As Iceland's eruption goes on, lava might fill the valley and overflow to the next one
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!
Lava is estimated to fill the valley and overflow to the SW after about 12 days of eruption (we are 6 days in). Here are two model results for 12 and 17 days with a constant flow of ~5.8 m³/s. Will be interesting to see how accurate Mr. Lava Loba's forecast turns out to be. pic.twitter.com/yNaU9QxRd7— Ragnar Heiðar Þrastarson (@RagnarHeidar) March 25, 2021
