***King Hammurabi is the best known of the early monarchs of ancient times... belonged to the First Babylonian Dynasty which came to an end, under circumstances shrouded in mystery***

Is there any chance that the massive volcano eruption - Thera (now called Santorini) - could be responsible for the ending due to some date confusion in ancient times?

Nope. The "supereruption" of the mid-2nd millennium is a modern invention. The only large ancient eruption dates to about 199 BC. If I weren't so blamed lazy (and fooling around at work) I'd hunt up the links, meanwhile, look up the keywords you'd expect, Thera, Santorini, Calliste (the former name, according to Herodotus), or Akrotiri (that's the name given the ancient town on the north side of the island).
