This is the second of three posts on the East Hokkaido Caldera Field. This post is centered on the Kutcharo (Kussaro or Kuttyaro) volcanic complex.
Special note to our readers:
Many thanks to all who filled in the survey. A few great suggestions have come in. Now we have to think about the “logistics” to put some of them into action. As we are allowed to keep the survey app running to a certain limit of entries we have decided to put the post up in our top menu. Perhaps the one or other of you still want to have their say. Be reminded that you may answer even just one question and then click the “Finish” button. That’s okay – we appreciate every single bit of input!
The Toya – Usu post led me to the interesting volcanic history of Hokkaido, Japan. Found a multiple caldera complex in eastern Hokkaido with three calderas in close proximity to one another. Will write about these for the next few posts.
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.
