birth phase of a potential shield volcano right now!
