Edit: I see that it looks like they have but residents will be allowed in to retrieve belongings. Is there any chance that an eruption comes in the form of a large scale collapse above the magma chamber…or is that not plausible?
While anything's possible, the trend of recent eruptions in the Reykjanes peninsula have been more of the slow trickling small kind. They have also been relatively off the beaten path, so it's hard to compare ground shifting in the previous places since you likely wouldn't notice it after the fact like you will with pavement and buildings.
It only needs a small scale collapse if your house is standing over the sinkhole while you're inside, so evacuation is probably still the safest bet...
Oh yeah, I wasn’t meaning to suggest that evacuation might not be the correct course, it seems at this point not doing so would be irresponsible. Was just curious about the possibility of something very large occurring given the sinking above the chamber.
