Hi Christian, thanks for your thoughts. You’re right to note that islands like Iceland, Indonesia, NZ, etc are also where there’s a lot of volcanic activity. Mike Cassidy and Lara Mani briefly summarize potential ash damage in their post on supervolcanoes here (see the table on effects). Basically there could be severe impacts on agriculture and infrastructure. I think the main lesson is that at least two prepared islands would be good. In different hemispheres. That first line of redundancy is probably the most important (also in case one is a target in nuclear war, eg NZ is probably susceptible to an EMP directed at Australia).

Thanks, Matt! That makes sense
