There are some pretty nifty ones which do things like look through old Icelandic literature (and the Bible and Quran) for reports on tales of eruptions handed down through various means before being recorded into an official historical document, and how people coped with the after effects (and maybe an explanation for the fabled Fimbulwinter of Norse mynthology), as well as directly examining the remains of archaeological evidence from hunter-gatherers several thousands of years BCE.

Offered worldwide through May, available from the university’s website as their featured English-language Free Book of the Month selection.
