En sådan vulkan som det tyder på att den som nu är aktiv igen efter 800 år, kan vara aktiv i åratal.
Jag lägger in ett citat från wikipedia då det här kan bli något unikt för vår tid.
"The increase in lava flow is unusual, as eruption outputs typically decrease with time. Scientists from the University of Iceland hypothesize that there is a large magma reservoir deep under the volcano, not the typical smaller magma chamber associated with these kinds of eruptions that empty over a short time.[70] From the composition of the magma sampled, they also believe that there is a discrete vent feeding the main lava flow from a depth of 17–20 kilometres (11–12 mi) from the Earth's mantle, and may be of a more primitive kind than those previously observed.[71] The eruption may create a new shield volcano if it continues for long enough.[72] The formation of such volcano has not been studied before in real time, this eruption therefore offers insights into the working of the magmatic systems.[10]"
