It’s interesting that you should ping me to this. I’ve had this nagging thought in the back of my brain since reading up on what actually happened in Iceland with that volcano, that this isn’t going to be over in a month... not by a long shot.
I picked a different “Black Swan event” in my third novel, (new madrid quakes) but if the 2nd volcano blows for 8 months, it might do the same job on the world economy.
