Update, Aug. 2019:
In the five years since this was first posted, science continues to grind away, answering a few questions which in turn create a bunch more questions. The Baillie tree ring / ice core team is increasingly of the opinion that the 535 – 540 AD global cooldown was caused by huge volcanic eruptions, at least two of them bracketing the period. A team including Robert A Dull published a paper August 16 entitled “Radiocarbon and geologic evidence reveal ilopango volcano as the source of the colossal ‘mystery’ eruption of 539/40 CE” that appears to nicely define the most recent end of that bracket.

Anak Krakatau a week following flank collapse eruption Dec. 22. The vent region has not yet been rebuilt above water level. Highest remaining part of the island is the hyaloclastic ring that used to host the most recent cone. Note also the island has been resurfaced and grown a bit.

Nisyros: Caldera view from above Nikia village.
So far, when I wrote about volcanoes around the world, I could only dream of ever visiting them. Researching for my first Nisyros post, though, it occurred to me that the idea of a short holiday there was not entirely out-of-bounds. It didn’t take long and I had convinced daughter & granddaughter to come with me. We travelled to Nisyros in October, and, what can I say – it was a wonderful, if too short a holiday! Here are some impressions, thoughts and photos from our visit. Continue Reading
